Description
[technical field]
The present invention relates to a kind of bipolar plates of fuel cell, a kind of specifically bipolar plates that is used for Proton Exchange Membrane Fuel Cells.
[background technology]
Fuel cell is a kind of electrochemical appliance, and its battery cell is that (negative pole is promptly imported the electrode of fuel, anode by positive and negative two electrodes; The anodal electrode of promptly importing oxidant, negative electrode) and the electrolyte composition.The active material of different is general battery is stored in inside battery, therefore, has limited battery capacity.And the positive and negative electrode of fuel cell itself does not comprise active material, just a catalytic converter element.Therefore fuel cell is the energy conversion that chemical energy is converted into electric energy worthy of the name.When battery operated, fuel and oxidant are supplied with by the outside, react.Usually by the fuel electrodes (anode) of electrolyte panel that forms ionic conductor and the configuration of its both sides and air pole (negative electrode), and both sides gas flow path formation, the effect of gas flow path is that fuel gas and air (oxidant gas) can be passed through in stream to fuel cell main body.As long as reactant is constantly imported, product is constantly got rid of in principle, and fuel cell just can generate electricity continuously.In addition, have only fuel cell main body to work, the corresponding auxiliary system of a cover must be arranged, comprise reactant supply system, heat-extraction system, drainage system, electrical property control system and safety device etc.
Bipolar plates generally occupies the 70%-80% of pile weight, and it is about 60% to occupy production cost, and its major function that should possess has: isolate fully and the uniform distribution battery in fuel and oxidant; Good electrical conductivity can be collected and conduction current; Good thermal conductance, effectively cool batteries group; Transmission generates water, moisture; Realize the connection of the monocell in the battery pack.All there are the technical problem that many urgent needs solve in bipolar plate material, flow field structure, especially processing cost at present.
