The invention discloses a fuel cell waste heat utilization system and a vehicle, the fuel cell waste heat utilization system comprises a heat pump circulation assembly and a power generation assembly, and the heat pump circulation assembly comprises a first heat exchanger, a first working medium pump and a first control valve; the first heat exchanger is used for absorbing heat from galvanic pile cooling water through a heat pump working medium; the first working medium pump is used for pressurizing the heat pump working medium in the first heat exchanger to increase the pressure and temperature; the power generation assembly comprises an expansion machine unit and a power generator. The expansion machine unit is used for doing work through internal energy of a heat pump working medium. The power generator is connected with the expansion machine unit and used for generating power to output electric energy under driving of the expansion machine unit. The first working medium pump is arranged between the first heat exchanger and the first control valve, the pressure and the temperature of a heat pump working medium heated in the first heat exchanger are further increased after the heat pump working medium is pressurized by the first working medium pump, the heat energy grade of heat supplied to the expansion machine unit is improved, the generator outputs more electric energy, and the waste heat utilization rate is increased.
