Disclosed is a fuel cell (100) comprising a membrane-electrode assembly (10), channels (22, 32) arranged on both sides of the membrane-electrode assembly, and fluid permeable members (212, 312) respectively arranged between the membrane-electrode assembly and the channels. The heat resistance of the fluid permeable member on the anode side is lower than the heat resistance of the fluid permeable member on the cathode side. In this fuel cell, the heat flux in the fluid permeable member on the anode side is increased, while the heat flux in the fluid permeable member on the cathode side is decreased.
Cette invention concerne un pile à combustible (100) comprenant un ensemble membrane-électrode (10), des canaux (22, 32) ménagés sur les deux côtés de l'ensemble membrane-électrode, et des éléments perméables aux fluides (212, 312) respectivement ménagés entre l'ensemble membrane-électrode et les canaux. La résistance thermique de l'élément perméable aux fluides placé sur le côté anode est inférieure à la résistance thermique de l'élément perméable aux fluides placé sur le côté cathode. Dans cette pile à combustible, le flux thermique dans l'élément perméable aux fluides sur le côté anode est augmenté alors que le flux thermique dans l'élément perméable aux fluides sur le côté cathode est réduit.
