Abstract This study performed a continuous durability evaluation experiments on the proton exchange membrane (PEM) water electrolysis system. The dynamic characteristics of the system caused by the durability reduction was analyzed. A stack deterioration experiment was conducted by measuring the voltage change under a constant current conditions at the operating temperature. The water electrolysis stack durability data for long-term operation obtained through this study showed that performance decreased by about 18% during about 1,500 hours of operation. As a results, the durability of the stack rapidly decreased, and the power consumption of the stack increased on the dynamic simulation for PEM water electrolysis system.
