Abstract
The invention relates to a fuel battery dual electrode plate, which comprises the upper and lower adhered electrode plates, whose surfaces have guide grooves and the guide holes through said two electrode plates. The guide groove is connected to the guide hole; the adhesive surface on the electrode plate along the edge of guide groove and hole has the groove to avoid overflow of pastern and jamming the guide groove and the guide hole. After setting the grooves at the edge of guide hole and guide groove, when sticking the electrode plates, the left pastern can flow into the groove by the extrusion to avoid it flowing into guide hole or guide groove in present technique, which will affect the normal operation. The plated pastern can be increased to improve the adhesive reliability and sealing property, improve the pass percent of product, reduce the demand to operator and simplify the operation.
Description
One, technical field
The present invention relates to a kind of fuel cell, specifically a kind of fuel battery double plates.
Two, background technology
Fuel cell is a kind of device that the chemical energy of hydrogen and oxygen is directly changed into electric energy by electrode reaction.The maximum characteristics of this device are owing to do not relate to burning in the reflection process, therefore its energy conversion efficiency is not subjected to the restriction of " Carnot cycle ", the efficient of the fuel cell of most of type is up to 50%-60%, by second use to waste heat, gross efficiency can be up to 80%-85%, as power source, the 2-3 that its actual efficiency of energy utilization is an ordinary internal combustion engine doubly.Produce to pollute hardly in its course of work, power bracket from several watts to the number megawatts, range of application is very wide.The type of fuel cell has multiple, the advantage that wherein Proton Exchange Membrane Fuel Cells has low-temperature operation, starts fast, power density is high, be acknowledged as the most promising, energy replace internal combustion engines, storage battery become the ideal power source and the military civilian portable power supplies of electric automobile, and market is very extensive.
The Proton Exchange Membrane Fuel Cells monomer mainly comprises membrane electrode and pole plate.The centre of battery cell is a membrane electrode, is made up of proton exchange membrane and gas diffusion layers, catalyst, and the membrane electrode both sides are pole plates, and the electronics that electrochemical reaction generates can lead to external circuit by pole plate.The pod apertures and the guiding gutter of plate provide hydrogen fuel, and it is oxidant that cathode plate then provides air.Produce hydrogen cation (proton) in anode hydrogen gas through catalytic reaction, proton exchange membrane helps the hydrogen cation to move to negative electrode.Oxygen in cathode air obtains electronics through catalytic reaction and forms anion, the hydrogen cation water generation reaction of coming with migration.In whole electrochemical reaction, the electric current that pole plate is drawn is the generating result of fuel cell just.A plurality of battery cells are connected as required, form the battery pack (pile) of different capacity.In battery pack, the pole plate overlapped in series, its one side is as the anode guide face, and another side can be used as the cathode diversion face of adjacent monomer battery, and this pole plate is called bipolar plates.Also have a kind of bipolar plates to be bonded by two yin, yang pole plates, the cooling launder of air or water is made in middle abutting edge.When bonding bipolar plates, when paste on special plane bigger on some pole plates, because of the more meeting of viscose glue since push overflow to around, be easy to stop up the hole on the pole plate, as pod apertures or location hole, and guiding gutter, influence the normal performance of fuel battery performance.
Three, summary of the invention
1, goal of the invention: the purpose of this invention is to provide a kind of simple in structurely, can effectively prevent the fuel battery double plates of viscose glue plugging hole and guiding gutter.
2, summary of the invention: the present invention is achieved through the following technical solutions above-mentioned purpose:
A kind of fuel battery double plates, comprise two pole plate bodies that are pasted together up and down, be provided with the pod apertures of guiding gutter and two pole plate bodies of perforation on the surface of two pole plate bodies, guiding gutter communicates with pod apertures, it is characterized in that: be provided with at the periphery of the stickup face upper edge guiding gutter of pole plate body and pod apertures and prevent that viscose glue from overflowing and stopping up the groove of guiding gutter and pod apertures.
When bonding bipolar plates, in order to improve sealing and bonding reliability, must all be coated with uniformly at each adhesive surface and spread an amount of viscose glue, the bonding very little unreliable and sealing property decline of viscose glue; Viscose glue is too many, then makes viscose glue overflow pod apertures and the guiding gutter that stops up on the bipolar plates easily.But, can not accurately guarantee the spread of every bipolar plates owing to the restriction of technology and operating personnel's level of skill.When prevent the groove that viscose glue spills in setting around pod apertures and the guiding gutter after, can increase spread in right amount, reliability and sealing that bipolar plates is bonding had both been guaranteed, even unnecessary viscose glue is arranged simultaneously, it also can flow in the groove when two pole plates are fitted extruding, avoid occurring flowing into pod apertures or guiding gutter, influence the phenomenon of its operate as normal.
In addition,, on two pole plate bodies, also be provided with the location hole that connects two pole plate bodies, for the same reason, also be provided with the groove that prevents that viscose glue from overflowing at the periphery of location hole for the needs that bipolar plates is installed.
According to the difference of hole, trench pattern on the bipolar plates, groove is arranged on apart from guiding gutter, pod apertures or location hole 1-10 millimeter place.
The degree of depth of groove can be between the 0.2-0.5 millimeter, and width can be between the 0.5-1.0 millimeter, when the adhesive surface area bigger, spread more for a long time, the degree of depth of groove and width can suitably amplify, the adhesive surface area is less, spread is opposite.
3, beneficial effect: the present invention compared with prior art has the following advantages: (1) hole and guiding gutter on pole plate body stickup face is provided with groove on every side, when bonding bipolar plates, unnecessary viscose glue can flow into groove when two pole plates are fitted extruding, absorbed by groove, avoided occurring viscose glue ostium or guiding gutter in the prior art, influenced the phenomenon of its operate as normal; (2) spread can suitably increase, and has guaranteed reliability and sealing that bipolar plates is bonding, has improved the qualification rate of product; (3) reduced requirement, made operation simpler operating personnel's technical ability.
Four, description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation that the pole plate body is pasted the face upper groove.
Five, embodiment
A kind of fuel battery double plates as depicted in figs. 1 and 2, comprise two pole plate bodies 1 that are pasted together up and down, on the stickup face 4 of two bodies 1, be provided with the pod apertures 3 and the location hole 6 of guiding gutter 2 and two pole plate bodies 1 of perforation, guiding gutter 2 and pod apertures 3 communicate and are used to the reacting gas that circulates, and location hole 6 is used for the installing and locating of bipolar plates.Viscose glue overflows and stops up guiding gutter 2, pod apertures 3 and location hole 6 and influences its operate as normal in order to prevent to paste bipolar plates, is provided with the groove 5 that prevents that viscose glue from overflowing at the periphery of stickup face 4 upper edge guiding gutters 2, pod apertures 3 and the location hole 6 of this pole plate body 1.Groove 5 adopts the loop configuration of sealing, and the distance that is arranged on guiding gutter 2, pod apertures 3 and location hole 6 is 1～10 millimeter place.During machined grooves 5, its degree of depth can be between 0.2～0.5 millimeter, and width can be selected between 0.5～1.0 millimeter; When the adhesive surface area bigger, spread more for a long time, the degree of depth of groove 5 and width can suitably amplify; The adhesive surface area is less, and spread is opposite.
