The final part of this paper summarizes the established PEMFC water condensation rate model, which simulates the water transfer process in the gas diffusion layer from the comparison of the cooling water evaporation ratio and the water content used in the condensation rate. The experimental value, Fluent value and water condensation rate model value under different experimental conditions are compared and analyzed, which improves the accuracy of software simulation. The water condensation rate model has a guiding significance for the optimal design of water management under different current densities, and can effectively avoid the problems of fuel cell water injection or dehydration. more specifically. The calculated results are consistent with the experimental results.

The last part of this paper summarizes the established PEMFC water condensation rate model, which simulates the water transfer process in the gas diffusion layer from the ratio of evaporation of cooling water and the water content used in the condensation rate.
