Fuel Cells
10/20/2008
“A fuel cell is a device that converts the chemical energy of a fuel (hydrogen, natural gas, methanol, gasoline, etc.) and an oxidant (air or oxygen) into electricity. In principle, a fuel cell operates like a battery. Unlike a battery however, a fuel cell does not run down or require recharging. It will produce electricity and heat as long as fuel and an oxidizer are supplied.”
“Both batteries and fuel cells are electrochemical devices. As such, both have a positively charged anode, a negatively charged cathode and an ion-conducting material called an electrolyte. Fuel cells are classified by their electrolyte material. Electrochemical devices generate electricity without combustion of the fuel and oxidizer, as opposed to what occurs with traditional methods of electricity generation.”
“Fuel cell construction generally consists of a fuel electrode (anode) and an
oxidant electrode (cathode) separated by an ion-conducting membrane. Oxygen
passes over one electrode, and hydrogen over the other, generating electricity,
water and heat. Fuel cells chemically combine the molecules of a fuel and
oxidizer without burning or having to dispense with the inefficiencies and
pollution of traditional combustion. “
