<P>PROBLEM TO BE SOLVED: To provide a fuel cell power generating device equipped with a stack and a power generating system substantially restraining performance degradation of the stack during the period from a state of storage before its loading on the power generation system to its connection with the system. <P>SOLUTION: The device is provided with stack connecting parts 41 to 44 airtightly sealing the stack so as not to have oxygen mixed in before its loading on the power generating system and releasing it the instant it is connected with the power generating system, and a system connecting part releasing the sealing of the stack at the same time as its connection with the system. Even if a storage period from the storage state to the loading is prolonged, the stack is airtightly sealed, connected to the power generating system to have both communicated with each other so that even a faint volume of oxygen mixed into the stack is prevented from infiltrating. Therefore, performance degradation of the stack due to oxidation of a remnant solvent or the like remaining on electrode catalyst can well be restrained to obtain a fuel cell power generating device with high reliability. <P>COPYRIGHT: (C)2007,JPO&INPIT |
