The present disclosure relates to the technical field of fuel cells, in particular to a system for heat recovery of a fuel cell and a vehicle. The system comprises a cold source side, a heat source side and a thermoelectric conversion module located between the cold source side and the heat source side. The fuel cell exchanges heat with the heat source side; when the temperature of the fuel cell is greater than a preset value, the thermoelectric conversion module converts heat energy into electric energy; when the temperature of the fuel cell is less than the preset value, the thermoelectric conversion module is reversely electrified to heat the heat source side. According to the present disclosure, the thermoelectric conversion module is used, and low-grade heat energy is directly converted into electric energy by using the Seebeck effect of semiconductor thermoelectric power generation material, so that heat dissipation burden of a heat dissipation system can be relieved, the electric energy can also be reused by other vehicle-mounted electric appliances, the operation efficiency of the system is improved, and the purpose of saving energy is achieved; moreover, an electric pile can be heated in a reverse direction under the electrifying condition, the cold start performance of the system is improved, the fuel cell does not need to be heated by means of a PTC, and the system cost is effectively reduced.
