PROBLEM TO BE SOLVED: To provide a control device for a fuel battery system that can enhance the determination precision of flooding.SOLUTION: A control device 200 for a fuel battery system 100 is configured to estimate a proper IV characteristic corresponding to deterioration degree of catalyst of a single cell 1 based on an operation history of the fuel battery system 100, calculate a proper temperature of single cells 1 corresponding to the load of a fuel battery stack 10 based on the proper IV characteristic, acquire the temperature of at least two single cells 1 of a representative cell selected from the single cells 1 and a flooding determination cell in which flooding is more liable to occur than the representative cell, and determines that flooding occurs in at least the flooding determination cell when the temperature of the flooding determination cell is equal to a proper temperature or more, and the temperature difference between the flooding determination cell and the representative cell is equal to a predetermined value or more.SELECTED DRAWING: Figure 1 |
