Performance Degradation and Life Prediction of Proton Exchange Membrane Fuel Cell

In order to reduce the air pollution caused by automobile exhaust emissions, the proton exchange membrane fuel cell (PEMFC) is more and more widely used in automobile field. While the durability is an important reason hindering the development of fuel cell. In order to popularize the use of PEMFC, it is important to improve durability and prolong service life of PEMFC. Based on the working mechanism of PEMFC and the analysis of durability test conditions, methods and health indicators, this paper compares the durability test data of fuel cells under three different working conditions, analyzes the influence of different working conditions on performance degradation of fuel cells, and discusses the reasons for different performance degradation laws. Finally, the advantages and disadvantages of fuel cell life prediction algorithms are summarized.
