Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, below In conjunction with detailed description of the invention, this utility model is expanded on further.
The concrete hot pressing die that this utility model relates to refers to have certain thickness and the flat board of the 2-4 that slots, in groove 2-4 Having the adsorption hole 2-2 of certain size and quantity, the boundary at groove 2-4 is carved with scale in order to determine the three dimensions of membrane electrode Position;In order to block the flat board plug 3 of adsorption hole 2-2;In order to form absorption cavity and provide the cover plate 4 of hot pressing plane, concrete Case is implemented as follows.
One, concrete size, parameter and the effect of fluting flat board 2: fluting flat board 2 thickness 15mm, housing size 400mm* 400mm, the size of groove 2-4 need to be less than housing size, and this utility model uses 350mm*350mm, then frame 2-1 a size of 50mm It is 1mm that width is carved with the length scales precision of 300mm, has equidistant adsorption hole 2-2 in groove 2-4, and the area of adsorption hole 2-2 is originally Utility model uses the diameter 2mm of 300mm*300mm, adsorption hole 2-2, and center of circle spacing 4mm in hole, hole depth 5mm, at frame 2- The side of 1 has the hole of the adaptor connecting vacuum pump, and adaptor quick connector 2-3 connects PTFE hard tube and is connected to vacuum Pump.
Two, the concrete size of flat board plug 3 and parameter and effect: flat board plug 3 mainly has two effects at this utility model, 1, Play when adsorption and diffusion layer blocking other unnecessary hole increase binding force, 2, when hot pressing block membrane electrode part hole, play Protective effect to membrane electrode.The size of flat board plug 3 can arbitrarily regulate but be no more than the area of adsorption hole 2-2, this practicality The flat board plug 3 of novel employing 300mm*300mm size, flat board plug 3 refers on the flat board of thickness 2mm with equally spaced cylinder Body 3-1, the basal diameter of cylinder 3-1, spacing, highly desirable corresponding with adsorption hole 2-2, it is necessary to assure flat board plug 3 can be complete In full insertion hole, the cylinder 3-1 base diameter that the present embodiment uses is 1.95mm (less than the 2mm in hole), cylinder 3-1 circle In the heart away from being highly 5mm (identical with hole depth) for 4mm, cylinder 3-1, the boundary of each independent flat board plug 3 is from The center of circle distance of the cylinder 3-1 in outside is 2mm, so can ensure that two flat board plug 3 coupling parts can ensure that seamless company Connect.
Three, the design parameter of cover plate 43 and size and effect: this utility model that acts on of cover plate 4 mainly has two, 1, Absorption cavity is formed together with fluting flat board 2 when adsorption and diffusion layer, 2, play the work of fixed flat planar plug 3 when hot pressing membrane electrode With, its size needs corresponding with the size of fluting sheet groove so that cover plate 4 can cover groove 2-4 completely, and this utility model uses A size of 345mm*345mm, thickness is 6mm, and needs to be covered with high 2-3mm close of an a width of 30mm at cover plate 4 edge Envelope rubber blanket 4-1 (natural resiliency cause its highly can be little higher), has ventilation gully 4-2, ridge in the inside of cover plate 4 High 2mm (the cover plate 6mm+ ridge height 2mm+ flat board plug thickness 2mm+ deep 5mm of adsorption hole 2-2 should be equal to 15mm--slab-thickness), ridge width 10mm, the long 300mm of ridge.
Hot-press method concrete during experiment is as follows: (1) determines the membrane electrode size of hot pressing, is built by groove 2-4 with cover plate 4 Form absorption cavity, upset fit (action of lid is to take up cover plate (4) to cover downwards groove, now adsorption function face under Side, needs to turn so that adsorption hole upwards by the zoarium of the two, at this time could spread carbon paper<according to coordinate setting>), make Diffusion layer upward, is placed on adsorption hole 2-2 by adsorption hole 2-2, determine place coordinate (general we with plane system coordinate [x, Y] two diagonal angles of diffusion layer, location or other active positions), open vacuum pump, diffusion layer fixed, after then sealing CCM (catalyst coat film) continue to place, determine placement coordinate (location with diffusion layer as), it is ensured that in diffusion layer and CCM Effective area (containing the part of catalyst, this part plays the effect of catalytic gas reaction thing, needs and carbon paper (diffusion layer) Corresponding) overlap;(2) take the mutually isostructural fixture of another one (or referred to as lower mold), diffusion layer is placed on and in step (1) In diffusion layer same coordinate, open vac sorb;Then by step (1), (2) fixture altogether, pass through with standing screw 1-1 The location, hole, location at four angles of mould, it is ensured that upper/lower die (i.e. the anode and cathode diffusion layer of fuel cell) is in the same space position On, the standing screw 1-1 in hole, four location is locked by lock nut 1-2;(4) vacuum pump is closed, by upper and lower two moulds Cover plate 4 is taken away, and adsorption hole 2-2 covers with flat board plug 3 (preventing hot pressing is that be not the stressed diffusion layer structure that causes of bore portion is broken Bad), cover cover plate 4, remove standing screw 1-1, the flat plate mold of above-mentioned composition is taken hot pressing on hot press.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.One's own profession Skilled person will appreciate that of industry, this utility model is not restricted to the described embodiments, described in above-described embodiment and description Principle of the present utility model is simply described, on the premise of without departing from this utility model spirit and scope, this utility model is also Have various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model Claimed scope is defined by appending claims and equivalent thereof.
