Introduction to fuel cell
A fuel cell is a chemical device that directly converts the chemical energy of the fuel into electrical energy, also known as an electrochemical generator. It is the fourth power generation technology after hydropower, thermal power and atomic power. Because the fuel cell converts part of the Gibbs free energy in the chemical energy of the fuel into electric energy through an electrochemical reaction, it is not limited by the Carnot cycle effect, so it has high efficiency; in addition, the fuel cell uses fuel and oxygen as raw materials; at the same time There are no mechanical transmission parts, so there is no noise pollution and very few harmful gases are emitted.
