Abstract
Each of the fuel cell units making up a fuel cell stack includes a first separator, a second separator, and a third separator. A predetermined number of load receivers are provided integrally on outer ends of the first separator, the second separator, and the third separator. The load receivers of the second separator protrude toward the casing beyond the other load receivers. Resin clips are inserted into the load receivers, such that the first separator, the second separator, and the third separator are fixed together by the resin clips.
Claims7
A fuel cell stack formed by stacking fuel cells each including an electrolyte electrode assembly and separators, said electrolyte electrode assembly including a pair of electrodes and an electrolyte interposed between said electrodes, said fuel cell stack comprising:
- a positioning mechanism for positioning the separators in alignment;
- a connecting member separate and distinct from the positioning mechanism for fixing said separators together in a stacking direction;
- and
- a resin guide section separate and distinct from the connecting member and provided on and extending outwardly from a peripheral outer end of at least one of said separators in a direction perpendicular to the stacking direction, wherein the resin guide section comprises a hole extending in the stacking direction for insertion of an insulating clip forming said connecting member, the resin guide section protruding outwardly beyond outer ends of other ones of the separators for receiving an external load.
