The invention provides a thermal management system of a fuel cell vehicle and a control method, and relates to the field of fuel cells. The thermal management system of the fuel cell vehicle comprisesa cell stack, a water-liquid pipeline, a heating structure and a controller. The water-liquid pipeline communicates with the cell stack and comprises a main pipeline, a first branch and a second branch, the main pipeline and the first branch sequentially communicate to form a closed loop, and the second branch is connected with the first branch in parallel. A temperature measuring element is arranged at a water outlet, close to the cell stack, of the water-liquid pipeline, and the heating structure is further arranged on the main pipeline. The first branch is connected with the heating structure, valves are further arranged on the water-liquid pipeline, and the controller is electrically connected with the temperature measuring element, the heating structure and the valves separately. Thecontroller controls cooling liquid to circulate in the specific loop according to a received outlet water temperature signal sent by the temperature measuring element and the on-off state of a warm air switch in a cab. By directly using heat of the heated cooling liquid for heating in the vehicle, the energy utilization rate is high, and it is guaranteed that the vehicle has more sufficient power.
