What is a fuel cell
A fuel cell is an electrochemical device, which converts the chemical energy of a fuel into electrical energy and heat. Fuel cells contain a gas tight membrane – the electrolyte – and two electrodes – anode & cathode – on either side of it. As long as a fuel like hydrogen and air are led to the electrodes, electricity and heat is produced.
Fuel Cell Systems | Department of Energy
The fuel cell stack is the heart of a fuel cell power system. It generates electricity in the form of direct current (DC) from electrochemical reactions that take place in the fuel cell. A single fuel cell produces less than 1 V, which is insufficient for most applications. Therefore, individual fuel cells are typically combined in series into ...
