Abstract

L'invention concerne une unité membrane-électrodes pour pile à combustible, qui comprend une anode éventuellement recouverte d'un catalyseur, une cathode éventuellement recouverte d'un catalyseur et un conducteur de protons situé entre l'anode et la cathode. Le conducteur de protons est formé par un non-tissé à base de microfibres qui est imprégné d'un électrolyte jusqu'à saturation. A des températures allant jusqu'à +200 ·C, ainsi que dans des conditions d'oxydation et de réduction, le non-tissé est chimiquement inerte par rapport à l'électrolyte. Le non-tissé pèse entre 20 et 200 g/m?2¿ et son épaisseur est inférieure à 1 mm et le volume poreux se situe entre 65 et 72 %.
