As the fuel cell technology matures, the application of the fuel cell technology to automobiles increases, but due to the characteristics of the fuel cell, the application of the fuel cell technology to automobiles has more limitations compared with the traditional automobiles. Among them, the fuel cell is particularly sensitive to temperature. As the water temperature increases from low to high, the efficiency of the fuel cell increases gradually, but the water temperature exceeds a certain limit (generally 80 ℃), which in turn affects the catalyst and the reaction efficiency. Therefore, the operating temperature range of the general fuel cell is required to be 70-80 ℃, and the temperature range is narrower compared with that of the traditional fuel vehicle.
The cooling heat exchange at the front end of the fuel cell is the same as that of the traditional fuel vehicle, and the forced convection heat exchange is carried out by utilizing the temperature difference between the ambient temperature and the cooling liquid and the air flow. Under the same vehicle state, different ambient temperature heat exchange effects are greatly different. The wide breadth of China and the large temperature difference in the four seasons, if the same temperature control logic is used to control the thermostat and the wind speed and the rotating speed, the water temperature fluctuation is obvious and is not easy to be stable.
Therefore, in order to control the water temperature of the cooling system of the fuel cell more accurately, the control logics of the cooling system under different environmental temperatures are designed to achieve more excellent performance of the fuel cell.
