The present invention provides a solid electrolyte type fuel cell that can control a cross-over, and implements the high fuel efficiency and the high output of the fuel cell. A substance is dissolved to a fuel 124, and does not permeate a solid polymeric electrolyte film 114. Because of this, on an interface between the solid polymeric electrolyte film 114 and the fuel 124 in a fuel electrode 102, an osmotic pressure in a direction from an oxide agent electrode 108 to a fuel electrode 102 is generated. Because of this, the water movement from the fuel electrode 102 side to the oxidizing agent electrode 108 side is controlled, and the cross-over of the fuel is controllable.

A liquid fuel for a fuel cell comprises an organic compound and at least one kind of anti foaming agent. A catalyst electrode is capable of, when used for a fuel cell, increasing in an effective surface area of a fuel electrode and increasing in an output power of the fuel cell, by suppressing adsorption onto the surface of the electrode of an air which is a by-product produced at the fuel electrode as well as by quickly removing the foamed air which is once adsorbed thereto.

An adhesive layer 3 is disposed between a carbon particle 2 and a catalyst substance 1 of a catalyst-supporting particle for a fuel cell containing the carbon particle 2 and the catalyst substance 1. Thereby, the catalyst-supporting particle for fuel cell can be obtained in which a contact resistance between the catalyst substance and the carbon particle supporting the same is lower, and the aggregation of the catalyst substance is suppressed. A catalyst electrode for a fuel cell and the fuel cell using the above particle have a higher output power and an excellent durability.
