Understanding and controlling the aging of the proton-conducting Nafion® membrane is one of the key points for the development of fuel cells. In collaboration with the Liten and ENSAM Paris, we have shown that the mechanism of hygrothermal aging, previously observed ex situ with a nude membrane, does not occur during fuel cell operation. Better yet, an aged Nafion® membrane can be rejuvenated by fuel cell operation.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
