1. An air conditioner for a fuel cell electric vehicle that uses waste heat of a fuel cell stack for heating, the air conditioner comprising:
a heater core configured to circulate a heat medium from the fuel cell stack and perform the 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, wherein
when the calculated travel resistance is equal to or greater than a predetermined value, the control unit restricts an operation for the heating using the waste heat of the fuel cell stack.
