Fujitsu hydrogen fuel cell

Fujitsu last Friday Dell Latitude D800 Battery announced that it will use the UTC provided by a 200 kW hydrogen fuel cell power supply station, as well as park construction heating.

This fuel cell-powered form as follows: First, heat produced by steam methane to produce hydrogen. Hydrogen will pass through a “proton-exchange membrane” (PEM), this film will be produced through the reaction of electricity, so as to lighting, computers and other equipment to provide electricity.

In addition, the electricity generated in the process of hot water can be recycled in the building, for building heating. PEM can once again collect part of the heat, but this is part of the hot water temperature is too high, it can only be discharged, but the future this part of the hot water can be used.

While the process will produce Dell Latitude D830 Battery hydrogen to produce carbon dioxide, but better than conventional ways of producing energy with low greenhouse gas emissions about 35%. That is, fewer emissions per year, out of 500 tons of carbon dioxide a year in this way can also save about 80 gallons of water. Conventional power stations a lot of the water main.

Many settings, industrial-scale fuel cells are not well play a role. UTC Vice President of Sales Homer Purcell, said: “If your office 7 days a week, the daily 9 to 5, the fuel cell will not be a good choice.”

Battery recall news

From about 10 years ago, mobile phones sony np-f970 in China began to promote, so far, as a personal and convenient communication tool, mobile phones in the Chinese market has been basically popularized. In the majority of the user’s mind, that should have been relatively quiet the mobile phone market, on entering the second half of 2007 but due to several who paid close attention to the ensuing events: First, Apple’s first smart phone - iphone listing and followed by questions; then Motorola cell phone batteries accidental explosion; Recently, Nokia has announced the recall of 46 million global market, cell phone batteries.

As in the global market from causing hundreds of accidents related to the battery overheating, August 14, 2007, Nokia announced that due to existence of the risk of overheating, will take the initiative in the global recall of 46 million mobile phone batteries manufactured by Matsushita.

Just because there are nearly a hundred-related accidents from occurring, Nokia will result in a global recall of 46 million mobile phone batteries, the direct economic loss is obvious, while this “recall incident” will certainly be the normal operation sony np-bg1 of the Nokia adversely affected.

Since the recalls have brought the loss is obvious, then the Nokia is not making a fuss? Next, let us from the crisis management perspective of bonding since before the accident occurred nearly one hundred to analyze Nokia’s initiative to recall the events of the bar.

1, ahead of the enthusiasm of people praise. The last two years, the “recall” in the major media exposure is very high, from a notebook battery recall, to the digital camera recall, and then to recall more vehicles. Recalled the incident on a variety of point of view with nikon en-el3, for all relevant firms, mostly the choice of last resort because, after all, the recall of such products will bring to the vendor is not a small loss.

This point of view, take the initiative to recall 46 million Nokia batteries practice, with most products when the manufacturer recalled the helplessness of expression in sharp contrast. Starting from nearly one hundred accidents analysis to this group of mobile phone battery safety problems exist, then in the “preventive measures” under the guidance of the concept of the voluntary recall of possible problems of 46 million batteries. Nokia, by virtue of their own initiative to recall, to avoid the recurrence of the accidents and the spread of the crisis, its response to the crisis is hard to praise the initiative of the incident.

2, active popular responsibility. In the wake of the accident, when mobile phone batteries, cell phone manufacturers can take the initiative to assume responsibility for this accident is directly about the crisis will worsen the spread of the decisive factors. At the same time, which is also a party businesses can not get the nikon en-el4 key to the user choice the people.

On this occasion take the initiative to recall events that the mobile phone battery, Nokia with their own actions to fully assume the responsibility of the previous incidents, and a great loss to his own guarantee the safety of our customers use of mobile phones. With such a generous move, Nokia will undoubtedly enjoy the support of the majority of users.

Third, through the media to communicate in good faith. The release of the battery recall information at the same time, Nokia is also using the major authoritative media of the cells involved in the recall of the models is described in detail, and to recall the nikon en-el4a battery identification, carried out a detailed narrative and icon, so that no doubt greatly facilitated since the majority of users of mobile phone batteries recognition.

In addition, according to media reports, since August 15 is the Nokia cell phone battery recall on the first day, due to large number of users to confirm the battery, Nokia’s customer service system for a time in a semi-paralyzed state. Under such unfavorable circumstances, Nokia respect for the general user to indicate that the after-sale hotline, official websites and authorized repair center channel to replace the battery in three ways, so that a single change has been undoubtedly a reasonable diversion channels to ensure that the users cell phone the battery recall and replacement of efficiency.

