<P>PROBLEM TO BE SOLVED: To provide a fuel cell system using dimethyl ether as fuel which uses fuel having dimethyl ether as a main component and in which down-sizing and high power generation efficiency can be attained compatibly. <P>SOLUTION: The fuel cell system using dimethyl ether as fuel comprises a reforming reactor 6 for reforming the fuel having dimethyl ether as a main component, a carbon monoxide conversion reactor 10 for reducing the concentration of a carbon monoxide gas, and a solid polymer type fuel cell 14 for carrying out the power generation reaction of a fuel cell. In the reforming reactor 6, the fuel reacts with water vapor and is reformed into a reformed fuel gas with the high concentration of a hydrogen gas, and the reformed gas is introduced into the carbon monoxide conversion reactor 10 and the concentration of a carbon monoxide contained in the reformed fuel gas is reduced; and in a range from the exit of the reforming reactor 6 to the inside of the carbon monoxide conversion reactor 10, water is added into the reformed fuel gas, and by the amount of water added, the carbon monoxide conversion reaction in the carbon monoxide conversion reactor 10 is controlled. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
