PROBLEM TO BE SOLVED: To provide a fuel cell system capable of measuring the correct flow rate of a raw material even those are ripples in raw material supply, and realizing a small size at a low cost. SOLUTION: This fuel cell system is equipped with a fuel cell 11 generating power with fuel gas and an oxidizing agent gas; a fuel gas producing part 14 producing reformed gas by steam-reforming raw gas; a raw gas pressure raising pump 16 raising the pressure of the raw gas; a pressure loss part 17 reducing the pressure of the raw gas; a differential pressure sensor 18 measuring the pressure loss in the pressure loss part 17; a pressure sensor 19 measuring the pressure inside a raw gas supply pipe and a temperature sensor 20 measuring the temperature inside the raw gas supply pipe; a computing means 21 computing the flow rate of the raw gas; a control part 22 controlling the capacity of the raw gas pressure raising pump 16 based on the flow rate of the raw gas; and an air blower 23 supplying air acting as the oxidizing agent gas to the fuel cell 11. |
