    • An alkaline fuel cell having an electrolyte, and anode and cathode electrodes disposed on two sides of the electrolyte is provided. A fuel cell system has this fuel cell, a discharge passageway that is connected to a discharge opening of the fuel cell and that discharges from the fuel cell an exhaust fuel containing unreacted fuel, and a circulation passageway that is connected to an introduction opening for introducing the fuel into the fuel cell and that circulates and supplies the exhaust fuel to the fuel cell. The fuel cell system further includes fuel/water separation means linked to the discharge passageway and the circulation passageway and disposed between the discharge and circulation passageways. The means separates and removes water from the exhaust fuel flowing in from the discharge passageway, and then causes a concentrated fuel from which water has been separated and removed to flow into the circulation passageway.

    • The voltage application unit first applies voltages (+,+,0,−,−,0) respectively to the electrostatic delivery electrodes 37 belonging to the phase ‘a’, the phase ‘b’, the phase ‘c’, the phase ‘d’, the phase ‘e’, and the phase ‘f’, and then successively applies voltages (0,+,+,0,−,−), voltages (−,0,+,+,0,−), voltages (−,−,0,+,+,0), voltages (0,−,−,0,+,+), and voltages (+,0,−,−,0,+). The voltage application unit repeats this cycle multiple times to apply the voltages to the phase ‘a’ through the phase ‘f’. The water droplets flocculated in the oxidizing gas conduits 36 are charged by electrostatic induction and travel in the direction from the inlet to the outlet of the oxidizing gas conduits 36 while being repelled or attracted by the electrostatic delivery electrodes 37 in the vicinity of the water droplets in the course of the positive-negative variation of the voltage in the cycle.

    • There are provided fine particle-carrying carbon particles, which can be used as a substitute for the existing platinum-carrying carbon particles or platinum metal particles commonly used in electrocatalysts for fuel cells or the like, and which are significantly reduced in the amount of platinum to be used in comparison with the existing platinum-carrying carbon particles, and an electrode for a fuel cell using the same carbon particles.The fine particle-carrying carbon particle comprises a carbon particle with an average particle diameter of from 20 to 70 nm, and fine particles of a metal oxide with an average crystallite size of from 1 to 20 nm, carried on the carbon particle, wherein the metal oxide contains a noble metal element such as a platinum element, and is represented by the formula: MOx in which the metal element M is partially substituted by the noble metal element. To manufacture such fine particle-carrying carbon particles, a solution containing complex ions of a metal which constitutes the fine metal oxide particle is firstly prepared; then, carbon particles are dispersed in the resulting solution to adsorb the complex ions of the metal onto the carbon particles; and the resulting dispersion is subjected to a hydrothermal treatment.
