Description
Technical field
The present invention relates to a kind of preparation method and testing apparatus thereof of combined electrode of fuel cell.
Background technology
Fuel cell has very long history till now from invention, and the sixties, fuel cell successfully is applied to Apollo (Appollo) mooncraft.Since the sixties, hydrogen oxygen fuel cell is widely used in the aerospace field, and simultaneously, the phosphoric acid fuel cell of MW class is also succeeded in developing.Since the eighties, various low-power batteries are applied in the every field such as aerospace, military affairs, traffic.Enter after 21 century, the technology of fuel cell is gradually improved.International energy circle prediction, fuel cell are 21 century one of the most attractive electricity-generating methods.
Fuel cell power generation is that the chemical energy with fuel directly is converted to electric energy, do not need to burn, there are not rotatable parts, energy conversion rate is 100% in theory, actual power efficient can reach 40%~60% regardless of different kinds of the device, can realize that direct Entry Firm, restaurant, hotel, family realize the cogeneration of heat and power coupling, thermal loss is not failed in transmission of electricity, comprehensive energy efficient can reach 80%, device is integrated structure, capacity can be little to only for mobile phone power, greatly to comparing with present thermal power plant, very flexible.
The present invention utilizes the advanced research project of new material single wall carbon nano-tube film aspect combined electrode of fuel cell, and it is according to being the super large surface area that utilizes single wall carbon nano-tube film to have, good chemical stability and excellent mechanical property.This research for research and development novel, low-cost, have the fuel cell of commercialization prospect significant.
MEA is the electrochemistry heart of proton membrane fuel battery (PEMFC), exactly because its variation, just so that PEMFC has presented the present flourish vital of today.Early stage combination electrode is measured up to 10mg/cm with Pt
2, the utilance of Pt is very low.Afterwards, for increasing the utilance of Pt, used the Pt/C catalyst, but the utilance of Pt is still very low, until the mid-80, the Pt carrying capacity of PEMFC combination electrode is still up to 4mg/cm
2The middle and later periods eighties, U.S. Los Alamos National Laboratory (LANL) has proposed a kind of new method, adopts Nafion proton exchange polymer solution impregnation Pt/C porous gas diffusive electrode, and hot repressing forms combination electrode on proton exchange membrane.This method has improved the utilance of precious metals pt greatly, and the platinum amount of carrying of combination electrode has been dropped to 0.4mg/cm
21992, LANL improved this method, made the Pt carrying capacity of combination electrode further be reduced to 0.13 mg/cm
2It is 0.1 mg/cm that nineteen ninety-five India's electrochemical energy research center (CEER) adopts spraying dipping legal system to get the Pt carrying capacity
2Combination electrode, functional.It is reported that in some monocells of now LANL test, the platinum carrying capacity has dropped to 0.05mg/cm on the combination electrode
2Utilize single wall carbon nano-tube film to be carrier, will further reduce the consumption of noble metal catalyst Pt.
China per capita energy resources is poor, present electrical network by mainly lack electric weight change into mainly lack system reserve capacity, peak modulation capacity, power grid construction lags behind and the traditional with serious pollution situation of generation mode under, the generating of research and development micro fuel cell is significant, and this generation mode combines and will bring huge economic benefit to China with traditional large-scale unit, large electrical network.
Fuel cell is a kind of just in the energy utilization patterns of gradual perfection.Its investment constantly reduces, and the external commercial price of PEMFC is 10000 yuan/kW at present, and the price of PAFC is 21000/kW.It is 10000 yuan/kW that domestic Fu Yuan company announces the price that its PEMFC accepts and order for goods.Other fuel cells are domestic temporary without commercial product.
Fuel cell will have very large development as advanced person's the novel energy, and fuel cell car, electric bicycle etc. will progress into along with rising steadily of oil price market; On the other hand, a large amount of uses of fuel cell-powered and automobile, electric motor car can suppress effectively environment and constantly pollute and greenhouse effects of the earth.Fuel cell is the same with solar cell will be welcomed by the people.
The used metallic catalyst majority of fuel cell is noble metal, causes thus the fuel cell high cost, although fuel cell has many advantages, and, still be difficult to so far large-scale promotion and utilization.The present invention adopts single metal Huo Er ﹑ ternary metal alloy of planting of relative low price as far as possible, can reduce the manufacturing cost of fuel cell, is conducive to the extensive application in every field of fuel cell.
At present, metallic catalyst on the combined electrode of fuel cell adopts spraying more, the technique such as smear, fasten with glue, thus, there are the problems such as the large and skewness of noble metal consumption more, in addition, the metallic catalyst loading also is difficult to effective control, the complex process that more seriously adopts said method to have, and the usefulness of the metallic catalyst that has is low.The present invention adopts electro-plating method, can be simply, quickly and efficiently various metallic catalysts are plated on the combination electrode, and can be by time of electroplating, voltage etc. be controlled, and adopted the advanced advanced materials such as carbon nano-tube film with huge surface area, realize that the aspects such as metallic catalyst loading, catalysis efficiency, combination electrode preparation technology reach advanced level.Adopt the voluntarily fuel cell test device of research and development, satisfied the needs of fuel battery performance test.
