Patent ID: 7175929

Claim:
A fuel cell, comprising: a membrane electrode assembly (MEA) including a polymer electrolyte membrane having first and second sides to which a fuel electrode and an air electrode are joined, respectively; a fuel electrode housing including a fuel channel and a fuel-side electrode film integrally formed on an internal face of the fuel electrode housing; and an air electrode housing having an air passage formed therein, the air electrode housing including an air-side electrode film integrally formed on an internal face of the air electrode housing, wherein: said fuel electrode housing is joined to said MEA with the internal face thereof facing the fuel electrode of said MEA so that the fuel-side electrode film is electrically connected to the fuel electrode; and said air electrode housing is joined to said MEA with the internal face thereof facing the air electrode of said MEA so that the air-side electrode film is electrically connected to the air electrode.
