Fuel cell performance in liquid feed fuel cells with an electrode comprising a carbonaceous substrate and an electrocatalyst can be increased by oxidizing the carbon substrate, particularly by electrochemical methods in acidic aqueous solution, prior to incorporation of the electrocatalyst. The treated substrate may thereafter be advantageously impregnated with a proton conducting ionomer to prevent excessive penetration of the applied catalyst into the substrate. The treatment method is particularly effective for direct methanol fuel cell anodes.
L'invention concerne l'amélioration des performances de piles à combustible à charge liquide dotées d'une électrode comprenant un substrat carboné et un électrocatalyseur, par oxydation du substrat de carbone, notamment par des procédés électrochimiques dans une solution aqueuse acide, avant l'incorporation de l'électrocatalyseur. On peut ensuite avantageusement imprégner le substrat traité avec un ionomère conducteur de protons pour empêcher une pénétration excessive du catalyseur appliqué dans le substrat. Le procédé de traitement est particulièrement efficace pour des anodes de pile directe méthanol-combustible.
