SMALL FUEL CELL, ITS MANUFACTURING METHOD, AND SMALL FUEL CELL SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a small fuel cell wherein a power generating part can be uniformly heated and cells can be properly connected.

SOLUTION: A pair of a fuel electrode 11 and an air electrode 12 which composes cells are formed on the surface of an electrolyte film 20 with a narrow gap kept between. These cells are connected in series through a lead wire 14, and a negative potential terminal 18 and a positive potential terminal 19 are connected to the cells at both ends. The surface of the electrolyte film 20 is coated with a resin sheet 17 in which an outer wall 16 forming a fuel passage 13 and an air intake 15 are formed. A resistance film 21 to heat the electrolyte film 20 is formed on the rear surface of the electrolyte film 20, and the resistance film is covered with a protective resin film 22 to protect the electrolyte film 20 and the resistance film 21.
