The invention discloses a fuel cell vehicle, a controller and a thermal management method and device of the fuel cell vehicle. The method comprises the steps that the electric pile voltage, the electric pile inlet temperature, the electric pile outlet temperature and the whole vehicle demand power of a fuel cell system are obtained; determining target output power of the fuel cell system according to the voltage of the electric pile, the temperature of the inlet of the electric pile and the required power of the whole vehicle, and determining first required heat dissipation capacity of electric pile cooling liquid according to the target output power; according to the pile inlet temperature and the pile outlet temperature, determining a second required heat dissipation amount of the pile cooling liquid; determining the larger value in the first required heat dissipating capacity and the second required heat dissipating capacity as the target required heat dissipating capacity of the electric pile cooling liqu
