Development of Highly Durable MEA for PEMFC under High Temperature Operations (2)

Abstract

With regards to perfluorinated polymer based MEAs for PEMFC, the world's first highly durable MEA under high temperature and low humidity operations has been developed. The newly developed MEA, which uses a new perfluorinated ion-exchange polymer composite (NPC), reduces the degradation rate by 1/100 - 1/1000 compared to the conventional MEA. The NPC MEA can be operated for more than 4,000 hours at 120 ºC and 50% relative humidity. This paper reports on the performance of the NPC MEA under high temperature and low humidity conditions.