Event Analysis: As before, there had been nearly a hundred-related accidents from mobile phone batteries, Nokia’s global market, 46 million batteries recalled the initiative, its strong sense of social responsibility and the “preventive measures” in crisis management concepts, and the product recalls many of the enterprises concerned in stark contrast. Nevertheless, a massive battery recall, Nokia will bring huge economic losses, but because of its positive and proactive product recalls, making the occurrence of accidents related to the olympus li-10b battery has been completely resolved, at the same time, Nokia also and won the hearts of customers to successfully defused a crisis that may arise outside of the decision.

Final needs to be emphasized is that Nokia only been able to achieve the success of this deal with the digital camera battery incident, instead of “preventive measures” sense of crisis is inseparable from public relations, it is by virtue of an unprecedented sense of crisis, only to survive Nokia of the difficulties. Hope that the broad domestic enterprises to be able to Nokia as a benchmark, to correctly understand and deal with unexpected public relations crisis.

Carbon nanotube battery

New York State sony vgp-bpl9 battery Technological University - Rensselaer Polytechnic Institute (RPI) announced the development of cellulose and carbon nanotubes by the electric double layer capacitors, as well as the composition of Li-ion battery (in English published data). The thickness of these components is only tens of μm, the thickness of a human hair can be like a paper-bending. RPI researchers that “the future can take advantage of Roll to Roll printing technology manufactured batteries.” Technical details will be August 21, 2007 published in the academic journal “Proceedings of the National Academy of Sciences” published.

RPI development of the following results: (1) developed to enable multi-layer carbon nanotubes (MWNT: multi-walled nanotubes) in order to form a brush shape as the main components of cellulose, cellulose membrane; (2) the use of two cellulose membranes made electric double layer capacitors; (3) using a cellulose membrane and the lithium electrode made of lithium batteries.

Cellulose membrane as porous membranes sony vgp-bps10 battery, use of the former need to penetrate up to 25% of the weight ratio of ionic liquids, etc. (RTIL: room-temperature ionic liquid) - [Bmin] [Cl] (1-butyl ,3-methylimidazolium chloride). RPI will be two of the film laminate, so that MWNT brush outwards, and then in the lateral formation of titanium (Ti / Au) film as an electrode, made of electric double layer capacitors. On the other hand, lithium batteries is to give a thin film laminate with the lithium electrode in the middle clip into lithium hexafluorophosphate (LiPF6) ionic liquid electrolyte instead of the outside foil electrodes attached. Two kinds of components, manufacturing methods were not open.

Electric double layer capacitor used in [Bmin] [Cl] ionic liquid has not volatile and so can be in a larger temperature range stability. Such ionic liquids through cellulose membrane pore diameter of 50 ± 5nm contact with the charge.

In the frozen bank and in vivo work can

The performance of electric double layer capacitor is as follows: electrostatic capacity of 22F / g, maximum operating voltage of 2.3V, the energy density of about 13Wh/kg, capacity of the existing electric double layer capacitor level. The weight per unit area of only 15mg/cm2, very light, and because [Bmin] [Cl] does not contain moisture, so the device operating temperature range is very large, reaching -77 ~ +150 ℃. The device, when the temperature dropped to -196 ℃ Although it is impossible sony vgp-bps10/b battery as a capacitor, but the temperature rise after full recovery. RPI is now confirmed that the components in repeated charge and discharge over 100 times, they could still maintain good features.

RPI said that apart from ionic liquids, the use of the component potassium hydroxide (KOH) aqueous solution and human blood, sweat, urine and other body fluids as the electrolyte to achieve the same performance of the work. Therefore, the body is also expected to work as a pacemaker and other equipment with batteries.

Capacitor and rechargeable batteries for hybrid components are also expected to realize

Lithium battery charging voltage up to 3.6V, in order to 10mA / g for a fixed output power of discharge. Battery capacity in the first charging up to 430mAh / g, but the 2nd charge will be reduced to 110mAh / g below.

In the future, RPI plans to build integrated electric double layer capacitors and lithium sony vgp-bps10/s battery for hybrid components. The component is estimated to be, “which can play both characteristics of the capacitor and rechargeable batteries fully mixed” (RPI).
