摘要： PROBLEM TO BE SOLVED: To solve a problem where water produced in a cathode by a power generation reaction hinders diffusion and permeation of oxygen because of accumulating in a diffusion layer of the cathode, on a surface thereof and in slits of a collector plate and a fastening plate, whereby the cell voltage of a fuel cell and output density thereof are lowered, and a cell service life is shortened. SOLUTION: A hydrophilicity-imparting treatment is applied to a fuel cell surface to remove produced water of the cathode from the diffusion layer, and a hydrophilicity-imparting treatment is applied to a power generation system housing surface as well at the same time to increase the evaporation area of the produced water, whereby evaporation is facilitated.

摘要： PURPOSE:To greatly enhance the activity of an air electrode so as to significantly enhance the performance of a fuel cell having a hydrogen electrode and an air elec trode provided on both sides of a film of solid highpolymer electrolyte by making the water repellency of the hydrogen electrode higher than that of the air electrode. CONSTITUTION:A fuel cell comprises a hydrogen electrode 2 consisting of a catalyst layer 6 and a gas diffusion layer 7 with a film 1 of solid highpolymer electrolyte sandwiched therebetween, an oxygen electrode 3 consisting of a catalyst layer 8 and a gas diffusion layer 9, and a current collector 4 provided with several gas supply channels, and the end portion of each electrode 2, 3 is sealed by gas seals 5 to prevent gas leaks. Each of the catalyst layers is obtained by mixing and molding of an active component, a carbon carrier, a proton conductor and a water-repellent binding agent while the water repellency of the hydrogen electrode 2 is made higher than that of the oxygen electrode 3. Therefore, at the hydrogen electrode, electrode reactions in pores are accelerated, whereas at the oxygen electrode water is allowed to migrate easily and can readily be drained out of the system; so the gas diffusion properties of both of the electrodes are improved, resulting in enhancement of cell performance.
