Since fuel cells convert the Gibbs free energy portion of the chemical energy of a fuel into electrical energy through an electrochemical reaction, they are not limited by the Carnot cycle effect and are therefore highly efficient. Fuel cells use fuel and oxygen as raw materials and have no mechanical transmission parts, so there is no noise pollution and very few harmful gases are emitted. After the fuel cell is produced, the positive and negative electrodes of the fuel cell need to be connected to the test equipment, which will then test the fuel cell. During the test, the positive and negative electrodes of the fuel cell are connected to the test equipment, and the power of the fuel cell is transmitted to the test equipment. The test equipment is used to test the power transmission of the fuel cell per unit time to determine whether the fuel cell meets the production standards.
