The invention belongs to the technical field of automobile thermal management, and provides an extended-range fuel cell thermal management system, a control method thereof and an automobile. Comprising a heating circulation loop, a refrigeration circulation loop, an electric pile circulation loop and a first heat exchanger. The electric pile circulation loop sequentially passes through an electric pile and the first heat exchanger, the refrigeration circulation loop sequentially passes through a refrigeration unit and the first heat exchanger, and the heating circulation loop sequentially passes through a heater and the first heat exchanger. And the heat circulation loop, the refrigeration circulation loop and the electric pile circulation loop exchange heat in the first heat exchanger. When the electric pile is in cold start, the heating circulation loop heats the electric pile through the first heat exchanger and the electric pile circulation loop, so that the probability of successful cold start of the fuel cell is improved. When the electric pile operates normally, the electric pile circulation loop exchanges heat with the heating circulation loop through the first heat exchanger, and the heat utilization rate of the fuel cell is improved by utilizing the heat of the electric pile through the heating circulation loop.
