| 摘要 |
A solid oxide fuel cell system (A1, A2, A3) is provided with solid oxide fuel cell (20) that generates electric power by separating from each other and circulating an anode gas and a cathode gas at an anode (21) and cathode (22) that are stacked on the two sides of an electrolyte membrane (23) and with a startup combustor (12) that generates high temperature combustion gas for raising the temperature of the solid oxide fuel cell (20). When the temperature of the solid oxide fuel cell (20) is determined to be a prescribed temperature (Tf) or less, restarting is carried out by the cathode gas that is supplied to the cathode (21) being supplied to the startup combustor (12). |
