Patent ID: 7906247

Claim:
A fuel cell, comprising: a membrane electrode assembly which comprises electrodes being formed on the surface of an electrolyte layer, the membrane electrode assembly having four peripheral edge portions including a first pair of short opposing peripheral edge portions and a second pair of long opposing peripheral edge portions; insulating frames which are disposed at the front and the rear surface of the membrane electrode assembly, and which fix the membrane electrode assembly by sandwiching only the first pair of short opposing peripheral edge portions of the membrane electrode assembly, thereby leaving at least a second the second pair of long peripheral edge portions not sandwiched by the frames; and electrically conductive separators which are disposed at the front and the rear surface of the membrane electrode assembly, which are formed at the second pair of long opposing peripheral edge portions of the membrane electrode assembly not sandwiched by the insulating frames, and which contact against the membrane electrode assembly and define collector portions that collect electricity from the membrane electrode assembly.
