Abstract
In this paper, a dynamic model of PEMFC is developed to estimate the dynamic performance of PEMFC by analyzing in detail the influence factors of voltage of PEMFC including various losses. The partial pressure of hydrogen and oxygen is obtained using the differential form of the ideal-gas equation in this model. The steady-state model is obtained by setting reasonable parameter values. The simulation results and experimental results have good consistency, which shows that the simulation model is correct, reasonable and effective. It analyzed the dynamic response characteristics of the output voltage and the partial pressure of hydrogen in condition of load mutations using the simulation mode in this paper. The dynamic model of PEMFC proposed in this paper can accurately simulates the performance of practical fuel cell system, evaluate the load capacity of fuel cell and have guiding significance for the fuel cell operation.
