At present, there are five kinds of known types of fuel cells. Its name and adopted the corresponding electrolyte relevant.

(1), alkaline fuel cell (AFC) using potassium hydroxide solution as electrolyte. The efficiency of this electrolyte (up to 60 1 90%), but affected the purity of the impurities, such as carbon dioxide is very sensitive. Operation and thus required the use of pure states of hydrogen and oxygen. This limits its application for space flight and the international engineering and other fields.

(2), proton exchange membrane fuel cell (PEMFC) using thin plastic film as the electrolyte. This electrolyte has a high power-weight ratio and low operating temperature. Are applicable to fixed and mobile devices an ideal material.

(3), phosphoric acid fuel cell (PAFC) use of high temperature 200 ℃ phosphate as its electrolyte. Very suitable for distributed cogeneration systems.

(4), molten carbonate fuel cell (MCFC) operating temperature up to 650 ℃. The efficiency of such batteries, but the material demands of high demand.

(5), solid oxide fuel cell (SOFC) are used in solid-state electrolyte (Diamond oxide), a very good performance. They need to adopt the appropriate course of treatment materials and technology, because the inspiron 2500 battery operating temperature is about 1000 ℃.

At present, some research institutions in the ongoing fuel cell development and research. However, in the internationally recognized, in the past decade, PEMFC technology has been developed to a practical stage. However, its process of industrialization is not yet ripe. But also make further efforts to reduce the cost of this technology.

NOTE: The battery electrolyte contains sulfuric acid, any direct contact will cause skin burns. Making direct contact with the battery before, be sure to make the necessary security protection measures, such as use of protective glasses, gloves. For tools, tools should be enough to protect the insulation.
1, if we find that the sony laptop battery electrode has a white / green / blue crystalline powder accumulation, timely use of wire brush and baking soda (also known as soda) solution cleaning electrodes to ensure good contact with electrodes and cables. (Sodium bicarbonate has corrosive, once to car paint, it is necessary to timely clean-up).
2, check the battery is securely fixed on the battery shelf, if it is loose, tighten the bolts fixed. Excessive shaking will shorten battery life.
3, regularly check whether the reduction of battery electrolyte. If needed, add distilled water, but do not overdose. Normal liquid height should arrive at the bottom of water holes. Maintenance-free batteries are not required to the maintenance.
4, the cable, is checked whether or not closely connected in the electrode. Loose joints will lead to car does not start, it seems like the battery is dead.
5, double-check the sony vgp-bps5  shell, look for cracks or other physical damage. If the battery has cracks, replace the need for timely, in order to prevent the leakage of corrosive electrolyte.

Today this bustling era of digital products, rechargeable batteries more and more important, MP3, digital cameras are the big power. MP3 is also slightly better, a battery can barely support about eight hours, a digital camera is more terror, four rechargeable batteries can shoot 2,300 Zhang is quite satisfactory. Electrical power supply is the heart, plays a key role, the following brief for the U.S. mainstream all aspects of rechargeable battery.
1 rechargeable sony laptop battery effects on electrical appliances and fake hazards
HIFI engage players all know the importance of the power of sound, or even a power cord must sell several thousand dollars, rechargeable battery for the electrical as well, poor battery due to internal use of materials for poor discharge instability, frequent high-volume moment discharge is likely to result in damage to electrical appliances, more deadly, this harm is not immediately effective, but “slow poison”, that is to say you simply can not be aware of is the poor quality battery to your electrical appliances to harm the baby.
Leakage is also easy to inferior rechargeable batteries a big risk, you may have seen many friends have become “very fat and swollen blood” of the battery, this appalling state of the greatest hazards on electrical appliances, often a leakage would have to engage in electrical bad; “unlucky then lucky” is that this kind of inferior rechargeable batteries in the charger sometimes in leakage, rather than undermine, your other electrical appliances.
Inferior rechargeable batteries generally include two kinds: one is very cheap non-brand, 2 are fake brand names. No. 1 kinds of good identification, as long as the U.S. Internet-related knowledge to find out a little aware of the choice on what brand; the first two kinds of very headache, many battery industry veteran told to Dan said: not even their own can not determine the true fake goods goods, watch batteries only purchase channels. But also because not leave the battery will be 1:30 to watch out, so even if the vote to allow merchants to do to ensure that the development also has the effect of difficult.
Currently on the market a lot of rechargeable batteries fakes, it is estimated that the proportion of fakes is really about 8:2, between the real cost of fake goods is almost 40% difference between the real profits of cargo space for a small battery, and wrapped the outside layer of skin it is difficult to see true, so many Italian businessmen are selling counterfeit rechargeable batteries, so to suggest we should go to Dan who has “very good” reputation and credibility of the merchants buy - Shidao sinister, only the brightest along the road before taking will not fall into the trap.sony pcga-bp2s .

Hangzhou Wu Jing Genshan secondary students do not have invented a battery flashlight, rechargeable flashlight as long as shaking a few on the trip, cost is not high. She said this particularly suitable for wild camping torch of ALICE.

Wu Jing is Grade three this year, self-study to go home late, dark corridor so that she was particularly afraid of. High school physics introduce a “magnetic-generated” The classic principles of generation of electricity: magnetic coil cutting line will produce electrical energy; capacitor can store electrical energy generated, and the use of open switch can be generated when the current so that Light-emitting diodes. Wu Jing in accordance with these principles, the invention of the flashlight without batteries: Put the torch a small magnet onto a coil, carrying a flashlight to become a “generator”, shaking flashlight, beating a small magnet and coil sensors will be able to produce electricity a. Now, Wu Jing day with such a flashlight to school after school, she said less than 50 as long as Akira, the torch will be able to light for five minutes.

This invention won the seventeenth session of young people in Zhejiang Province elite first Invention Award, also received a national patent, “I think it particularly suitable for camping in the wild friends, at any time can be leisurely to use a flashlight, Do not worry there is no battery inspiron e1505  or other power. “Wu Jing said,” Although it is very simple principle, but the invention is a moment of inspiration coupled with careful observation of life. “she said of the creative life can also be used in more small household electrical appliances on, creating more energy-efficient appliances.

Ford recently said the United States, hydrogen fuel cell vehicles will need at least 20 years of time to market into the mainstream, mainly by the hydrogen fuel supply pipeline inadequate. “I have not seen a viable and affordable hydrogen fuel economic structure.” Ford’s hydrogen R & D is responsible for IT projects, said Greg Frenette people. “May have to wait until 2030 is possible.”

HONDA this time than the time before the publication of more than twice as much. Ford, HONDA, NISSAN, as well as many other depots, research and development are falling over each viable alternative fuel cars, want to take this to the auto market downturn remember playing one shot in the arm. NISSAN electric vehicle and fuel cell vehicles, senior project engineer Brian Johnston pointed out that the price of hydrogen is equivalent to 10 U.S. dollars a gallon, if the immediate economic effects of view really is not ideal.

Fuel cells produce electricity through chemical action, the only emissions are water vapor, there will be no greenhouse gas carbon dioxide. But Ford did not disclose the purchase, use and manufacture of fuel cell vehicle cost. Japan’s second-largest depot HONDA forecast three years ago to build fuel cell cars cost about one million U.S. dollars. HONDA is now in Los Angeles by way of rental for the public test drive fuel cell vehicle activities.

America’s largest GM also the depot for the three cities about 100 battery car test drive, Ford now has to provide 30 fuel cell vehicles to the public. The United States currently has about 70 hydrogen-fuel filling stations, half of them located in California. In contrast, there are about 140,000 gas stations in general.
