Fuel cell stack thermal management system and vehicle provided with same

The invention provides a fuel cell stack thermal management system and a vehicle provided with the system, and belongs to the technical field of fuel cell stack thermal management. Comprising a fuel cell stack; a liquid hydrogen storage tank; the liquid hydrogen heat exchanger is communicated with the fuel cell stack, the fuel cell stack is provided with a cooling water inlet and a cooling water outlet, and the liquid hydrogen heat exchanger is used for carrying out heat exchange with cooling water flowing out of the fuel cell stack; cooling water passing through the liquid hydrogen heat exchanger flows to the fuel cell stack, and the liquid hydrogen heat exchanger is communicated with the liquid hydrogen storage tank. The fuel cell stack can be started at a low temperature, so that the problem that an automobile cannot be normally started in a low-temperature state is avoided, meanwhile, the heat exchange efficiency is improved, the fuel cell stack works in a proper temperature range, and the heat dissipatio
