Description
Technical field
The present invention relates to a kind of preparation method of hydrogen fuel cell membrane electrode.
Background technology
Hydrogen fuel cell take hydrogen as fuel, chemical energy is directly converted to the Blast Furnace Top Gas Recovery Turbine Unit (TRT) of electric energy, have quick startup, can the feature such as high, the environmental friendliness of room temperature-operating, simple, the theoretical specific energy density of structure, be especially suitable for use as compact power, electric motor car power electric source capsule dispersion power station etc., have broad application prospects.
Membrane electrode is the core component of hydrogen fuel cell, and its performance quality directly affects performance and the stability of battery.Membrane electrode is made up of proton exchange membrane and the catalyst layer respectively in these proton exchange membrane both sides and gas diffusion layers usually, catalyst layer is the important place of hydrogen fuel cell generation electrochemical catalysis reaction, therefore, its catalytic efficiency determines the performance of fuel cell to a great extent.The key improving catalyst layer catalyzes efficiency is the three-phase reaction interface that will increase nano-noble metal catalyst particle surface and reacting gas, proton and electronics.Particularly, hydrogen reaction gas arrives noble metal catalyst particles surface by gas passage, through catalytic reaction, produce proton and electronics, the proton produced needs to be transmitted to proton exchange membrane direction by the proton channel of the proton conductor network struction in catalyst layer, the conductive network directional later exhaust diffusion layer that electronics is then built by catalyst carrier, if there is a passage obstructed, then electrochemical reaction of fuel battery will be obstructed.But conventional membrane electrode assembly preparation is difficult to form good three phase boundary between catalyst and proton exchange membrane, this reduces the utilance of catalyst, increases the consumption of catalyst, reduce the performance of battery.In order to improve the performance of fuel cell membrane electrode, the utilance of catalyst need be improved.Simultaneously due to proton exchange membrane easily damage, the feature such as not easy to operate, make the preparation technology of membrane electrode become complicated, reduce the continuous prodution of membrane electrode, improve technique preparation cost.
Catalyst is mainly transferred on diffusion layer and is formed Catalytic Layer by traditional method for preparing membrane electrode, then diffusion layer, Catalytic Layer, proton exchange membrane is forced together through HTHP by heat pressing process, is prepared into membrane electrode.But this kind prepares the method for Catalytic Layer, catalyst feed leaks in the hole of diffusion layer unavoidably, has both affected the pore structure in diffusion layer, again reduces the utilance of catalyst, is difficult to reduce fuel cell cost.Adopt this kind by diffusion layer, the method for Catalytic Layer together with proton exchange membrane hot pressing, improve difficulty of processing, the rate of finished products of battery is low, and product is single simultaneously.
Along with the development of technology, after the nineties in 20th century, people attempt directly Catalytic Layer being applied in proton exchange membrane, namely proton exchange membrane core component CCM (catalyst coated membrane) is prepared, this method can improve the utilance of catalyst, reduces the loading of Pt further.Catalyst granules is directly contacted with film by Nafion ion, thus improves proton-conducting, and CCM technology maintains original gap structure, and gas is spread and is more prone to, the MEA that MEA Performance Ratio obtained like this uses conventional method to obtain increases.
US Patent No. 5211984, US6847518 disclose a kind of transfer printing and prepare membrane electrode, Chinese patent CN1560949, CN1862855 also have similar approach, catalyst slurry is first coated onto on transfer medium by described method, after drying, two panels is scribbled anode, the transfer medium of cathod catalyst and the hot pressing of a slice proton exchange membrane respectively, after peeling off transfer medium, obtain membrane electrode assembly.Catalytic Layer obtained by the method is thinner; reduce the consumption of catalyst; Catalytic Layer and proton exchange membrane have good contact; decrease the impact of solvent on proton exchange membrane; the monocell of assembling has higher power density, but its weak point is that temperature and pressure is on film and have impact to catalyst adhesive strength on film and be difficult to control, and when hot pressing; the edge that film contacts with transfer medium, due to discontinuity, usually can be destroyed.In addition, in transfer process, because hot pressing makes partially catalyzed agent be bonded on transfer medium, the utilance of catalyst is declined, and meanwhile, transfer medium often can not reuse because hot pressing deforms, and increases preparation cost, whole complex technical process.
Chinese patent CN1838456N adopts direct spraying legal system for fuel cell membrane electrode, fixed frame is adopted to fix proton exchange membrane, this proton exchange membrane is through preliminary treatment, then volatilize in spraying process with the solvent of infrared lamp and mercury lamp promoting catalyst slurry, slurries are sprayed on the both sides of film respectively, with vacuum treatment, solidification Catalytic Layer, but still can not effectively solve the swelling of proton exchange membrane, and the Catalytic Layer after cryogenic vacuum process is easier to depart from proton exchange membrane, reduce the useful life of electrode.
Chinese patent CN200610035275.4 discloses a kind of method that direct spraying prepares fuel cell membrane electrode, after described method comprises proton exchange membrane preliminary treatment, be fixed in a film fixture, then under light illumination catalyst slurry is painted on the two sides of proton exchange membrane, obtains through low-temperature vacuum drying.The obtained membrane electrode of the method solves the swelling problem of proton exchange membrane, but due to through low-temperature vacuum drying process, complex process will will be there is after spraying, deficiency not easy to operate, manufacturing cycle is long to proton exchange membrane preliminary treatment.
Chinese patent CN200810024885.3 provides a kind of preparation technology of membrane electrode of fuel batter with proton exchange film, described method is for adopting adhesive tape or rubber slab by proton exchange membrane Four built in boundaries, fix proton exchange membrane at relatively high temperatures, solve the swelling problem of proton exchange membrane.In the spraying process of membrane electrode, by regulating the evaporation rate of catalyst slurry, the heating-up temperature of proton exchange membrane, control the swelling of proton exchange membrane, make catalyst even application on film, improve that proton exchange membrane in preparation process is swelling, crumple, catalyst amount cross high deficiency, but weak point film is fixed film device and is too relied on manual operation, swelling could the taking off with fixed head of proton exchange membrane need be tied up with solvent, there is Catalytic Layer contraposition to be forbidden, complex process and production efficiency low wait not enough.
