PROBLEM TO BE SOLVED: To provide a controller for a fuel battery system which suppresses the deterioration of combustion catalysts by an abnormally high temperature. SOLUTION: The controller for the fuel battery system equipped with a reforming catalyst (3) for forming reforming gas containing hydrogen from raw fuel vapor consisting of fuel and water as raw fuel, a fuel battery stack (1) for generating electric power by using the reforming gas and air and the combustion catalyst (9) for burning the exhaust gas discharged from the fuel battery stack detects the flow rate of the reforming gas flowing into the combustion catalyst and the concentration of the components of the reforming gas and controls the quantity of the air supplied to the combustion catalyst in such a manner that the temperature of the combustion catalyst attains a permissible temperature in accordance with the result of the detection. |
