Abstract
The utility model provides a hot pressing mold for massive production of membrane electrodes. When the hot pressing mold is adopted for massive production, the working hours and the raw materials are saved, and para-position is exact among five parts of the membrane electrode structure, and the performance is stable. The utility model is characterized in that the hot pressing mold comprises a lower frame plate and an upper frame plate, wherein lower frame openings are evenly distributed on the upper surface of the lower frame plate, and upper frame openings are evenly distributed on the lower surface of the upper frame plate, and the upper frame openings and the lower frame openings are the same in size and quantity, and correspond to the same position in the vertical direction.
Description
Technical field
The utility model relates to the production technical field of membrane electrode, is specially the hot pressing die that a kind of membrane electrode is produced in batches.
Background technology
Film electrode structure comprises five parts: middle solid-state proton exchange membrane, anode catalyst layer and cathode catalysis layer and the outermost anode gas diffusion layer and the cathode gas diffusion layer of proton exchange membrane both sides, that is, Catalytic Layer always places between proton exchange membrane and the homonymy gas diffusion layers.
Based on the said structure of membrane electrode, its preparation method generally has two kinds:
First kind is the technology of coated catalysts hot repressing on film: promptly earlier at the both sides of a slice proton exchange membrane difference coated anode Catalytic Layer and cathode catalysis layer, prepare a slice anode gas diffusion layer and a slice cathode gas diffusion layer more respectively, the back hot pressing that at last proton exchange membrane, the cathode gas diffusion layer of anode gas diffusion layer, coating on both sides Catalytic Layer superposeed successively forms membrane electrode;
Second method is the technology of coated catalysts hot repressing on gas diffusion layers: promptly prepare anode gas diffusion layer and cathode gas diffusion layer respectively, coated cathode Catalytic Layer on coated anode Catalytic Layer, cathode diffusion layer on the anode diffusion layer respectively then, at last, the cathode gas diffusion layer of the anode gas diffusion layer of a slice coated anode Catalytic Layer, a slice proton exchange membrane, a slice coated cathode Catalytic Layer is superposeed successively hot pressing forms membrane electrode.
Adopt above-mentioned two kinds of methods to make membrane electrode, membrane electrode can only be produced in process of production one by one, therefore has a lot of duplications of labour, and work efficiency is very low; In addition, the process that most importantly applies in the production process of membrane electrode, therefore, when a slice a slice was produced membrane electrode, each sheet membrane electrode all will pass through independent coating, and this certainly will cause the difference of performance between the membrane electrode.
China publication number: CN1276633, open day: on December 13rd, 2000 application number: CN00121124.2, the applying date: 2000.07.27, application for a patent for invention title: contain fuel cell of a plurality of membrane electrodes and preparation method thereof on a slice film, a kind of a plurality of membrane electrode preparation method that contain on a slice film are disclosed, it places on a slice proton exchange membrane by the template that will contain a plurality of geometries, geometric figure by template is coated in the Catalytic Layer slurry on the proton exchange membrane then, produces by the method for hot pressing at last and contains the multi-disc membrane electrode on a slice film.
There is following deficiency in this preparation method:
At first, by geometric template coated catalysts slurry is arranged, if guarantee not waste catalyst, then must in a geometry, apply catalyst, coated catalysts in another zone again, its essence still a slice a slice prepares membrane electrode, and therefore a lot of repeating steps are arranged, and wastes man-hour; If save time, and to all geometries coated catalysts simultaneously, promptly regions coated has also comprised the part at intermittence of the template that each geometry is separated, and is self-evident, this certainly will waste a lot of catalyst;
Secondly, disadvantage at coated catalysts on the proton exchange membrane is that proton exchange membrane more or less random contraction distortion can take place in coating procedure, therefore after a face coating is finished, two kinds of situations can take place when the proton exchange membrane upset was applied another face again, promptly, situation 1: film shrinks and causes that each geometry zone of template is greater than the Catalytic Layer zone that has applied, situation 2: the zone of the geometry in the template and the dislocation of the Catalytic Layer that has applied zone, can cause either way that below whole electro-chemical activity zone reduces, thereby waste material, the real output of battery does not reach design load simultaneously;
Once more, the film of, the coated catalysts that do not misplace fully corresponding for the both sides Catalytic Layer, because anode gas diffusion layer is identical with the area of Catalytic Layer with cathode gas diffusion layer, and the coated catalysts caudacoria is opaque, when this also can cause membrane electrode hot pressing, the difficulty of aliging between underside gas diffusion layer and the downside Catalytic Layer, therefore, after the membrane electrode hot pressing, cause easily between the upper and lower sides gas diffusion layers to misplace;
At last, simultaneously on a slice film, during 100 membrane electrodes of hot pressing as many as,, therefore, will cause the assembling difficulty, even can cause the serious consequence that multi-disc membrane electrode upper and lower sides gas diffusion layers all misplaces because the gas diffusion layers of upper and lower sides does not all have positioner.
Summary of the invention
At the problems referred to above, the hot pressing die that the utility model provides a kind of membrane electrode to produce in batches, its mass production is not only saved man-hour, is saved material, and contraposition is accurate between five parts of film electrode structure, stable performance.
The hot pressing die that a kind of membrane electrode is produced in batches, its technical scheme is such:
It is characterized in that: it comprises lower frame sheet, upper ledge sheet, described lower frame sheet upper surface is evenly equipped with the lower frame opening, described upper ledge sheet lower surface is evenly equipped with the upper ledge opening, and described upper ledge opening, the lower frame opening size is identical, quantity is identical and corresponding to the same position of vertical direction.
It is further characterized in that: described lower frame opening runs through described lower frame sheet, and the lower surface pad of described lower frame sheet is equipped with the lower metal sheet;
Described upper ledge opening runs through described upper ledge sheet, and the upper surface of described upper ledge sheet is coated with the upper strata sheet metal.
After adopting mould of the present utility model, the whole anodic gas diffusion electrode that forms that applies, be divided into the small pieces gas-diffusion electrode behind the cathode gas diffusion electrode, with the small pieces gas-diffusion electrode be placed on respectively hot pressing die on, the upper ledge opening of lower frame sheet, in the lower frame opening, on, be placed with the proton exchange rete in the middle of the lower frame sheet, take out after then mold integral being put into hot press hot pressing, form whole Zhang Lianti film electrode structure, cut apart the formation single membrane electrode then, gas-diffusion electrode did not misplace when it can guarantee hot pressing, thereby improved the rate of finished products of membrane electrode production process greatly; Simultaneously because once can many membrane electrodes of hot pressing, have therefore shortened the time of hot pressing greatly; To sum up, it is not only saved man-hour, saves material, and contraposition is accurate between the each several part of film electrode structure, stable performance.
