A fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction with oxygen or another oxidizing agent. A fuel cell consists of two electrodes, namely an anode and a cathode. Anode is positively charged and cathode is negatively charged in an electrolytic cell. The reactions that produce electricity take place at the electrodes. Every fuel has an electrolyte, which carries electrically charged particles from ...
