ABSTRACT:
A fuel cell (100) which has an electrode-electrolyte joined article (101) composed of a fuel electrode (102), an oxidizing agent electrode (108) and, sandwiched thereby, a solid polymer electrolyte (114), characterized in that a separation film (330) comprising a material exhibiting an oxygen
itrogen separation factor of more than 1 is provided on the surface of an oxidizing agent electrode side current collector (110) constituting the oxidizing agent electrode (108). The fuel cell is a liquid fuel supply type of fuel cell which has a simple structure and also is capable of supplying satisfactory oxygen to an oxidizing agent electrode.
