A cooling system and method for an auxiliary braking device of a hydrogen fuel cell truck, are provided in consideration that auxiliary braking force generated by the regenerative braking of the motor may be unnecessary and the brake resistor may be unnecessary when a sufficient amount of auxiliary braking force is generated alone by the operation of a retarder. A portion of thermal energy generated by the retarder is distributed to a stack cooling system so that the portion of thermal energy is removed by the stack cooling system. Accordingly, due to sufficient cooling of the retarder, a sufficient amount of auxiliary braking force is provided, and the brake resistor that has consumed surplus electrical energy generated by regenerative braking is removed.
