Patent ID: 8202665

Claim:
A fuel cell apparatus comprising: at least one fuel cell stack including a plurality of unit fuel cells; a casing having an inner wall, said casing being arranged and configured to accommodate the at least one fuel cell stack; and means for absorbing vibrations transmitted to the at least one fuel cell stack via the casing in such a way as to prevent torsion and bending deformation of the casing and the at least one fuel cell stack, wherein each of the plurality of unit fuel cells includes: a membrane electrode assembly including an electrolyte membrane and electrodes arranged on the electrolyte membrane; and a pair of separators sandwiching the membrane electrode assembly, wherein the vibrations absorbing means includes elastic members arranged on and protruding from the periphery of the pair of separators, the elastic members contacting with the inner wall of the casing, wherein each of the separators has a polygonal shape defined by a plurality of sides, and each of the elastic members has an inner part on a plane of the corresponding, one of the pair of separators and an outer part that covers a portion of a peripheral edge of the corresponding one separator.
