cell can be obtained firstly. Thirdly, calculating a
wind power heat dissipation parameter according to the working parameter and the heat dissipation parameter of the fuel
cell, and calculating a liquid heat dissipation parameter according to the heat dissipation parameter of the fuel cell; wherein the
wind power heat dissipation parameter represents the heat dissipation amount of the gas heat dissipation
system for heat dissipation of the liquid heat dissipation
system, and the liquid heat dissipation parameter represents the heat dissipation amount of the liquid heat dissipation system for heat dissipation of the fuel cell. And then, controlling the gas heat dissipation system to dissipate heat of the liquid heat dissipation system according to the
wind power heat dissipation parameters, and controlling
liquid circulation to dissipate heat of the fuel cell according to the liquid heat dissipation parameters. Therefore, the working states of the gas heat dissipation system and the liquid heat dissipation system can be adjusted in real time, certain environment adaptability is achieved, and heat dissipation can be better conducted on the fuel cell.
