Description
Technical field
The present invention relates to energy battery fields, and in particular to a kind of fuel cell bipolar plate structure.
Background technique
Proton Exchange Membrane Fuel Cells (PEMFC) is that a kind of chemical energy in fuel by chemical reaction is converted into electric energy
Power generator, have many advantages, such as high power density, low environment pollution, fixed power source, electric vehicle, military special type power pack can
It has broad application prospects in terms of with dynamic power supply, causes the attention of more and more national and enterprise.Currently, having become both at home and abroad
PEMFC is applied on manned bus and car to function.
Although the basis at present in relation to PEMFC has made significant progress with application study, still have quite from commercialization
Distance, cost and service life are key restriction factors.Bipolar plates are one of core components of fuel cell, account for entire battery weight
70% ~ 80% and cost 45% or more, play very important effect in terms of the cost and weight for controlling entire battery.Cause
This, exploitation be easily achieved the light-duty of large-scale production, thin layer bipolar plates for improve pile specific power, reduce pile cost, into
And PEMFC commercialization tool is pushed to have very important significance.
Bipolar plates have the function of to be isolated and evenly distribute reaction gas, collect simultaneously derived current, each monocell of series connection etc..
Its material mainly includes metal material, graphite material and composite material.Since graphite type material has good electric conductivity and change
Stability is learned, is the plate material that current PEMFC is widely used.But graphite material is crisp, poor air-tightness, mechanical strength is low and adds
Expenses of labour with it is high the disadvantages of be not easy to be mass produced, limit its industrial applications.Compared with graphite material, metal material has machine
Tool intensity height, good conductive and heating conduction, while being easy to be processed to thin plate, the specific energy of pile can be increased substantially,
Make the bipolar plate material of great competitiveness.
Bipolar plates are also not quite similar due to plate material difference, design.Graphite bi-polar plate is usually by hydrogen plate and oxygen plate
Composition, the flow field of cooling water is to be combined to be formed by the flow field of hydrogen plate and oxygen backboard portion.Flow field depth of cooling water etc. can basis
It is required that processing to obtain by the way of machine milling or pressing mold.Thus, the flow resistance of cooling water can control in lesser range.
When using other corrosion resistant thin metal materials, pole plate processing is carried out using the mechanical technology of punching press.In order to reduce pile weight
Amount, identical as graphite plate, metal double polar plates can be formed using two, three or more metal plates combines.Two metal plates
The flow field of cooling water be composed of the back side of hydrogen plate and oxygen plate, and the bipolar plates of three or more metal plates combines are then
There is individual coolant pole plate.But three or more metal double polar plates combinations are since quantity of polar plate is more, thus pole plate
Weight and volume it is larger, than two pole plate combinations of gravimetric specific power of pile are low by 25% or more, volumetric specific power low 40%
Left and right.Two pole plate combinations are compared with three and the above quantity pole plate combination is complicated in structure, and difficulty of processing is larger.
Since metal plate is process using Sheet Metal Forming Technology, thus the pole plate back side cannot pass through the flow field that secondary operation forms cooling water,
The flow field and water conservancy diversion field of coolant are made of the back side runner of two pole plates.Due to the limitation of metal material itself, polar plate flow field
Groove depth generally will not too deep (< 0.75mm), especially lead flow field portion.The flow field for causing each medium of fuel cell is deep
Spend shallower, resistance of the medium in each flow field increases, and increases distribution difficulty and system energy consumption of the medium in flow field.
Summary of the invention
The purpose of the present invention is to provide a kind of fuel cell bipolar plate structures, using multiple reducing agent pole plates, multiple oxygen
Agent pole plate and Multilayer Film Electrode component form above-mentioned fuel cell bipolar plate structure.The bipolar plate structure that the present invention designs can
The cavity reasonably formed using reducing agent pole plate, oxidant pole plate, is provided flowing flow field for coolant, can be realized two
Coolant enters active region in substrate in combination；Coolant is dexterously introduced into water conservancy diversion region by coolant water conservancy diversion runner simultaneously
