Abstract
An adhesion layer containing a second solid polymer electrolyte is disposed between a solid polymer electrolyte membrane and a fuel electrode and/or an oxidant electrode containing a first solid polymer electrolyte and a catalyst substance. The solid polymer electrolyte membrane and the adhesion layer are made of the same solid polymer electrolyte. In this manner, the adhesion at the interface between the electrode surface and the solid polymer electrolyte membrane is enhanced to implement the elevation of the cell characteristics and the elevation of the reliability of the cell.
