The invention discloses a brake resistor cooling system of a fuel cell vehicle, an eight-way valve and a control method. The brake resistor cooling system comprises a fuel cell system internally provided with a water pump and water cooling circulation. The fuel cell radiator I is arranged on one side of the fuel cell system and is used for radiating the fuel cell system; a brake resistance system; the fuel cell radiator II is arranged on one side of the brake resistor system; and the eight-way valve is communicated with the fuel cell system, the fuel cell radiator I, the brake resistor system and the fuel cell radiator II. The brake resistor and the fuel cell loop can share the radiator to the maximum extent, and the arrangement space and cost of the radiator of the whole vehicle are saved. And a completely independent working loop of the brake resistor and the fuel cell can be realized, so that the fuel cell is kept at an idle power point when the brake resistor works, and frequent startup and shutdown are avoided.
