Description
Technical field
The present invention relates to fuel cell fields, specifically, being related to a kind of super thin metal composite dual-electrode plates and its preparation side
Method and fuel cell comprising it.
Background technique
Fuel cell is a kind of efficient green power generation device, can will directly be stored in fuel such as hydrogen and oxidant such as
Chemical energy in air is converted into electric energy efficient, environmentally friendlyly.Wherein, Proton Exchange Membrane Fuel Cells (PEMFC) has
The advantages that energy-efficient, the operation is stable, running temperature are moderate, the cold start-up time is short, in electrical source of power automobile-used, peculiar to vessel, standby electricity
Source, cogeneration, the special fields such as military have important application prospect.
Currently, how to promote the energy density of PEMFC, production cost is reduced, it is important to be that its large-scale commercial faces
Project.Major measure includes the more inexpensive material of selection, the dosage for reducing material, simplification or changes battery structure, optimization electricity
The production process of pond and its each component simultaneously realizes mass production.
The main component for constituting PEMFC battery pile includes membrane electrode, diffusion layer, bipolar plates, end plate, in these types of component
In, end plate only respectively has two at the pile both ends that tens of or hundreds of monocells are constituted, and membrane electrode is only some tens of pm, the two
Volume only accounts for very small part (about 20%) in entire PEMFC battery pile, and graphite bi-polar used in traditional PEMFC battery pile
Plate thickness is 3-8 microns, and therefore, therefore the overwhelming majority (70-80% or so) that bipolar plates occupy pile volume will reduce
PEMFC volume improves energy density, and preparing bipolar plates thin as far as possible is mostly important measure.Bipolar plates (also known as flow-field plate) are
The core component of fuel cell plays gas barrier, the water conservancy diversion of gas and distribution, conduction, supports the effects of membrane electrode.Generally
Ground, fuel and oxidant enter the fuel cell being assembled by membrane electrode, diffusion layer and bipolar plates, sealing element, require first to lead to
The gas diffusion layers that the flow field crossed in bipolar plates is assigned to enter back into Catalytic Layer and electrocatalytic reaction occur, are converted into electric energy, raw
At water be diffused into gas diffusion layer surface, then fuel cell is discharged by flow field.
Traditional PEMFC bipolar plates are to be formed on graphite tabula rasa by machining engraving runner, due to graphitic crisp, machine
Tool limited strength, therefore the size of the groove and ridge in the thickness of graphite bi-polar plate and the flow field carved on it is all larger, exists more
Several millimeter magnitudes, therefore cause pemfc stack both thick and again, energy density is low.Later, people are by graphite or carbon material and tree
Mold casting forming method is used after rouge mixing, directly preparation is adapted only to the Composite Double plate of runner though manufacturing cost can be reduced
Produce in enormous quantities, simultaneously because mold and preparation process problem, this molding bipolar plate runner width cannot be made narrow, exist more
400 microns or more, meanwhile, the pole plate of this technique preparation is limited by the strength of materials, cannot also be made thin, integral thickness is only
2-4 millimeters can be reduced to.
Another bipolar plate material is metal double polar plates, is mostly struck out with stainless steel or titanium-alloy thin-plate with flow path portion
Part, then assemble bipolar plates by being bonded or welded technique with other component, this method also can with large scale preparation, but technique compared with
It is increasingly complex.And initial stage, to prepare mold investment huge, and is limited by mould and die accuracy, thickness is also only capable of at 1-2 millimeters or so, and
And how to control the stress in metal sheet forming process, deformation and a very big problem.
In a fuel cell, the size of runner plays a significant role battery performance, and countries in the world are newly developed in recent years sets
In the flow-field plate of meter in place of more or less Shortcomings.Such as the water that the air flow method of flow-field plate is not uniform enough, reaction generates is easy
Accumulation is not easy to be discharged, flow field structure design easily causes the excessively high influence battery operation performance of reaction dead zone, membrane electrode local temperature.
In general, runner is narrower, and effective workspace inner flow passage is narrower, and gas distribution and heat transfer are more uniform, and battery can obtain
Higher current density.And the metal double polar plates of the composite graphite plate or punching press molded, because being limited by mould and die accuracy, width of flow path
It can only achieve 0.3-1.0 millimeter magnitude mostly, be still difficult to meet battery request.
