A method of manufacture of an electrode for a fuel cell, the method comprising at least the steps of: (a) providing an electrode substrate; (b) contacting at least a part of the electrode substrate with an electroless plating solution comprising a re-ducing agent, a metal precursor and a suspension of particulate material; and (c) electrolessly plating the metal from the metal pre-cursor onto the contacted part of the electrode substrate, thereby co- depositing the particulate material on the contacted part of the electrode substrate to provide the electrode.

L'invention porte sur un procédé de fabrication d'une électrode pour une pile à combustible, le procédé consistant : (a) à se procurer un substrat d'électrode, (b) à mettre au contact au moins une partie du substrat d'électrode avec une solution de dépôt autocatalytique comportant un agent réducteur, un précurseur de métal et une suspension de matières particulaires ; et (c) à déposer de manière autocatalytique le métal à partir du précurseur de métal sur la partie en contact du substrat d'électrode, co-déposant ainsi la matière particulaire sur la partie en contact du substrat d'électrode pour fournir l'électrode.
