NOVELTY - The fuel reformer has a catalyst space (3) with discharge port (2) for discharging a liquid raw material (11) containing hydrocarbon compound. The inner wall face of the catalyst space is filled with the liquid raw material, and the pressure in the raw material holding space (2A) is increased rapidly, using a heater (9). The heater makes the catalyst space discharge the held liquid raw material, by evaporating a portion of the liquid fuel obtained by heating the raw material, in pulse form.    USE - For use in reforming hydrocarbon fuels, such as methanol used for fuel cells mounted in digital camera, mobile telephone, notebook personal computer, small projector, digital camcorder, small printer, and other portable electronic devices.    ADVANTAGE - The leakage of liquid raw material into the catalyst space is prevented, so raw material holding space can be rapidly filled with the raw material, without the need for a pump or pressure tank, and without the need for heating the raw material. A constant quantity of micro liquid raw materials can be discharged at high speed, even without mechanical action of a pump. The electric power generation of the fuel cell is increased.    DETAILED DESCRIPTION - A controller adjusts the flow rate of raw material with respect to the catalyst space, and controls a discharge port among several discharge ports and stages heated in pulse form. The controller adjusts the frequency of heating in the ports, and reduces frequency difference of discharge. The catalyst in the catalyst space performs steam modification reaction and partial-oxidation reaction of hydrocarbon compound. An INDEPENDENT CLAIM is included for electric power generating apparatus comprising a fuel reformer that generates hydrogen gas using liquid raw material. A re-circulating unit recovers the water generated with electric power generation, from the fuel cell, and re-circulates the recovered water.
