Abstract:
1. A hybrid power supply system comprising: a fuel cell configured to react hydrogen gas supplied from a hydrogen supply device with oxygen gas supplied from an oxygen supply device to generate electric power; an operating device electrically connected to the fuel cell, the operating device operated using the electric power generated by the fuel cell; a cooling device delivering coolant to the fuel cell to cool the fuel cell; a temperature monitor sensing a temperature of the fuel cell or a temperature of the coolant; a controller configured to control the electric power generated by the fuel cell in such a manner that the generated electric power is larger than electric power consumed by the operating device during a warm-up mode in which the temperature sensed by the temperature monitor is not higher than a predetermined threshold temperature; and a secondary power storage device electrically connected to the fuel cell and the operating device, whereby a supply of electric power generated by the fuel cell and not consumed by the operating device is used to charge the secondary power storage device.
