Abstract: Service life is the major issue which limits the commercialization of proton exchange membrane fuel cell (PEMFC). The complex driving conditions of vehicles accelerate the aging of fuel cell, therefore a comprehensive understanding of the performance degradation mechanism of PEMFC is needed in various driving conditions to facilitate its commercialization. This paper mainly discusses the background and advances of the related research on startup-shutdown conditions, analyzes the gas distribution of fuel cell in startup-shutdown process, and summarizes the main mechanisms leading to the performance degradation of fuel cell. Finally, this article introduces mitigation strategies for startup-shutdown conditions, including material improvement and system control, for solving the PEMFC performance degradation problem and improving fuel cell lifetime.
