Functional test and demonstration apparatus for fuel cell power system

A functional test and demonstration apparatus is provided for a fuel cell power system, which includes a mainframe for supporting a fuel cell stack. A hydrogen supply module supplies hydrogen to the fuel cell stack, and excessive hydrogen flows out from a hydrogen gas outlet of the fuel cell stack. Air is drawn in and supplied to the fuel cell stack by a blowing device, and flows out from an air outlet of the fuel cell stack. A liquid cooling device is connected between a coolant inlet and a coolant outlet of the fuel cell stack to remove heat from the fuel cell stack. A humidifier is used to properly humidify the air before it is conveyed to the fuel cell stack. The signals detected from various components of the fuel cell power system are sent to a control device which controls the operation of the components.
