PROBLEM TO BE SOLVED: To effectively use hydrogen energy that was wasted as unnecessary gas, and eliminate requirement of facility and power for reforming raw fuel, by supplying gas generated in an activation reaction in a manufacturing process for activated carbon and using it for power generation. SOLUTION: Activation generated gas generated in an activation furnace 11 is guided through an impurity removing device 13 and a steam concentration adjuster 14 to a CO transformer 5 for CO transformation together with adequate steam. When CO concentration in fuel gas supplied to a fuel cell 1 is high, a cell characteristic of the fuel cell 1 is reduced. Therefore, CO in the activation generated gas and the steam are reacted in the CO transformer 5, to be transformed to carbon dioxide and water, and the CO concentration is reduced to lower than about 1%, for example. Such process is applied to the activation generated gas to produce fuel gas, the fuel gas is made to flow to a fuel electrode of the fuel cell 1, air guided through a blower is made to flow to an oxidant electrode, and power generation is performed. Generated power is direct power, therefore, is converted to alternating current by an inverter 15, and supplied to a load. |
