    • A method of manufacturing an anode for solid oxide fuel cells is disclosed whereby the dispersion of nickel particles which form the anode for the solid oxide fuel cell is ensured, coherence of the Ni or NiO particles when being annealed or when generating electricity is prevented, the adhesion of the anode to the solid electrolyte layer is good, the contact resistance is reduced, and the electrode performance is improved.To form an anode on one surface of the central solid electrolyte layer, first, Ni or NiO, and a solution of an organometallic complex salt in an organic solvent, from which is obtained thin- films or minute particles of a solid electrolyte by thermal decomposition, are blended, and the solvent is evaporated until a suitable viscosity is obtained. The slurry obtained in this manner is coated onto the central solid electrolyte layer and this coated film is then dried, annealed, and thermally decomposed to obtain an NiO-solid-electrolyte or an Ni-solid-electrolyte cermet.
