<P>PROBLEM TO BE SOLVED: To provide a fuel cell power supply device capable of constructing its unit case compactly and protecting a control device against heat conduction and water leakage. <P>SOLUTION: The unit case of this fuel cell power supply device has a frame 1, where a fuel reforming device 2 is installed on a crosswise bar 1a at the upper stage of the frame 1 while a control device 5 and a fuel cell body 6 are installed on a crosswise bar 1b at the middle stage in the back-to-back arrangement. A heat insulation 5a is provided on the back surface of the control device 5 while an heat insulator 5b is provided at the periphery so as to protect the control device 5 from the ambient high temperature. Auxiliary units such as a fuel pump 8 to send the crude fuel into the fuel reforming device 2, an air pump 9 to send the reaction air to the fuel cell body 6, etc., are installed on a bottom plate at the lower stage. This constitution does not require provision of any partitioning wall or heat insulating bulkhead to partition inside the unit case into two compartments, which liberates any water pipe(s) to be installed for cooling the control device 5. <P>COPYRIGHT: (C)2004,JPO |
