Unlimited potential of fuel cells
Although the fuel cell the term appeared in front of the time it did not last long, but it can be traced back to the history of more than 100 years agoHp laptop battery . In 1889, 337607-001 Battery, 337607-003 Battery, dg103a , 336962-001
398876-001 Battery, PB992A Battery, PB994A Battery,Ludwig Mond and Charles Langer two chemists would like to use air and industrial gas to create a practical device to provide power, "fuel cells" as they term it the invention was born. The rise of modern fuel cell technology in the 20th century, 60's, the space shuttle in order to search for high-performance power devices, NASA in cooperation with GE to develop the first modern dell laptop battery fuel cells - proton exchange membrane fuel cell, which is fuel cell the beginning of commercialization. Since then, after 40 years of development, fuel cell family, the more prosperous, but also across the various application areas.
Principles of fuel cells and characteristics of
Fuel cells combine hydrogen and oxygen by the reaction into water to generate electricity and therefore does not produce nitrogen oxides (NOX) and hydrocarbons (HC) and so easy to pollute the air the material. It consists of three components: cathode, anode and electrolyte, in accordance with the different electrolytes can be divided into molten carbonate fuel cell (M CFC), solid oxide fuel cell (SOFC), alkaline fuel cell (AFC ), phosphoric acid fuel cell (PAFC) and proton exchange membrane fuel cell (PEMFC) five types75uyf,1691p , 337607-001 Battery, dell inspiron 2500 battery , dell inspiron 3700 battery.
Fuel cells have several unique properties: 337607-001 Battery, 337607-003 Battery, dg103a , 336962-001

1 fuel cell must be at work, energy
(Fuel) input to output power.
2 by the fuel cell can generate electricity only, and
Fuel supply, as long as the supply of fuel can produce electricity, the discharge is carried out in a row.
3 fuel-cell quality and body size is not large, but the need for a fuel storage device or fuel switching devices and ancillary equipment in order to obtain hydrogen, 337607-003 Battery,which fuel storage device or fuel switching devices and ancillary equipment far exceeds the quality and volume of fuel dell inspiron 3800 battery itself.
Common fuel cell
Proton exchange membrane fuel cell (PEMFC) in proton exchange membrane fuel cell, the electrolyte is a thin polymer film, such as poly [perfluoro methyl] acid (poly [perfluorosulphonic] acid), and proton conductivity but not to penetrate the NafionTM, and by the carbon composition of the basic electrode. Inflow of hydrogen fuel cell to reach the anode, cracking into a hydrogen ion (proton) and electronic. Hydrogen ions to the cathode through the electrolyte penetration, and electronic flow through an external network dell inspiron 4000 battery to provide power.

398876-001 Battery, PB992A Battery, PB994A Battery, to air in the form of oxygen supply to the cathode, with the combination of electronic and hydrogen ions to form water.
Alkaline fuel cell (AFC)
Alkaline electrolyte fuel cell for use in aqueous solution or potassium hydroxide stability matrix,398876-001 Battery, and the electrochemical reaction with the hydroxyl (OH) moved to the anode from the cathode reaction with hydrogen to generate water and electronics is slightly different. First of these to provide energy for the external circuit and then returned to the cathode reaction with oxygen and water to generate more hydroxyl ions dell inspiron 4100 battery , dell inspiron 4150 battery , dell inspiron 8000 battery.
Phosphoric acid fuel cell (PAFC)
This battery acid for the use of liquid electrolyte, the operating temperature than the proton exchange membrane fuel cells and alkaline fuel cell operating temperature is slightly higher, at around 150 ~ 200 ℃, it has to be the platinum electrode catalyst to accelerate the reaction. The anode and cathode reactions and the proton exchange membrane dell inspiron 8100 battery fuel cell, but due to its higher operating temperature,PB992A Battery, so the cathode reaction rate than the proton exchange membrane fuel cell cathode faster.
Molten carbonate fuel cell (MCFC)
Molten carbonate fuel cell using molten lithium potassium or lithium carbonate as the electrolyte of sodium dell inspiron 8200 battery carbonate.337607-001 Battery, 337607-003 Battery, dg103a , 336962-001
398876-001 Battery, PB992A Battery, PB994A Battery, When the temperature is heated to 650 ℃, this salt will melt, producing carbonate ions, the flow of the anode from the cathode, combine with hydrogen to generate water, carbon dioxide and electronic.PB994A Battery, Electronics and then through an external circuit to return to the cathode, generating in the process.
