<P>PROBLEM TO BE SOLVED: To provide a fuel cell realizing high efficiency operation and long life by reducing operational loss such as exchanging defective articles or the like generated after power generation by realizing inspection of a polymer film in an isolated form before starting power generation and removing the defective articles having a cross-leak amount of larger than a prescribed value. <P>SOLUTION: The solid electrolyte fuel cell comprises a polymer electrolyte film not including pinholes with an area larger than a film expansion area calculated by multiplying a variation of moisture content of the film before and after starting operation, by a result of multiplication of the film area and an increasing rate of the film area expressing by a percentage of the increasing rate of the film area per a unit percentage increment of the moisture content of the film. Further, the inspection of pin-holes is to be carried out before starting the power generation. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
