Abstract:
1. A solid oxide fuel cell system for generating electricity by reacting fuel and oxidation gas, comprising: a fuel cell module comprising multiple solid oxide fuel cell units which is thermally prepared for generation of electricity through a series of startup operations comprising an auto-thermal reforming reaction (ATR) operation and a steam reforming reaction (SR) operation performed after the ATR operation, wherein the SR operation comprises a first steam reforming reaction (SR a fuel supply device that supplies fuel used to generate electricity; a reformer that reforms fuel supplied from the fuel supply device and supplies the reformed fuel to the solid oxide fuel cell units, wherein the reformer is heated by burning fuel left unused for generation of electricity in the solid oxide fuel cell units; a water supply device that supplies water to the reformer; an electricity generation oxidation gas supply device that supplies oxidation gas for electricity generation to the solid oxide fuel cell units; and a controller programed to control the fuel supply device and the water supply device during the startup operations in order to thermally prepare the solid oxide fuel cell units in the fuel cell module for generation of electricity, wherein the controller is programed to control the fuel supply device to raise a temperature of the solid oxide fuel cell units during the SR
