Under-train fuel cell power integrated system for motor train unit

Abstract

The embodiment of the invention discloses an under-train fuel cell power integrated system for a motor train unit. The under-train fuel cell power integrated system comprises a fuel cell stack system,a hydrothermal management system, an air supply system, a hydrogen supply system, a fire extinguishing system, an electric control system, a hydrogen recovery system, a humidifier, a lithium batteryand an air pump which are mounted on a mounting frame, wherein the hydrothermal management system can provide a cooling medium for the system and manage internal heat after the system operates, the air supply system can provide the air required by chemical reaction for a galvanic pile, the hydrogen supply system can provide hydrogen required by chemical reaction of the galvanic pile, the fire extinguishing system can discover the fire situation of the integrated system in time and perform fire extinguishing treatment, and safety guarantee is provided for safety of the motor train unit and personnel on the train. The system has advantages of easiness in vehicle maintenance, no power grid operation, strong low-temperature environment starting capability, strong environmental adaptability, zero emission in the vehicle operation process, environmental friendliness, high safety and the like.

Description

technical field [0001] The invention relates to the technical field of EMUs, in particular to an under-car fuel cell power integration system for EMUs. Background technique [0002] At present, EMUs in various countries in the world are divided into electric EMUs and internal combustion EMUs. Although the electric multiple units have the characteristics of high power, light axle load, and "zero" emission during operation, there are high construction costs of the ground power supply system in the early stage, low safety of high-voltage equipment, long construction period, poor environmental adaptability, and Pantograph friction loss and other shortcomings; while the defects of the internal combustion EMU are due to the low integration of the internal combustion power transmission system, the poor flexibility of vehicle marshalling, and the large space occupied by the vehicle, which reduces passenger comfort and passenger capacity. The starting ability is poor, and the use of...

Problems solved by technology

Although the electric multiple units have the characteristics of high power, light axle load, and "zero" emission during operation, there are high construction costs of the ground power supply system in the early stage, low safety of high-voltage equipment, long construction period, poor environmental adaptability, and Pantograph friction loss and other shortcomings; while the defects of the internal combustion EMU are due to the low integration of the internal combustion power transmission system, the poor flexibility of vehicle marshalling, and the large space occupied by the vehicle, which reduces passenger comfort and passenger capacity. The starting ability is poor, and the use of petroleum resources as fuel will bring about environmental problems that people pay attention to, such as air pollution, global warming, and the reduction of earth's petroleum resource reserves.

Therefore, it can be seen that the power systems used by the existing electric multiple units and internal combustion multiple units cannot meet the needs of the future development of the multiple units.
