Abstract

Selon l'état antérieur de la technique, une pile à combustible méthanol directe comporte au moins une unité de pile à combustible composée d'une unité d'électrode à membrane, et un réservoir de méthanol. Selon l'invention, la chambre d'anode comporte ou est remplacée par des structures et/ou des matériaux à effet capillaire éliminant tout volume mort. Le procédé d'utilisation selon l'invention consiste à prolonger brièvement l'exploitation de l'unité de pile à combustible avec soupape à CO2 fermée, après coupure de la batterie de piles à combustible, de manière que le mélange méthanol/eau se trouvant dans la chambre d'anode est repoussé dans le réservoir.
