ABSTRACT:
A fuel cell includes a plurality of fuel cell units. Each fuel cell unit includes an electrode assembly having electrodes and an electrolyte, a pair of separators, and gas sealing members. At least two of the fuel cell units include at least two electrode assemblies and at least three separators. In each of the separators, reaction gas communication ports are provided. In one of the separators of one of the stacked fuel cell units that is located at the end in a direction of stacking, through paths are formed. In one of the separators of one of the stacked fuel cell units that is located at the other end in the direction of stacking, reaction gas communication paths are formed. Both the through paths and the reaction gas communication paths are formed in all separators that are located between two fuel cell units that are located at the ends.
