Patent ID: 7846612

Claim:
A fuel cell comprising: an electrolyte electrode assembly including a pair of electrodes and an electrolyte interposed between said electrodes; first and second separators for sandwiching said electrolyte electrode assembly; and first and second insulating positioning members, wherein: said first separator has a first positioning hole, and said second separator has a second positioning hole; said first insulating positioning member is attached to said first positioning hole, and said second insulating positioning member is attached to said second positioning hole; a first wall of said first insulating positioning member, which faces toward said first positioning hole, is fitted to a second wall of said second insulating positioning member, which faces toward said electrolyte electrode assembly, for positioning said first and second separators such that said first and second separators are insulated from each other; said first insulating positioning member includes a support section for supporting one surface of said first separator, and a section defining said first wall; and said second insulating positioning member includes a support section for supporting one surface of said second separator, a first section fitted to said second positioning hole and a second section defining said second wall, said second section protruding oppositely to said first section; a first ring-shaped support member for supporting the other surface of said first separator, said first ring-shaped support member being fitted to said first insulating positioning member; and a second ring-shaped support member for supporting the other surface of said second separator, said second ring-shaped support member being fitted to said second insulating positioning member.
