Abstract

Each separator of a fuel cell stacked alternately with the power generation bodies has a first surface facing the first electrode of the power generation body, a second surface facing the second electrode of another power generation body, a first reactant gas channel that supplies or discharges a first reactant gas to or from the first electrode and that extends in the separator and has an opening portion opened in the first surface, and a second reactant gas channel that supplies and discharges a second reactant gas to or from the second electrode facing the second surface and that extends in the separator and has an opening portion opened in the second surface. The opening portion of the first reactant gas channel and the opening portion of the second reactant gas channel are both disposed along a first portion of a peripheral border of a power generation region.

First claim

The invention claimed is:

1. A fuel cell comprising:
power generation bodies each having a first electrode and a second electrode; and
a plurality of separators stacked alternately with the power generation bodies so as to constitute the fuel cell, each separator including:
a first surface that faces the first electrode of one of the power generation bodies;
a second surface that faces the second electrode of another one of the power generation bodies;
at least one first r…
