Abstract
A carbon monoxide reducing device supplies oxygen to a reformate gas obtained through a reforming reaction so as to oxidize carbon monoxide contained in the reformate gas by means of the oxygen and thereby reduces a concentration of carbon monoxide contained in the reformate gas. This carbon monoxide reducing device is equipped with an oxygen supply amount controller designed to oxidize CO. The oxygen supply amount controller controls an amount of oxygen supplied to oxidize carbon monoxide contained in the reformate gas based on an amount of supply of fuel contributing to the reforming reaction. Thereby, the amount of oxygen for oxidizing carbon monoxide contained in the reformate gas is adjusted appropriately, and a high-quality reformate gas can be obtained.
