PURPOSE:To increase system efficiency by installing a combustion furnace which burns excess fuel of a fuel cell and compressed air supply equipment which is driven by exhaust gas of the combustion furnace and excess air of the fuel cell. CONSTITUTION:By-product hydrogen generated in a chemical plant is supplied to a fuel electrode 1a of a fuel electrode main body 1 through a supply line 2. Excess fuel exhaust from the fuel electrode is supplied to a combustion furnace 10 through an excess fuel line 3. As air required to the combustion furnace 10, a part of air supplied from a compressor 11 is supplied through a supply line 12. Exhast gas in the combustion furnace is supplied to a turbine 11a of a turbo- compressor 11 with excess air of the fuel cell through an excess air line. A compressor 11b having the same axis with the turbine 11a is driven and compressed air is supplied from the compressor 11b. Most of the compressed air is supplied to an air electrode 1a of the fuel cell 1 through an air supply line 4 and a part of the compressed air is used in the combustion furnace 10. |
