Abstract:

In order to assist the development of the fuel cell test system and the regulation of operating parameters, it is necessary to construct a system simulation model to optimize the matching of key parameters and analyze and evaluate the performance of the system, so as to formulate the control strategy of the fuel cell test system and improve the performance and reliability of the system. The key components were determined according to the topological structure of the fuel cell stack test bench, component models were established and simulation models of the fuel cell test system were built, and parameters of each component in the system model were calibrated according to the experimental requirements. The output results of key performance parameters in the test system were predicted and evaluated by simulation, and the simulation results were compared with the actual test data. The results show that the experimental data of the fuel cell test system is in high agreement with the simulation results of the established model, and the calculated average absolute percentage error of each parameter index of the fuel cell is 3.65% at most. The model can be used for the performance research of the fuel cell test bench and the optimization of control strategy. It provides an effective simulation tool support for developing test system and improving dynamic response performance of fuel cell.
