It is possible to provide a fuel cell plate member capable of effectively preventing degradation caused by a fluid. The fuel cell plate member is layered together with a film/electrode complex to constitute a fuel cell formed by a plurality of single cells. The fuel cell plate member has a fluid channel forming portion to form a fluid channel for supplying and discharging a fluid to/from the film/electrode complex and/or between cells. The fuel cell plate member includes a first coating portion for coating the fluid forming portion and a second coating portion for coating the end portion of the first coating portion together with the portion in the vicinity of the end portion of the first coating portion.

Il est possible de fournir un élément de plaque de pile à combustible pouvant empêcher de manière efficace la dégradation provoquée par un fluide. L'élément de plaque de pile à combustible est disposé en couches conjointement à un complexe film/électrode pour constituer une pile à combustible formée par plusieurs cellules individuelles. L'élément de plaque de pile à combustible est pourvu d'une partie de formation de canal fluidique qui forme un canal fluidique pour alimenter et décharger le fluide compris dans un complexe film/électrode et/ou dans l'espace situé entre les cellules. L'élément de plaque de pile à combustible comporte une première partie de revêtement permettant d'appliquer un revêtement sur la partie de formation fluidique et une seconde partie de revêtement permettant d'appliquer un revêtement sur la partie d'extrémité de la première partie de revêtement conjointement à la partie située à proximité de la partie d'extrémité de la première partie de revêtement.
