Abstract

This disclosure proposes a proton exchange membrane fuel cell gas supply control system and method, aiming at the non-linearity, strong coupling, and poor traditional PID control effect of the hydrogen and oxygen partial pressure input control system of the proton exchange membrane fuel cell. The problem is that the combination of genetic algorithm and fuzzy control algorithm is used to optimize the PID parameters of the PID controller, which can effectively prevent the proton exchange membrane damage of the proton exchange membrane fuel cell, and improve the battery life shortening and overall efficiency.

Description

technical field [0001] The present disclosure relates to the technical field related to battery control, and in particular, relates to a gas supply control system and method for a proton exchange membrane fuel cell. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] In recent years, due to the rapid increase in the consumption of traditional fossil fuels and the increasingly serious environmental pollution problems, many countries have conducted large-scale research and implementation of renewable clean energy. my country has listed the renewable alternative energy - fuel cell as a key development frontier technology, and invested a lot of manpower, material and financial resources to carry out related research. As the fifth-generation fuel cell, proton exchange membrane fuel cell not only has the complementarity with wind energy and solar...
