The invention discloses a fuel cell thermal management system, a control method and device thereof and a vehicle. The method comprises the steps that the vehicle state is determined, and the vehicle state comprises the flameout state and the starting state; supplying power to the fuel cell thermal management system according to the vehicle state; the ion concentration is obtained in real time, and the ion concentration is the ion concentration of the cooling liquid in the vehicle; comparing the ion concentration with a preset concentration threshold value to obtain a comparison result; a first loop and a second loop are controlled according to the vehicle state and the comparison result, so that the ion concentration is smaller than a preset concentration threshold value, the first loop is used for reducing the ion concentration, and the second loop is used for isolating the cooling liquid from a fuel cell stack of the vehicle. The invention solves the technical problem that the service life of the fuel cell stack is influenced because the fuel cell stack is damaged when high-concentration ions enter the fuel cell stack.
