Simulation Analysis and Test Validation of Fuel Cell System

The fuel cell system includes stack,air subsystem,hydrogen subsystem,cooling subsystem, involving many components. Therefore,in the early stage of research and development,establishment of a fuel cell system model through system simulation has a guiding role for system development. Firstly,based on the test results and characteristic parameters of components,virtual calibration of components is carried out to establish an accu⁃ rate component model. Then,according to the system flow chart,a complete fuel cell system simulation model is built. Finally,key output performance parameters of the system are evaluated and predicted through simulation cal⁃ culation. Comparing the simulation results with the test data,the results show that the maximum average absolute percentage error between the model simulation results and the test data is 4.33%,with a high degree of consistency. It is verified that the simulation model has a high accuracy and can be used to study the performance of the fuel cell system,which has great guiding significance for future research and development of the fuel cell system. © 2023 SAE-China.
