徴とする燃料電池発電装置の流量制御装置。A fuel cell that generates electricity through an electrochemical reaction between hydrogen on the hydrogen electrode side and oxygen on the oxygen electrode side, a conductor that takes out the DC power generated in this fuel cell, and the power or current installed in this conductor is detected. a first supply channel for supplying a fuel gas containing hydrogen as a main component to the hydrogen electrode side; a first control valve provided in the first supply channel; In a fuel cell power generation device comprising a second supply channel for supplying oxidant gas to the oxygen electrode side and a second control valve provided in the second supply channel, The hydrogen utilization rate or oxygen utilization rate is calculated from the output signal and the fuel gas flow rate and hydrogen concentration or the oxidant gas flow rate and oxygen concentration, and this calculated value is combined with the preset or commanded hydrogen utilization rate or oxygen concentration. Adjustment that controls the hydrogen utilization rate or oxygen utilization rate by manipulating the opening degree of the first control valve or the second control valve to change the fuel gas flow rate or the oxidizing gas flow rate according to the deviation from the utilization rate. 1. A flow control device for a fuel cell power generation device, characterized in that it is equipped with a flow rate control device.
