description The invention discloses a high-power proton exchange membrane fuel cell stack temperature two-dimensional characterization method, which comprises the following steps: constructing a stack single cell air domain simplified model, and carrying out model fitting on single cell air domain pressure drop; constructing a stack fluid domain simplified model, and solving the air flow of each single cell of the stack; establishing a fuel cell heat production theoretical model, and solving the heating value of a single cell in the stack; and constructing a two-dimensional simplified model of the stack, and solving the overall temperature distribution of the stack. According to the high-power proton exchange membrane fuel cell stack temperature characterization method provided by the invention, corresponding simulation parameters can be corrected and modified through tests, and the method is suitable for high-power stacks adopting bipolar plates and membrane electrode assemblies of different specifications and has diffe
