Abstract
A fuel cell is provided that has a sufficient sealing performance while having a restrained dimension in the stacking direction thereof. The fuel cell is formed by stacking a plurality of fuel cell units, each fuel cell unit comprising: an electrode assembly formed by disposing electrodes on both sides of an electrolyte; a pair of separators that sandwich the electrode assembly in the thickness direction thereof; and gas sealing members that are disposed at an outer peripheral portion of the electrode assembly, and that seal respective reaction gas flow passages that are formed between each separator and the electrode assembly and are bounded by the separators and electrode assembly. In each of the separators, there are provided reaction gas communication ports that are provided outward from the gas sealing members, in one separator, through paths are formed that penetrate the separator in the thickness direction thereof and connect the reaction gas communication ports with the reaction gas flow passages, and in the other separator, reaction gas communication paths are formed that detour around the gas sealing member in the thickness direction of the separator and connect the reaction gas communication ports with the reaction gas flow passages.
