Abstract:
1. A fuel cell control system comprising: a fuel cell stack; a fuel cell system for taking out an electric power generated by the fuel cell stack to be supplied to a load; and a control section for controlling an electric power generating operation of the fuel cell stack based on a sensor signal inputted from a sensor disposed in the fuel cell system, wherein the control section controls the fuel cell system such that, during startup of the fuel cell system, a gas supply pressure of the fuel cell stack in compliance with the sensor signal inputted from the sensor is discriminated to be stabilized at an electric power generation start pressure of the fuel cell stack, a time duration, involving an electric power taking out start timing at which the electric power is taken out from the fuel cell stack, is set as a period in which the sensor signal is held at a preceding value and gas supply to the fuel cell stack is commenced based on the sensor signal held at the preceding value.
