Fuel cell basic introduction
A fuel cell is a chemical device that directly converts the chemical energy of a fuel into electrical energy, also known as an electrochemical generator. It is the fourth generation technology after hydroelectric, thermal and atomic power generation. Since the fuel cell converts the Gibbs free energy part of the chemical energy of the fuel into electrical energy by electrochemical reaction, it is not limited by the Carnot cycle effect, so the efficiency is high; in addition, the fuel cell fuel and oxygen are used as raw materials; There are no mechanical transmission components, so there is no noise pollution, and there are very few harmful gases emitted. It can be seen that fuel cells are the most promising power generation technology from the perspective of energy conservation and ecological protection.
