Title (EN) MANUFACTURING PROCESS FOR FUEL CELL, AND FUEL CELL APPARATUS
(FR) PROCEDE DE FABRICATION DE PILE A COMBUSTIBLE, ET APPAREIL A PILE A COMBUSTIBLE
Abstract: front page image
(EN)In a manufacturing process for a fuel cell having a fuel electrode, an oxidizer electrode, and a polymer electrolyte membrane held between both the electrodes, and having electrode catalyst layers which are individually provided between both the electrodes and the polymer electrolyte membrane, the process has the step of ejecting an electrode catalyst composition containing conductive particles carrying thereon at least a catalyst, by an ink-jet process to form the electrode catalyst layers. This provides a fuel cell manufacturing process which can accurately control the coverage of catalyst layers and also can simply provide pores while controlling the same.
(FR)L'invention concerne un procédé de fabrication d'une pile à combustible possédant une électrode combustible, une électrode oxydante, et une membrane d'électrolyte polymère maintenue entre les deux électrodes, et possédant des couches catalysantes pour les électrodes qui sont placées de façon individuelle entre les deux électrodes et la membrane d'électrolyte polymère. Ce procédé comprend l'étape d'éjection d'une composition catalysante pour l'électrode contenant des particules conductrices renfermant au moins un catalyseur, au moyen d'un procédé à jet d'encre afin de former des couches catalysantes pour l'électrode. Ceci produit un procédé de fabrication de pile à combustible pouvant réguler de façon appropriée la couverture des couches catalysantes et pouvant également fournir de façon simple des ports, tout en les régulant.
