<P>PROBLEM TO BE SOLVED: To provide a fuel cell system with a stable operation realized through restraint of freezing of water in an ejector. <P>SOLUTION: The fuel cell system made up by providing a gas supply channel with an ejector 1 supplying new gas to be supplied to a fuel cell by joining off-gas exhausted from the fuel cell has a face with smaller abrasion resistance than an ejector base material on an inner wall face of the gas flow channel of the ejector 1. The face with the smaller abrasion resistance is formed by covering the surface of the ejector base material with a film 11 made of fluororesin such as polytetrafluoroethylene (PTFE). <P>COPYRIGHT: (C)2007,JPO&INPIT |
