A porous body (28, 29) for a fuel cell (1000), a fuel cell component including the porous body and a method of manufacturing the fuel cell component is provided. The porosity in at least a portion (15) in the vicinity of the periphery of the porous body (28, 29) is lower than the porosity in an interior portion of the porous body. When a seal member (30) is arranged on the periphery of the porous body (28, 29) to be integrated with the porous body, the interior portion of the porous body (28, 29), is prevented from being impregnated with the seal member.
La présente invention concerne un corps poreux (28, 29) pour une pile à combustible (1000), un composant de pile à combustible comprenant le corps poreux et un procédé de fabrication du composant de pile à combustible. La porosité d'au moins une partie (15) à proximité de la périphérie du corps poreux (28, 29) est inférieure à la porosité dans une partie interne du corps poreux. Lorsqu'un élément d'étanchéité (30) est disposé sur la périphérie du corps poreux (28, 29) pour être intégré avec le corps poreux (28, 29), l'imprégnation de la partie interne du corps poreux (28, 29) par l'élément d'étanchéité est inhibée.
