Description
Technical Field
The utility model relates to a fuel cell technical field, concretely relates to empty board structure of hydrogen for fuel cell.
Background
A hydrogen-air fuel cell is a cell that uses a chemical element, hydrogen, to store energy. The basic principle is the reverse reaction of electrolyzed water, hydrogen and oxygen are supplied to the anode and cathode respectively, and after the hydrogen diffuses out through the anode and reacts with the electrolyte, electrons are released to reach the cathode through an external load.
The electrode plate of the existing hydrogen-air fuel cell is a pure graphite plate or a metal plate assembly, the pure graphite plate is easy to process but is relatively heavy, the pure metal plate is light in weight but needs to be frequently opened during processing and forming, and a large amount of capital investment is needed for opening each mold, so that the difficulty is high, and the cost is high. Traditional company in the past mainly adopts pure graphite plate production preparation, but along with the production of metal sheet in the market, pure graphite plate has not can not well satisfy the market demand, and traditional company needs the reform, but adopts metal sheet development, needs to develop a large amount of moulds, and the cost is higher, how to guarantee pure graphite plate production mould in the past and recycle to and draw close to market metal sheet development, needs a new structure product.
Disclosure of Invention
In order to solve the problem, the utility model provides a empty board structure of hydrogen for fuel cell, design benefit, convenient to use.
The technical scheme of the utility model:
a hydrogen hollow plate structure for fuel cell is composed of graphite plate and metal plate adhered to the graphite plate by adhesive.
The metal plate is one of stainless steel plate, aluminum plate, copper plate, titanium plate and other metal plates.
The graphite plate is a rectangular flaky plate, waist-shaped holes are respectively designed on two sides of the graphite plate, the metal plate is a corrugated plate, the lower end of the metal plate is adhered to the upper surface of the graphite plate through glue, and the metal plate is positioned between the waist-shaped holes on the two sides.
The hydrogen hollow plate structure for the fuel cell further comprises two side sealing blocks, the two side sealing blocks are respectively arranged at two ends of the upper surface of the graphite plate, and the side sealing blocks are also provided with waist-shaped holes which are in one-to-one correspondence with the waist-shaped holes on the graphite plate.
Each side of the waist-shaped hole is respectively designed with two or one or more than two, and the waist-shaped holes are symmetrically designed. One side of the waist-shaped hole at the two sides is a waist-shaped hole which is a carrying hole, and the other side is an air outlet hole.
The graphite plate below design have a plurality of strip recess and graphite plate below be close to all edge position designs all around and have the annular groove, a plurality of strip recess is located between the waist shape hole of both sides, a plurality of strip recess and waist shape hole are located the annular groove inboard.
The utility model has the advantages that adopt graphite cake and metal sheet combined design mode, cost reduction still has the low resistance effect, and the heat conductivity is good.

Detailed Description
Referring to the attached fig. 1-3, a hydrogen blank structure for a fuel cell comprises a graphite plate 1 and a metal plate 2, wherein the lower surface of the metal plate 2 is adhered to the upper surface of the graphite plate 1 by glue.
The metal plate 2 is one of metal plates such as a stainless steel plate, an aluminum plate, a copper plate, a titanium plate and the like.
The graphite plate 1 is a rectangular flaky plate, waist-shaped holes 3 are respectively designed on two sides of the graphite plate 1, the metal plate 2 is a corrugated plate, the lower end of the metal plate 2 is bonded on the graphite plate 1 through glue, and the metal plate 2 is located between the waist-shaped holes 3 on the two sides.
The hydrogen hollow plate structure for the fuel cell further comprises two side sealing blocks 4, the two side sealing blocks 4 are designed, the two side sealing blocks 4 are respectively designed at two ends of the upper surface of the graphite plate 1, and the side sealing blocks 4 are also designed with kidney-shaped holes which are in one-to-one correspondence with the kidney-shaped holes 3 on the graphite plate 1.
Each side of the waist-shaped hole 3 is provided with two or one or more than two, and the waist-shaped holes are symmetrically designed; one side of the waist-shaped hole at the two sides is a waist-shaped hole which is a carrying hole, and the other side is an air outlet hole.
Graphite plate 1 below the design have a plurality of strip recess 5 and graphite plate 1 below near the design of all edge positions all around have annular groove 6, a plurality of strip recess 5 is located between the waist shape hole 3 of both sides, a plurality of strip recess 5 and waist shape hole 3 are located annular groove 6 inboardly.
The utility model discloses during the use, like figure 4, the empty board structure of a plurality of hydrogen superposes in proper order and places together, and carries out the interval through the sealed piece of side between the empty board structure of adjacent hydrogen and seals, and last both ends are pushed down and screw nut subassembly carries out whole locking through the end plate. The utility model discloses a graphite cake and metal sheet combined design mode, cost reduction still has the low resistance effect, and the heat conductivity is good. The production mould of the existing graphite plate is utilized, unnecessary mould opening of the metal plate is reduced, and meanwhile, the product also has the effect that the pure metal plate does not have the effect.
