Proton Exchange Membrane Fuel Cell Ejector Test Platform Design and Ejector Test Analysis

The hydrogen recirculation system is essential to the performance of fuel cell system; ejector device plays an important role in system. In this paper, a test platform which can simulate anode integrated for testing. Based on platform, was tested under different operating conditions. design method and process are introduced detail. results compared with Computational Fluid Dynamics (CFD) simulation turbulence models. show that standard k-e model more accurate than other models at small medium flow rates. At large rate, realizable has higher accuracy
