<P>PROBLEM TO BE SOLVED: To provide a fuel cell system without performance degradation due to water generated at a fuel cell power generating part nor discomfort at use, capable of simply and surely collecting the water. <P>SOLUTION: The fuel cell system is provided with a fuel cell power generating part 50 having a fuel electrode 55, a solid electrolyte 54 and an air electrode 53, and a heat-exchanging chamber 110 generating water by cooling gas discharged from the fuel cell power generating part 50. Power is generated by power generation reaction utilizing fuel at the fuel cell power generating part 50. Electricity generated by the power generation is utilized as a driving source for an electric equipment or the like, and water is generated in accordance with the power generation reaction. The water is transpired in the gas and the gas is heat-exchanged in the heat-exchanging chamber 110, and the water transpired in the gas is coagulated to become droplets. The droplets produced in the heat-exchanging chamber 110 stays inside the heat-exchanging chamber not leaking outside, so that the fuel cell system is free from performance degradation due to water and from an uncomfortable feeling at use, and it can simply and surely collect the water. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
