A seal structure of separator for fuel cell comprising:
two separators oppositely disposed with respect to one another, which have an electrode section, a manifold portion circulating fuel gas fed to said electrode portions, and a hole portion opposite to the manifold portions of the separators facing a passage grooves feeding fuel gas between said electrode portion and said manifold portion;
a seal body, which is provided integrally on said separators and has a first seal portion to seal an area surrounding said electrode, said passage groove and said manifold portion, and a second seal portion to independently seal said hole portion;
an electrolyte membrane, sandwiched between said two separators, having a size enough to include said electrode portion, said manifold portions and said hole portion, and having a shape with a through-hole on said manifold portion and at a position of said hole portion; and
a gasket surrounding said manifold portion of said separators and straddling said passage groove to enable fuel gas to be distributed. |
