Abstract
A fuel cell is provided that prevents destabilization of power generation due to heat generated in an electrochemical device portion. In a fuel cell having a membrane-electrode assembly which performs power generation by chemical reaction, a membrane-electrode assembly is disposed with a space from another membrane-electrode assembly or two membrane-electrode assemblies are provided adjacent to each other so that the pair is disposed with a space from another membrane-electrode assembly or another pair, and one of the main surfaces of a membrane-electrode assembly is in contact with outside air. Conductive plates are disposed in contact with the membrane-electrode assembly in order to exchange a current generated in the membrane-electrode assembly with the outside, and radiation fins are provided on the conductive plate on the main surface side in contact with outside air so that the conductive plate serves as a radiation member.
