Background
A fuel cell is a power generation device that can directly convert chemical energy of a fuel and an oxidant into electrical energy. Whether industrial production or scientific research is carried out, the fuel cell is tested. The flow, temperature, humidity, pressure of the cell inlet air need to be controlled during the testing process of the fuel cell. For a fuel cell, the temperature of the cell itself and the temperature of the reactant gases change to directly affect the performance of the cell, so temperature control is very important for fuel cell testing equipment.
The existing fuel cell testing equipment has the problem of slow temperature regulation. In fuel cell testing equipment, both the cathode and anode humidifiers and the circulating water heating water tank require temperature control. The cathode and anode humidifier controls the gas temperature and the gas humidity by controlling the temperature; the circulation heating water tank realizes the control of the temperature of the galvanic pile by controlling the temperature. Generally, during the temperature rising process, the purpose of rapid temperature rising can be achieved because the heating power of the test equipment is large enough. However, in the process of cooling, because no related cooling device is provided, natural cooling or air cooling heat dissipation is realized only by stopping heating, and the cooling time is very slow. If the cooling time is too long, the testing efficiency is low. And the existing temperature control system cannot accurately ensure the temperature control precision.
