An electrode for use in a fuel cell consists of a porous plastic substrate, a conductive layer and a catalyst layer, in which the substrate is hydrophilic. Preferably the substrate has a water wicking rate no less than 40 mm per 600 s. Such an electrode may be used in a fuel cell, with an electrolyte chamber (8) defined between two opposed electrodes (11, 12), the electrodes having the catalyst layers (5) facing away from the electrolyte in contact with respective gas chambers (7, 9). Preferably the electrolyte is maintained at a negative pressure during operation.

L'invention concerne une électrode destinée à être utilisée dans un pile à combustible consistant en un substrat de plastique poreux, une couche conductrice et une couche catalytique, dans laquelle le substrat est hydrophile. Le substrat possède, de préférence, un taux de drainage d'eau non inférieur à 40 mm par 600 sec. Une telle électrode peut être utilisée dans une pile à combustible, avec une chambre électrolytique (8) définie entre deux électrodes opposées (11, 12), les électrodes possédant des couches catalytiques (5) orientées à l'opposé de l'électrolyte en contact avec des chambres à gaz respectives (7, 9). L'électrolyte est, de préférence, maintenu à une pression négative durant son fonctionnement.
