<P>PROBLEM TO BE SOLVED: To suppress decrease of a seal property due to deformation of an seal member at the time of supply of a reactant gas in a fuel cell stack. <P>SOLUTION: A fuel cell module 40 is constructed by stacking a plurality of membrane electrode assembly units with intervention of a separator 42, the membrane electrode assembly units having a seal gasket 410 around membrane electrode assemblies (411m, 411a, 411c). The separator 42 is provided with a plurality of through-holes (e.g., a through-hole 424i for hydrogen supply, a through-hole 424o for anode off-gas ejection) for flowing a reactant gas or the like made available for electric power generation in the membrane electrode assemblies in a thickness direction of the separator 42, and a seal member 428 for sealing a reactant gas or the like is bonded around the through-hole on a surface of the separator 42 by bringing it into butt-contact with the other separator 42 adjoining it across the membrane electrode assembly unit. <P>COPYRIGHT: (C)2008,JPO&INPIT |
