Based on an oxygen concentration of a treatment space (11a), which is detected by a first oxygen sensor and a second oxygen sensor and Ct, which is a target value of oxygen concentration; MV1, which is an operation quantity, is determined within a range of operation quantity from an upper limit of operation quantity to a lower limit of operation quantity by a feedback control loop. Next, deducted is MV2, which is the operation flux which is a value after conversion of MV1, which is a determined operation quantity, when the operation quantity range is converted into a limited range made by narrowing at least one from among an upper limit and a lower limit of a flux range wherein an MFC (34) controls a hydrogen flux. Additionally, outputted is MV2 which is a deducted operation quantity on the MFC (34). |
