In order to provide a constituting part for a fuel battery in which a number of steps of assembling the constituting parts for the fuel battery can be reduced, and in which a replacing property and a maintenance property of fuel battery cell parts can be improved and a cost for parts can be reduced, the structure is made such that a separator made of a carbon plate or the like, a gas diffusion layer made of a carbon fiber or the like, and a gasket made of a liquid rubber cured material or the like are integrally formed, and further, gaskets are respectively provided on both surfaces of a pair of gas diffusion layers holding an independent electrolyte membrane from both sides thereof between the pair.

L'invention concerne un composant d'une pile à combustible permettant de réduire l'heure-personne nécessaire pour l'assemblage d'un composant pour une pile à combustible. Le remplacement et l'entretien d'un composant d'une pile à combustible sont améliorés et le coût du composant est réduit. Le séparateur composé d'une plaque de carbone, la couche de diffusion gazeuse en fibres de carbone et le joint d'étanchéité statique en un matériau de caoutchouc liquide durci forment une seule pièce. Des joints d'étanchéité statiques sont placés sur les deux côtés d'une paire de couches de diffusion gazeuse, prenant en sandwich un film séparé d'électrolyte.
