PROBLEM TO BE SOLVED: To make manufacturing possible for a solid electrolte fuel cell having excellent characteristics by forming an anode layer excellent in the catalyst activeness using the plasma fusion spray method which can work well with introduction of a large-sized cell. SOLUTION: A binder is added to NiO having a particle size under 1μm and YSZ having particle sizes under 1μm and also around several tens of μms, followed by well mixing and drying in the atmosphere at a room temp. The obtained material is screened by a mesh of 5-6 mm, followed by provisional shaping at approx. 10<8> Pa and crushing, and the resultant is screened by a mesh of 106μm, followed by a two-hr provisional baking process at 1300 deg.C. The obtained powder is crushed and classified to 45-106μm so that a NiO-YSZ powder is prepared. This Nip-YSZ powder is subjected to a plasma fusion spray and deposited on a base board or an electrolyte layer with a low plasma input using a plasma gas of Ar and H2 of a low rate of flow, and thus an anode layer is formed. |
