The invention provides a tail emission control method and device of a fuel cell power automobile and the automobile, and relates to the field of new energy vehicles, the tail emission control device comprises a tail emission pipeline and a catalytic generator, and an inlet of the tail emission pipeline is used for receiving tail gas exhausted by an electric pile of a fuel cell; the catalytic generator is arranged in the tail gas exhaust pipeline, and the catalytic generator is used for catalyzing tail gas exhausted by the electric pile so as to release heat; the tail emission control method comprises the steps that a transition temperature value and an external environment temperature value are read, and a target hydrogen discharging mode is determined based on the transition temperature value, the external environment temperature value and the mapping relation among the transition temperature value, the external environment temperature value and the hydrogen discharging mode; and switching the hydrogen discharge mode of the fuel cell according to the target hydrogen discharge mode. Based on the transition temperature and the external environment temperature value, the hydrogen discharging mode is switched, the temperature of the tail gas is increased through the catalytic generator, and it is guaranteed that water in the tail gas is discharged out of the tail gas discharging pipeline in a gaseous state.
