Abstract:
A fuel cell stack seal structure of a fuel cell stack, the fuel cell stack including a plurality of fuel cell single cells that are stacked, each of the fuel cell single cells including a membrane electrode assembly and a pair of separators holding the membrane electrode assembly between the pair of separators, includes inner peripheral sealing members and an outer peripheral sealing member at peripheral edges of a pair of separators, in which the inner peripheral sealing members close a gap between inner peripheral ribs that protrude at least towards a mutually facing sides of the pair of separators, and the outer peripheral sealing member that closes a gap between outer peripheral ribs that protrude at least towards the mutually facing sides of the pair of separators. The inner peripheral sealing members and the outer peripheral sealing member form a first closed space between the inner peripheral sealing members and the outer peripheral sealing member. The outer peripheral sealing member has a notch that communicates the first closed space with the outside.

Claim (Index 32):
The fuel cell stack sealing structure according to  claim 20 , further comprising:\n a second inner peripheral sealing member that closes a gap between peripheral edges of the fuel cell single cells: and a second outer peripheral sealing member that is disposed at an outer side of the second inner peripheral sealing member to close the gap between the peripheral edges of the fuel cell single cells, wherein a second closed space is formed between the second inner peripheral sealing member and the second outer peripheral sealing member, and the second outer peripheral sealing member has a notch that communicates the second closed space with the outside.
