Abstract
The utility model discloses a proton exchange membrane fuel cell bipolar plate, it includes that the gaseous reaction of metal sheet is regional, gas feed, gas outlet, be equipped with the recess around the gaseous reaction region above and below the metal sheet respectively, be provided with the dark pore between gas feed, gas outlet and the gaseous reaction region respectively. The utility model discloses improve the leakproofness of group battery, prolonged battery life, improved the battery performance to easy assembly.
Description
The utility model relates to the bipolar plates of a kind of fuel cell, particularly Proton Exchange Membrane Fuel Cells.
At present, existing dual polar plates of proton exchange membrane fuel cell is by metallic plate, gas reaction area, and gas feed and outlet etc. constitute.The two sides of metallic plate is provided with gas reaction area, and one side is the hydrogen reaction zone, and another side is the oxygen reaction zone, and metallic plate has four pores for four jiaos.When described bipolar plates is combined into battery pack, described bipolar plates two sides periphery is coated one deck have reducing agent and oxidant rubber gasket, form the hermetically-sealed construction of battery pack.Because the sealing effectiveness of this hermetically-sealed construction is relatively poor, causes battery pack can not effectively separate gas, form reducing agent and oxidant problem such as collaborate easily, have a strong impact on battery performance.
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of and can effectively separate two kinds of gases, improves battery pack air seal effect, prolongs the battery dual polar plates of proton exchange membrane fuel cell in useful life.
The purpose of this utility model is achieved by following proposal:
Dual polar plates of proton exchange membrane fuel cell of the present utility model comprises the metallic plate gas reaction
Zone, gas feed, gas vent, described metallic plate above and below gas reaction area
Be respectively equipped with groove, described gas feed, gas vent and gas reaction area around the territory
Be respectively arranged with dark duct between the territory.Muscle between being provided with in the described sealed groove.
Below in conjunction with drawings and Examples the utility model is described in further detail:
Fig. 1 is a schematic appearance of the present utility model;
Fig. 2 is a cutaway view of the present utility model.
In the drawings, four jiaos of metallic plate are provided with four circular holes, are respectively hydrogen inlet 1, hydrogen outlet 2, oxygen inlet 3, oxygen outlet 4.Upper and lower two faces of metallic plate are respectively arranged with the hydrogen reaction zone 8 and the oxygen reaction zone 9 of concavo-convex groove.Two holes are set between gas inlet and outlet side and gas reaction area carry dark hole 6 and the dark hole 7 of oxygen delivery as hydrogen.Be provided with interband muscle location seal groove 5 around the gas reaction area, make hydrogen, enter hydrogen reaction zone 8, discharge from hydrogen outlet 2 again through carrying dark hole 6 by hydrogen inlet 1; Oxygen enters oxygen reaction zone 9 from oxygen inlet 3 through the dark hole 7 of oxygen delivery, discharges from oxygen outlet 4 again.
Compare with the plane formula bipolar plates of prior art, the beneficial effect of groove type bipolar plates of the present utility model is as shown in the table:
| Bipolar plate structure | Compressive resistance | The assembling complexity | The fitting tight success rate |
| Plane formula | Less than 0.2 MPa | Difficult assembling | 10％～20％ |
| Groove type | Greater than 0.5 MPa | Easily assembling | 95％～100％ |
By table as seen, groove type bipolar plates performance obviously is better than plane formula structure bipolar plates.It is relatively poor that it has solved plane formula bipolar plates gas tightness effectively, and problem such as collaborate has easily guaranteed that battery pack has good sealing property, has prolonged battery life, has improved battery performance, and assembling easily.
Claims (2)
1. dual polar plates of proton exchange membrane fuel cell, comprise metallic plate gas reaction area, gas feed, gas vent, it is characterized in that, be respectively equipped with groove around the gas reaction area of described metallic plate above and below, be respectively arranged with dark duct between described gas feed, gas vent and the gas reaction area.
2. dual polar plates of proton exchange membrane fuel cell according to claim 1 is characterized in that, muscle between being provided with in the described sealed groove.
