  "textContent": "Disclosed herein is a cooling/heating apparatus using waste heat from a fuel cell. The cooling/heating apparatus comprises a fuel cell (50), a hydrogen modifying unit (150), a cooling/heating unit (60), and refrigerant heating units. The cooling/heating unit (60) includes at least one compressor (61), a four-way valve (62), an outdoor heat exchanger (63), an expansion device (64), and an indoor heat exchanger (65), to establish a heat pump type refrigerant cycle. The refrigerant heating units provide waste heat recovered from the fuel cell (50) and the hydrogen modifying unit (150) to a suction-side refrigerant line (67 and 167) connected to the suction side of the compressor (61) included in the cooling/heating unit (60) to raise the temperature of a refrigerant. During a heating operation, the cooling/heating apparatus can achieve an enhancement in heating performance and an enhancement in system efficiency.",
