<P>PROBLEM TO BE SOLVED: To provide a method for inspecting a fuel cell stack, for acquiring accurate inspection results while greatly shortening a required time for inspection. <P>SOLUTION: Four types of current-voltage characteristic inspection, fuel gas flow amount responsiveness inspection, oxidant gas flow amount responsiveness inspection, and cross-leak inspection are continuously carried out in sequence. Since the current-voltage characteristic inspection is first carried out, voltage is accurately measured in the state of suppressing a voltage variation due to continuous power generation. A time for inspecting the following three items is shortened by eliminating minute-current power generation or inert gas purge which is conventionally carried out before inspection. <P>COPYRIGHT: (C)2011,JPO&INPIT |
