Description
Technical field
The present invention relates to Proton Exchange Membrane Fuel Cells (PEMFC) heap thermal cycle simulation, belong to vehicle fuel battery dynamical system thermal management technology field.
Background technology
Fuel-cell vehicle is to have substituted traditional combustion engine powered system by fuel cell power system with respect to the main distinction of orthodox car.The 2.5-3 that PEMFC dynamical system waste heat is about the traditional combustion engine dynamical system doubly, reactor behavior is to responsive to temperature, and coolant temperature and circumstance of temperature difference are little, have bigger heat management difficulty.Heat management not only influences highly significant to the PEMFC power system performance, what is more important, and can will directly influence it operate as normal.Therefore, the heat management of PEMFC dynamical system becomes the key issue in the fuel cell car research and development.
Fuel cell pack is the main thermal source of dynamical system, fuel chemical energy respectively accounts for 50% approximately by electric energy and the heat energy that fuel cell pack transforms, as a fuel cell pack that is output as 75KW, the heat of taking out of by heat management is about 75KW, is 2.5～3 times of traditional combustion engine.For drying and the overheating operation that prevents film, need corresponding heat transfer mechanism and remove the huge heat that electrochemical reaction produces.In addition, because the temperature difference is less between fuel cell and running environment, the heat extraction of reactor becomes one and has challenging problem.The heat balance of PEMFC inside plays key effect to fuel cell performance, life-span and security of operation.Therefore, study the heat extraction performance and the thermal uniformity of fuel cell, control inside battery fluid flows and conducts heat, and guarantees the heat balance and the water balance of reactor.
The experimental study of fuel cell power system heat management comprises the research of fuel cell pack heat management, the research of system integration heat management, the content of aspects such as the special equipment of heat management (as heat exchanger, cooling fan etc.) research and waste heat utilization technology research.
Use true fuel cell pack to carry out the experimental study of dynamical system heat management, there are problems such as the hydrogen potential safety hazard is big, the hydrogen consumption is big, and auxiliary system complexity such as supply of fuel, it is bigger and costly to cause testing difficulty, is not suitable for effectively carrying out flexibly of the special experimental study of heat management.
Summary of the invention
The thermal cycle simulation that the purpose of this invention is to provide a kind of pem fuel cell stack substitutes true fuel cell pack, uses for the experimental study of dynamical system heat management.
The structure that fuel cell pack is described is as follows: the single-cell structure of true fuel cell pack as shown in Figure 1, its core is made up of proton exchange membrane 3, anode catalyst layer 4a, cathode catalysis layer 4b, diffusion layer 5, bipolar plates 8 and heat extraction plates 9 etc.Catalytic Layer 4a, 4b are the places that electrochemical reaction takes place.The effect of diffusion layer 5 is to support Catalytic Layer 4a, 4b, collected current, and provide electron channel, gas passage and drainage channel for electrochemical reaction.Proton exchange membrane 3, Catalytic Layer 4a, 4b and diffusion layer 5 are formed electrode altogether.Bipolar plates 8 provides reaction gas passage and the effect of collected current is arranged.Hydrogen and oxygen (perhaps air) flow through the runner 6 of bipolar plates 8 respectively and diffused into electrode at 7 o'clock.In the anode-side of electrode, hydrogen atom is hydrogen ion and electronics by ionization under catalyst action, and wherein hydrogen ion passes proton exchange membrane 3 and transfers to cathode side, electronics then through the external circuit load flow to negative electrode; At cathode side, catalyst makes the oxygen atom of hydrogen ion and negative electrode and the electronics that returns from the external circuit be combined into hydrone again, and the while release heat.On heat extraction plates 9, the outer loop cooling water flows through path 10, takes away big quantitative response heat production, keeps the stable of battery operated temperature.
Pem fuel cell stack thermal cycle simulation of the present invention is superimposed together by a plurality of cell boards and forms.Each cell board is by a simulation electrode, two bipolar plates, and two heat extraction plates are formed.Post the thermal resistance sheet on simulation electrode and bipolar plates, the heat production situation of energising back analog fuel battery pile has cooling-water duct on heat extraction plates.Two bipolar plates fit with the two sides of simulation electrode respectively, and two heat extraction plates fit with two bipolar plates respectively.
Adopt thermal cycle simulation of the present invention can come the different operating situation of analog fuel battery pile, for experimental study by the caloric value of controlling every thermal resistance.
