(JP2000264603-A)   NOVELTY - Hydrogen generating apparatus comprises feeds for fuel, water and oxidant gas; a reforming catalyst; a catalyst heater; a carbon monoxide (CO) shifting catalyst; and a CO purification catalyst. The catalysts are placed in order from the fuel feed toward the downstream side. Fuel and water are fed to the heated reforming zone. Oxidant gas is mixed with both the reformed gas introduced to the shifting zone and the shift gas introduced to the purification zone. At least part of the reformed gas and the shifted gas are oxidized in the shifting and purification zones respectively.    USE - The apparatus is particularly useful as a source of hydrogen in fuel cells for domestic or vehicle use.    ADVANTAGE - The apparatus can be started and stopped frequently as the temperature of the catalysts stabilizes quickly. The apparatus is resistant to (i) the vigorous vibrations encountered in vehicle fuel cells and (ii) catalyst scatter between the different catalyst zones. The apparatus can be operated stably for an extended period of time.
