Abstract
The utility model discloses a fuel cell metal bipolar plate of carbon is plated on surface, including metal veneer (10), metal veneer (10) quantity is two, and metal veneer (10) one side is provided with gas flow field (11), and the another side is provided with coolant liquid flow field (12), and the carbon -coating has been plated on metal veneer (10) gas flow field (11) surface, and coolant liquid flow field (12) surface coincidence that two nuggets belong to veneer (10) connects to form metal bipolar plate, plates the carbon -coating through the surface, makes bipolar and the acid aggressive fume of metal, liquid keep apart, thus reduce right the metal bipolar plate problem that life does not grow because corrode under acid environment under the prior art has been solved in metal bipolar plate's corruption to solve the problem that graphite bipolar plate thickness is too big, manufacturing cost is too high, mainly be applied to the high temperature fuel cell bipolar plate that fuel cell bipolar plate, especially operational environment are high temperature strong acid.
Description
Technical field
The utility model relates to fuel battery metal double polar plate field, particularly relates to a kind of fuel battery metal double polar plate of plated surface carbon.
Background technology
Current fuel cell bipolar plates used mainly graphite bi-polar plate, part of fuel battery adopts metal double polar plates, and graphite bi-polar plate price is high, and thickness is large, is unfavorable for the marketization and the miniaturization of fuel cell; And metal double polar plates cannot have the longer life-span in the sour environment of fuel cell.Particularly, in high-temperature fuel cell, metal is more easily corroded, and affects Performance data and life-span.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of fuel battery metal double polar plate of plated surface carbon.
The utility model is the technical scheme that its technical problem of solution is taked: a kind of fuel battery metal double polar plate of plated surface carbon, comprise metal veneer, described metal veneer quantity is two pieces, described metal veneer one side is provided with gas flowfield, another side is provided with cooling fluid flow field, described metal veneer gas flowfield surface is coated with carbon-coating, and the cooling fluid flow field face of two pieces of described metal veneers overlaps and connects to form described metal double polar plates.
Further, the carbon thickness of coating on described metal double polar plates is even, and gauge is in 100 nanometer to 1000 nanometers.
Further, two pieces of said metal veneer connected modes are for being welded to connect.
The operation principle of the technical program is: described carbon coating covers the surface in described metal double polar plates flow field, make metal double polar plates flow field face completely and fuel cell inner acidic environment, thus the corrosion that reduction metal double polar plates receives in fuel cell, increase the life-span of metal double polar plates.
The beneficial effects of the utility model are: make described metal double polar plates completely cut off sour environment by the plated surface carbon of described metal double polar plates, thus reduce the corrosion of metallic matrix, increase the useful life of described metal double polar plates, and then increase the life-span of the fuel cell using described metal double polar plates.Meanwhile, metal when reducing bipolar plates thickness, can ensure the intensity of bipolar plates as bipolar plates matrix, thus reduces the volume of fuel cell unit.
Accompanying drawing explanation
Fig. 1 is the metal double polar plates schematic diagram of a kind of embodiment of the utility model.
The implication marked in figure: 10. metal veneer, 11. gas flowfields, 12. cooling fluid flow fields.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
In embodiment illustrated in fig. 1, comprise metal veneer 10, metal veneer 10 quantity is two pieces, metal veneer 10 one side is provided with gas flowfield 11, another side is provided with cooling fluid flow field 12, metal veneer 10 gas flowfield 11 surface is coated with carbon-coating, and the surface, cooling fluid flow field 12 of two pieces of metal veneers 10 overlaps and connects to form metal double polar plates.
In the utility model embodiment, the carbon thickness of coating on metal veneer 10 is even, and gauge is in 100 nanometer to 1000 nanometers.
In the utility model embodiment, two pieces of metal veneer 10 connected modes are for being welded to connect.
The operation principle of the utility model embodiment is, metal veneer 10 surface is coated with carbon-coating and is covered completely on gas flowfield 11 surface, assembles afterwards, thus form fuel cell unit with the fuel cell module such as membrane electrode.The matrix of metal veneer 10 does not occur directly to contact because of the isolation of plated carbon-coating with the sour environment of fuel battery inside, thus avoids corrosion of metal problem.And carbon-coating is due to itself corrosion resistant characteristic, the sour environment of fuel battery inside can be applicable to for a long time, thus increase the life-span of fuel cell, and owing to using metal as the matrix of bipolar plates, greatly can reduce the thickness of bipolar plates, thus reduce the volume of fuel cell.
The beneficial effects of the utility model are: by the gas flowfield 11 plated surface carbon-coating at metal veneer 10, metallic matrix is avoided to contact with the direct of sour environment, and then reduce the corrosion of metallic matrix, thus increase the useful life of described metal double polar plates, increase the life-span of the fuel cell using described metal double polar plates.
The above is only the utility model description preferred embodiment; should be understood that the finiteness due to literal expression; and objectively there is unlimited concrete structure; for this area those skilled in the art; under the premise without departing from the principles of the invention; can also make some improvement, these improvement also should be considered as the scope of protection of the invention.
