APPARATUS AND METHOD FOR PROVIDING REFORMED GAS WITH SOLID OXIDE FUEL CELL

摘要

PURPOSE: An apparatus for supplying reformed gas to a solid oxide fuel cell and a method thereof are provided to be able to rapidly and easily change the reformed gas, especially methane composition supplied to a solid oxide fuel cell, and to be able to stably control the temperature of a stack. CONSTITUTION: An apparatus for supplying reformed gas to a solid oxide fuel cell (300) comprises a backup reformer (230), a main reformer (250) connected to the backup reformer, a valve (100) branching a part of the gas supplied to the main reformer from the backup reformer to supply to the cathode of the solid oxide fuel cell. A method of supplying the reformed gas to the solid oxide fuel cell is to branch a part of the gas supplied to the main reformer from the backup reformer and to supply to the cathode of the solid oxide fuel cell.
