Abstract: Problem: To suppress the occurrence of damage to fuel cell units caused by oxidation shrinkage of fuel electrodes. Solution Means: The invention is a solid oxide fuel cell for generating electricity by reacting hydrogen and oxidant gas in individual fuel cell units, wherein the individual fuel cell units comprise a fuel electrode, an oxidant gas electrode, and a solid electrolyte erected between fuel electrode and oxidant gas electrode; the fuel electrode comprises a composite material containing nickel, and the solid oxide fuel cell prevents shrinkage due to oxidation of the fuel electrode by maintaining the fuel electrode in an oxygen-free atmosphere until the temperature of the fuel electrode has dropped to 350° C. after electrical generation is stopped.
