<P>PROBLEM TO BE SOLVED: To improve power generation efficiency by removing smoothly gas generated on the fuel electrode side of a fuel cell and by making smooth the supply of liquid fuel to a fuel electrode and reaction at the fuel electrode accompanied by the supply of liquid fuel in the fuel cell system utilizing a fuel cell using liquid fuel. <P>SOLUTION: The fuel cell system A comprises a fuel cell 1 which has a cell body interposing an electrolyte membrane 11 by a fuel electrode 12 and an air electrode 13 and an anode chamber (fuel supply chamber) 14 which is installed adjacent to the fuel electrode 12 of the cell body and has a liquid fuel supply port 141 and a liquid fuel recovery port 142, and a liquid supply part F for supplying the liquid fuel from the liquid fuel supply port 141 to a chamber 14. In order to remove gas generated on the fuel electrode side of the cell body, at least one of pressure fluctuations in the anode chamber 14 and the reciprocal flow of the liquid in the anode chamber 14 is generated, and the liquid fuel is supplied from the liquid fuel supply part F to the anode chamber 14. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
