The invention discloses a fuel cell tail exhaust heat energy recycling system which comprises an electric pile, wherein the electric pile is communicated with a three-way switch valve through a pipeline, the three-way switch valve is communicated with a first tail exhaust through a pipeline, a front side passage of the three-way switch valve is connected with an evaporator through a pipeline, the evaporator is located in a cab, the evaporator is communicated with a second tail exhaust outside the cab through a pipeline, the electric pile is communicated with a three-way proportional valve through a pipeline, a right side passage of the three-way proportional valve is connected with a radiator through a pipeline, the radiator is connected with a right side passage of a four-way proportional valve through a pipeline, a rear side passage of the four-way proportional valve is connected with a PTC heater through a pipeline, and a front side passage of the four-way proportional valve is connected with the evaporator through a pipeline. The small cycle and the cab internal heating PTC share one component, and the cab is heated by utilizing the tail exhaust heat of the fuel cell and the system heat after normal operation, so that one PTC heating component can be reduced, the cost is saved, and the endurance mileage can be increased.
