    摘要： During a time zone where a power demand is smaller than an average value of the entire power demands of homes, an excess portion obtained by subtracting a power demand from a base power portion supplied by PEFC (1) is charged in a capacitor (7) and a lead storage battery (8) in advance; and during a time zone where a power demand is larger than the average value, a peak power portion exceeding this average value is discharged from the capacitor (7) and the lead storage battery (8); thereby enabling the system to sufficiently meet daily home-use demand with requisite minimum equipment while effectively using surplus power. Thus, energy efficiency can be enhanced without wasting energy, and also cost efficiency can be improved.

    摘要： A fuel cell comprises an anode oxidizing a fuel, a cathode reducing an oxidizing agent, a polymer electrolyte disposed between the anode and the cathode, whereby an assembly is constituted by the anode, cathode and polymer electrolyte, a pair of gas diffusion layers disposed at both sides of the assembly of the anode, and the cathode, a bipolar plate for providing the fuel to the gas diffusion layer, and another bipolar plate for providing the oxidizing agent to the gas diffusion layer, wherein at least one of the gas diffusion layers includes a porous gas diffusion layer substrate having a hydrophilic surface layer, and wherein particles of a water-repellent material are dispersed in pores of the porous gas diffusion layer substrate. This results in a higher cell voltage and a higher power at a high current density, prevention of a flooding and a longer cell lifetime.

    摘要： A fuel battery system of the present invention includes: an alkaline fuel battery; a fuel supply device for supplying a fuel to an anode of the fuel battery; an oxidizing agent supply device for supplying an oxidizing agent to a cathode of the fuel battery; a liquid supply device which supplies a liquid to the cathode; a valve which switches between fluids to be supplied to the cathode; and a control device which controls the switching of the valve. The fuel battery system suppresses the neutralization of an anion-exchange electrolyte due to carbon dioxide in the air, by supplying the liquid from the liquid supply device to the cathode and making the cathode in the state of being immersed in the liquid when the fuel battery stops power generation.
