燃料電池システムの制御装置
Document Type and Number:
Japanese Patent JP6455408
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a controller for a fuel cell system that can reduce a cumulative driving quantity of a shunt control valve.SOLUTION: When an affirmative determination affirming that stack heating value is equal to or less than a heating value threshold is made, a heat radiation quantity of a refrigerant at a vehicular radiator 24 is suppressed as compared with that before the affirmative determination is made. Accordingly, a shut control valve 30 is inhibited from operating. Therefore, a cumulative driving quantity obtained by cumulating a variation quantity of opening of the shunt control valve 30 can be reduced. Further, a cooling water temperature, i.e. a refrigerant temperature in the vehicular radiator 24 hardly drops by the suppression of the heat radiation quantity, so that cooling water, i.e. a low-temperature refrigerant is prevented from flowing in a fuel cell stack 12. In other words, overcooling of the fuel cell stack 12 assumed to be caused as the shunt control valve 30 is inhibited from operating can be prevented.SELECTED DRAWING: Figure 1
