<P>PROBLEM TO BE SOLVED: To provide a fuel cell power generating device improved in overall efficiency. <P>SOLUTION: The fuel cell power generating device has a power supply block 106 that has a small capacity power supply 116 and a large capacity power supply 117. The small capacity power supply 116 has a small capacity AC/DC converter 118 and a small capacity switching means 120. The large capacity power supply 117 has a large capacity AC/DC converter 122 which converts a commercial AC 103 into a third prescribed voltage, and a large capacity switching means 123 which outputs a third prescribed voltage when the power generation block 105 is started and finished, and outputs the output voltage of a stack 107 to a large capacity power equipment in the power generation block 105 upon power generation, and does not output to the large capacity power equipment in the power generation block 105 when shut down. <P>COPYRIGHT: (C)2010,JPO&INPIT |
