PURPOSE:To improve gas-sealing ability and collector method without occurrence of a junction defect between coatings, a warp due to large area, a shortage of strength or the like by forming sprayed coatings of a fuel electrode, an electrolyte, an air electrode or the like with the use of a masking plate provided with a slit formed in the shape of an unfolded fan. CONSTITUTION:The sectional form of the slit 5 of a masking plate 6 is made in the taper form of an unfolded fan foward the side of substrate 4 and at the same time blasting treatment is applied to the under surface of the masking plate and thus a power generating element is formed by thermal spraying with the use of the masking plate as a mask. In this way, a fuel electrode, electrolyte, an air electrode or the like are formed, so that the variation of coating thickness on the edge of each sprayed coating 21 of the fuel electrode or the like becomes gently-sloping and thus the peeling- off of the sprayed coating can be prevented. And the blasting treatment is applied to the under surface of the masking plate 6 and at the same time the thermal spraying is carried out at a close distance between the substrate 4 and the masking plate, so that spray particles follow the arrow mark and become easy to stick to the blasting treatment surface 23 and thus the contamination of particles caught by the masking portion can be prevented. |
