FUEL CELL, ITS MANUFACTURING METHOD, ELECTRODE FOR FUEL CELL AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a fuel cell small and lightweight enough to be used for a portable apparatus or the like and having high output density, to provide an electrode for a fuel cell, to provide their manufacturing methods, and to provide a battery pack.

SOLUTION: By attaching a fuel electrode-side collector 421 or an oxidizer electrode-side collector 423 to a substrate 104 or a substrate 110 of a fuel electrode 102 or an oxidizer electrode 108 of this fuel cell 100, the collector 421 or the collector 423 is thinned and reduced in weight to compose a structure without requiring an end plate or a binding component. A fuel or an oxidizer is directly fed to the surface of the collector 421 or the collector 423.
