PURPOSE:To recover the heat of reformed gas for lowering the temp. of the gas and to obtain reformed gas consisting principally of H2 with high heating efficiency by heating evaporated fuel which is passed through a reactor provided with a layer for passing reformed gas comprising porous ceramic to an outlet of the gas. CONSTITUTION:Methanol/water fuel mixture fed from a fuel feeding nozzle 2 is evaporated by directly heating a fuel evaporator 1 with a burner 3 of a fuel reforming device 30, and evaporated fuel is fed to plural reactors 4 erected vertically on the upper surface of the evaporator 1 along its annular periphery, which are constructed by supporting a catalyst layer 5 packed with pelletized catalyst with glass woll layers 13 at the top and the bottom of the catalyst layer 5. Simultaneously, the reactor 4 is heated by heating gas dispersed by a dispersing plate 12 provided with many through holes 12a having controlling function for heating. Thus, the evaporated fuel is converted at 150-500 deg.C to reformed gas consisting principally of H2. Then, the reformed gas is allowed to pass through a passing layer 15 for the reformed gas comprising porous ceramic being provided to an outlet at the top end of the reactor 4 to recover the heat of the reformed gas reducing the temp. of the gas and collecting in a collecting section 6, then the gas is fed as it is or through a miniaturized heat exchanger, to a main body of a fuel cell. |
