Abstract
A fuel cell includes an electrolyte membrane, a first electrode, a second electrode and a stress suppressing structure. The first electrode is joined to one surface of the electrolyte membrane. The second electrode is joined to an other surface of the electrolyte membrane. The first peripheral section which is at least part of periphery of the first electrode is located on an inner side along a planar direction of the first electrode than respective peripheries of the electrolyte membrane and the second electrode. The stress suppressing structure is configured to suppress concentration of stress on a location along the first peripheral section in the electrolyte membrane.
