PURPOSE: A heating system of a fuel cell vehicle using waste heat of cooling water is provided to improve fuel efficiency by additionally employing a heater core that heats indoor air using the waste heat of cooling water discharged form a fuel cell stack. CONSTITUTION: A heating system of a fuel cell vehicle using waste heat of cooling water comprises an electric heater(41) and a heater core(42). The electric heater heats the air blown by a blower fan and discharged to an indoor place. The heater core is installed in a cooling water line in which cooling water is circulated for cooling a fuel cell stack(10) and heats the air blown by a blower fan and discharged to an indoor place through heat exchange with cooling water. The heater core is installed on the downstream side of the fuel cell stack in order to heat air with the waste heat of cooling water discharged from the fuel cell stack.
