<P>PROBLEM TO BE SOLVED: To solve the problem that, when compared with an inside reformation type fuel cell, the portability of an outside reformation type portable fuel cell that utilizes methanol is hindered by a reforming device though it is efficient. <P>SOLUTION: On the fuel cell system including a methanol oxidation type steam reforming device, the methanol reformation at the outside of the fuel cell is carried out by setting a reformation temperature for restraining the generation of CO to 180 to 250°C, and reformation of steam and oxidation of CO are simultaneously proceeded in a reforming catalyst by mixing air in reformed gas. The quantity of the fuel and the air to be supplied to the fuel cell is controlled only by a pressurized air. The efficiency of the reformation is improved and starting period is shortened by heating the catalyst directly. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
