PURPOSE:To improve the generating performance by splitting a catalyst layer applied on each electrode of an unit cell discontinuously thereby uniforming the thickness of the catalyst layer. CONSTITUTION:An electrolyte layer 5 is held between a fuel electrode formed with a gas flow path on one face of an electrode basic materil 1 having high conductivity and easy gas diffusion while provided with a catalyst layer 2 having uniform thickness on the other face and an oxide electrode to form an unit cell. A plurality of unit cells and separators 6 are laminated alternatively to form a fuel cell. When arranging a guide 7 on the basic material 1 while developing catalyst compound 9 through a doctor blade 8, the catalyst layer 2 having uniform thickness can be obtained. Furthermore it can be standardized such that the guide 7 is made into a sheet and the catalyst layer 2 is punched and the punching speed is increased. In such a manner the thickness of the catalyst layer to be applied on the electrode can be uniformed to improve the cell performance. |
