| 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.
