Abstract

An embodiment of the invention provides a temperature control method of a fuel cell system and related equipment. The temperature control method of the fuel cell system is applied to the fuel cell system. The temperature control method of the fuel cell system comprises the steps of: acquiring a stack temperature; judging whether the pile temperature is less than or equal to a first preset temperature; and when the pile temperature is less than or equal to the first preset temperature, controlling the reaction rate of the pile to be reduced. According to the temperature control method of the invention, when the temperature of the galvanic pile is lower than the first preset temperature, the efficiency of the galvanic pile is controlled to be reduced, the heat dissipating capacity of the galvanic pile is increased, the temperature of the galvanic pile is improved, the time required for raising the galvanic pile to the optimal working temperature is shortened, the power consumption of the fuel cell system is reduced, and the use performance of the fuel cell system is improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of fuel cell systems, in particular, to a temperature control method and related equipment for a fuel cell system Background technique [0002] In the prior art, the temperature of the electric stack affects the reaction efficiency of the electric stack. The reaction efficiency of the stack is the highest at the optimum working temperature, and the reaction efficiency of the stack will decrease if the temperature is too high or too low. [0003] The optimum working temperature of the electric stack is usually between 50°C and 60°C, and when the fuel cell system is started, the temperature of the electric stack is close to the ambient temperature, usually around 20°C, which is lower than the optimum operating temperature of the electric stack. After the stack is started, it takes about 5 minutes to rise from the ambient temperature to the optimum working temperature. During this ...
