Patent ID: 8679692

Claim:
A fuel cell comprising: an electrochemical device portion in which power generation is performed by a chemical reaction; a radiation member disposed at a position in contact with outside air and provided with radiation fins for radiating heat generated in the electrochemical device portion, at least one of the radiation fins having a curved thinning profile in a direction away from the electrochemical device portion; and a conductive member for exchanging a current generated in the electrochemical device portion with the outside, wherein the electrochemical device portion is disposed with a space from another electrochemical device portion or forms a pair of two electrochemical device portions provided adjacent to each other so that the pair is disposed with a space from another electrochemical device portion or another pair, the conductive member includes a first surface disposed in contact with the electrochemical device portion and a second surface opposite the first surface and in contact with outside air, at least one inlet hole is provided in the conductive member in order to pass air to the electrochemical device portion, and the radiation member is provided in contact with the second surface of the conductive member, or part or the whole of the radiation fins are formed on at least a portion of the second surface of the conductive member.
