PURPOSE:To prevent the leakage of the electrolyte so as to make a fused carbonate type fuel cell of high performance and long life time by producing a ultra fine particle layer on the interface of a gas diffusion electrode and a electrolytic plate by electrophoresis. CONSTITUTION:A gas diffusion electrode 2 made of nickel family metal on which a fine porous layer is to be produced is provided as a negative electrode in a solution 1, and an opposed electrode 3 made of stainless steel is provided as a positive electrode parallel to the gas diffusion electrode 2 and 10cm apart from the electrode 2. The solution is made by stirring well the distilled water solvent added with ultra fine nickel particle 4 to be adhered and positive ionic binder (cellulose family). On the surface of the ultra fine nickel particle 4 the positive ion 5 of the binder is adhered. In this state, when a DC voltage of 100V is applied between the nickel family metallic gas diffusion electrode 2 and the opposed electrode 3 from a DC constant voltage source 6 for 15sec to generate an uniform electric field, the ultra fine particle adhering the positive ion 5 on its surface is moved from the side of the positive opposed electrode 3 to the side of the negative nickel family metallic gas diffusion electrode 2 by the Coulomb's force, and ultimately adhered on the surface of the gas diffusion electrode 2. |
