Problems solved by technology

[0004] Currently commonly used internal combustion engine drive systems, about 10% of the heat is lost in friction, 25% of the heat is taken away by the exhaust gas, and 40% of the heat is transferred to the cooling water outside the cylinder, so the efficiency of the system is only 20-30%. Through technological innovation, it can only reach about 40%, and the utilization rate of energy is low
In addition, city buses with internal combustion engines emit harmful substances such as particulates, sulfur oxides, and nitrogen oxides during operation, and at the same time emit greenhouse gases—carbon dioxide, which pollutes the urban environment.
[0005] At present, there is no public report on related technologies of proton exchange membrane fuel cell-internal combustion engine combined driving air conditioning system

Abstract

The invention consists of a fuel pole compressor, a fuel pole heat-exchanger, a proton exchanging film fuel cell, an internal combustion engine, a gas air conditioner, a driver, a motor, an air pole heat-exchanger and an air pole compressor. The system fuel is hydrogen and using the electrochemical reaction of hydrogen and air in the fuel cell produces electric energy to drive buses, and the imperfect reaction hydrogen enters into the internal combustion engine for combustion to produce mechanical energy for providing buses with partial power, and meanwhile the produced gas for providing buses with hot / cold air through gas air conditioners.

Description

technical field [0001] The invention relates to a proton exchange membrane fuel cell-internal combustion engine combined drive air conditioning system, which is suitable for urban public transport passenger buses and belongs to the technical field of energy utilization. Background technique [0002] With the increase in the number of automobiles, it has brought problems such as a surge in oil demand and environmental degradation, and people are facing dual pressures on oil resources and environmental protection. [0003] In order to protect the environment and improve energy efficiency, countries around the world urgently need to develop new vehicle drive systems. Fuel cell power generation drive technology converts the chemical energy of fuel directly into electrical energy without being limited by the Carnot cycle. Among them, the proton exchange membrane fuel cell (Proton Exchange Membrane Fuel Cell; PEMFC) has the advantages of environmental friendliness, long life, low...
