PROBLEM TO BE SOLVED: To provide a fuel battery system that can recover a sufficient amount of condensed water at a condensation portion irrespective of the temperature of heat medium stocked in a heat storage device.SOLUTION: When a third temperature increases to a third heat radiation start temperature or more during stop of a heat radiator 3, an operation controller C equipped to a fuel battery system operates the heat radiator 3 to cool a heat medium. When the third temperature decreases to less than a third heat radiation stop temperature during operation of the heat radiator 3, the operation controller C stops the operation of the heat radiator 3, and controls the operation of a heat medium pump 4 so that a first temperature is equal to a target heat medium temperature. In a case where the target heat medium temperature is set to a first target heat medium temperature during operation of the heat radiator 3, the operation controller C changes the target heat medium temperature to a second target heat medium temperature when the second temperature increases to a second reduction switching temperature or more. In a case where the target heat medium temperature is set to a second target heat medium temperature during operation of the heat radiator 3, the operation controller C changes the target heat medium temperature to a first target heat temperature when the second temperature decreases to less than a second increase switching temperature.SELECTED DRAWING: Figure 1 |
