Abstract
A fuel cell power source is provided with a means for feeding a liquid fuel cell and water through time-sharing with the use of a single pump so as to maintain concentration of the liquid fuel, thereby it is possible to decrease the number of accessories in order to reduce the size of the fuel cell power source and as well to reduce the costs.
Claims23
A fuel cell power source comprising a fuel cell part including an anode, a cathode arranged so as to be opposed to the anode, a solid polymer electrolyte membrane interposed between the anode and the cathode, for power generation, and a liquid fuel supply part for feeding a liquid fuel and water into the fuel cell part, wherein the liquid fuel supply part includes a means for feeding the fuel and the water to the anode by a single pump through time-sharing.
A method of operating a fuel cell power source composed of a fuel cell power source comprising a fuel cell part including an anode, a cathode arranged so as to be opposed to the anode, a solid polymer electrolyte membrane interposed between the anode and the cathode, for power generation, and a liquid fuel supply part for feeding a liquid fuel and water into the fuel cell part, wherein the liquid fuel and the water which are fed to the liquid fuel supply part is fed through time-sharing by a single pump.
