Abstract:Based on the self-designed 100 kW fuel cell test bench,a test is carried out on the polarization curve,current density and single cell consistency of two types of proton exchange membrane fuel cell(PEMFC).A method to evaluate the single cell consistency is put forward.The test results show that there is a great difference between these two PEMFCs in their performances.When applied to automobile,the PEMFC has a better adaptability to the environment under higher pressure operation.
