Description
Technical field
The present invention relates to fuel cell, relate in particular to a kind of flow guide plate of fuel cell that is conducive to reduce cooling fluid flow resistance.
Background technology
Proton Exchange Membrane Fuel Cells technology is the topmost key technology of 21 century human use Hydrogen Energy.A lot of countries have all given the attention of height and support energetically to Proton Exchange Membrane Fuel Cells technology industrialization, and have obtained many substantial progress.Can predict, comprehensive industrialization of this technology will produce significant impact to future world energy supply and general layout.In modern society's life and economic construction, the importance of supply of electric power and guarantee is more and more important, improves constantly improving electrical production and service efficiency and the eco-friendly degree that requires simultaneously.Distributed power generation approach user, reduce electric power and carry at a distance, the advantage of adjusting flexibly according to need for electricity is more and more subject to the attention of various countries.
According to the operating temperature of proton exchange membrane, Proton Exchange Membrane Fuel Cells (PEMFC) can be divided into two types of low temperature and high temperature.The operating temperature of low temperature Proton Exchange Membrane Fuel Cells (LT-PEMFC) is not generally higher than 90 DEG C, have advantages of that startup is fast, power density is high, lightweight, volume is little, it requires very high to the hydrogen purity as fuel, be applicable to being connected with the regenerative resource such as solar energy, utilizing the high-purity hydrogen that brine electrolysis is produced is stable electric energy by unsettled renewable energy conversion, the operating temperature of high temperature proton exchange film fuel cell (HT-PEMFC) is at 120 DEG C to 180 DEG C, although compare the toggle speed slightly slow (needing preheating) of low temperature Proton Exchange Membrane Fuel Cells (90 DEG C of working temperature <), power density is slightly low, but high temperature proton exchange film fuel cell (working temperature 120-180 DEG C) has very strong anti-CO poisoning capability, be applicable to by natural gas very much, piped gas, methyl alcohol, propane, or even the various ways such as rubbish landfill gas and biological energy source hydrogen making of reforming, greatly reduce the use threshold of fuel cell technology for power generation, and due to high-temperature fuel cell operation and more than 120 DEG C high temperature, pile generates water and all vaporizes, can not cause fuel cell pack inner flow passage water blockoff, the reliability of fuel cell improves greatly, service life exceeds more than 10 times than low-temperature fuel cell.In addition, the high temperature that high temperature proton exchange film fuel cell (working temperature 120-180 DEG C) operation produces is more easily recovered utilization, is integrated into cogeneration system (CHP) and further improves its capacity usage ratio.High temperature proton exchange film fuel cell has the advantages such as operation stability is high, system is simple, the life-span is long, and its application is very wide, from small-sized resident's home terminal cogeneration, to building, the distributed power generation of community, large-scale power station, center.
High temperature proton exchange film fuel cell (working temperature 120-180 DEG C) technology is as using solid-state proton exchange membrane as electrolytical one in fuel cell, the basic structure of its electrolytical key property, membrane electrode (membraneelectrode assembly MEA) and the working method of fuel cell are similar with low temperature Proton Exchange Membrane Fuel Cells (90 DEG C of working temperature <): electrolyte is same is the conductor of proton, the insulator of electronics, and has low-down gas permeability; Membrane electrode MEA is its core component equally, and the bipolar plates of membrane electrode and its both sides has formed the elementary cell-fuel-cell single-cell of fuel cell; The basic structure of membrane electrode is also middle proton exchange membrane, and film both sides are respectively negative electrode and anode electrocatalyst, the outer attached gas diffusion layers of anode and cathode eelctro-catalyst; The course of work, hydrogen sees through porose gas diffusion layers to catalyst layer, hydrogen one side of fuel cell is anode, it is proton and electronics that catalyst makes Hydrogen Separation, proton reaches negative electrode (being oxygen one side) by electrolyte, electronics flows through an external circuit and arrives negative electrode, generates water at negative electrode proton, electronics and oxygen reaction.
The proton conduction mechanism of the high temperature proton exchange film that high temperature proton exchange film fuel cell (working temperature 120-180 DEG C) uses is completely different from the proton exchange membrane proton conduction mechanism that low temperature Proton Exchange Membrane Fuel Cells (90 DEG C of working temperature <) uses.In low temperature Proton Exchange Membrane Fuel Cells running, proton must carry hydrone (at most time a proton need carry 14 hydrones) when the film, under the help of hydrone, could pass film, parch or the inadequate situation of humidity under proton can not or can pass on a small quantity film, thereby increase the resistance of film, cause reducing rapidly performance, reduce the life-span.The conduction mechanism of high temperature proton exchange film is: polybenzimidazoles (PBI) phosphate impregnation forms lattice, be equivalent to form dihydric phosphate, being equivalent to relay 150 DEG C of-200 DEG C of temperature range inner proton by the hydrogen bond grid of dihydric phosphate equally transmits, complete the process of proton through film, in this process, do not need to carry hydrone, but along with the reduction of temperature, the conductivity of film also will reduce.Therefore the service conditions of high temperature proton exchange film fuel cell is different from low temperature Proton Exchange Membrane Fuel Cells completely.
A typical battery stack generally includes: water conservancy diversion import and the flow-guiding channel of (1) fuel and oxidant gas, be distributed to fuel (hydrogen-rich gas obtaining after reforming as hydrogen, methyl alcohol or by methyl alcohol, natural gas, gasoline) and oxidant (being mainly oxygen or air) in the guiding gutter of each anode, cathode plane equably; (2) import and export and the flow-guiding channel of cooling fluid (as water), cooling fluid is evenly distributed in each battery pack inner cooling channel, dispels the heat by the heat absorption that in fuel cell, hydrogen, the exothermic reaction of oxygen electrochemistry generate and after taking battery pack out of; (3) outlet of fuel and oxidant gas and corresponding flow-guiding channel, fuel gas and oxidant gas are in the time discharging, and portability goes out the liquid generating in fuel cell, the water of steam state.Conventionally, the import and export of all fuel, oxidant, cooling fluid are all opened on an end plate of fuel cell unit or on two end plates.
Low-temperature fuel cell, generally adopts water as cooling heat dissipation fluid at present, but it easily meets with cold start-up problem, and as at-20 DEG C, water has been formed ice, cannot start.High-temperature fuel cell, operating temperature is 120-180 DEG C, water vapor, also cannot use.Therefore, need one can resist cold anti-low temperature to freeze, also can cooling heat dissipation fluid high temperature resistant, that can not vaporize, general employing containing fluorocarbon oil at present, or other artificial oil is as cooling heat dissipation fluid, once but these fluids are penetrated on battery lead plate, just horse back contaminated electrode, scraps whole fuel cell.The easy seepage of existing guide plate cooling fluid, contaminated electrode, and also cooling fluid flow resistance is large, easily stops up.
