Abstract
An air conditioner for a fuel cell electric vehicle includes a heater core configured to circulate a heat medium from a fuel cell stack and perform heating by heat exchange with air, and a control unit configured to calculate a travel resistance when the fuel cell electric vehicle travels on a road based on a road state affecting the travel resistance generated when the fuel cell electric vehicle travels and an environmental state, and control the heat exchange in the heater core based on the calculated travel resistance. When the travel resistance is equal to or greater than a predetermined value, the control unit restricts an operation for the heating using waste heat of the fuel cell stack.
