ABSTRACT:
A solid polymer electrolyte fuel cell including a solid polymer electrolyte membrane, an anode side electrocatalyst electrode provided at one side of the polymer electrolyte membrane and an cathode side electrocatalyst electrode provided at the other side of the polymer, a membrane-like electrocatalyst layer permitting mass transfer therethrough provided at a boundary surface of an electrocatalyst layer for an oxygen reduction reaction in the polymer electrolyte membrane in the cathode side electrocatalyst electrode, and the membrane-like electrocatalyst layer including an electrocatalyst substance. A power generation efficiency can be remarkably improved with a simply structure and advantageous cost performance in the field of a solid polymer electrolyte fuel cell.
