Example Embodiment
[0039] The present invention will be described in detail below with reference to the accompanying drawings and specific implementation cases. This example is implemented on the premise of the technical solution of the present invention, and a detailed implementation solution is given, but the protection scope of the present invention is not limited to the following examples.
[0040] This embodiment provides a method for controlling the output voltage of a fuel cell system, such as figure 1 As shown in the figure, it includes two control variables, namely, the air mass flow rate and the cathode inlet air pressure. The two parameters use different control methods to control the output voltage of the fuel cell system. By controlling these two variables, the fuel The output voltage of the battery varies around the desired value.
[0041] like figure 1 As shown, it is a schematic diagram of the system control strategy of the present invention; figure 2 It is a schematic diagra...
