<P>PROBLEM TO BE SOLVED: To realize a shortening of warming-up time of a hybrid power supply system having a fuel cell and a secondary power source. <P>SOLUTION: This is a power supply system for supplying power to a load. The power supply system comprises a fuel cell system having a fuel cell capable of connecting to the load, a secondary power source system having a plurality of two-way DC-DC converters that are provided in parallel between a rechargeable secondary battery and the load, a heat transmission part capable of transmitting heat from the plural two-way DC-DC converters to the fuel cell through a prescribed medium, and a control part capable of controlling the fuel cell system and the secondary power source system. This control part has a warming-up mode which is a control mode that makes a power supply direction of at least one DC-DC converter out of the plural two-way DC-DC converters inverse to the power supply direction of the other two-way DC-DC converters. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
