Description
Technical field
The present invention relates to field of batteries, in particular to a kind of fuel-cell device.
Background technology
Fuel cell is a kind of environmental friendliness, efficient, long-life TRT.With Proton Exchange Membrane Fuel Cells
(PEMFC) as a example by, fuel gas is entered from anode-side, and hydrogen atom loses electronics and becomes proton in anode, and proton is handed over through proton
Change film and reach negative electrode, negative electrode is also reached via external circuit during electron synchrotron, and generation is combined with oxygen in negative electrode proton, electronics
Water.Chemical energy is converted into electric energy by fuel cell using on-fuel mode, is directly sent out due to not limited it by Carnot cycle
Electrical efficiency may be up to 45%.With battery pile as core TRT, fuel cell system is integrated with the moulds such as power management, heat management
Block, with the feature that heat, electricity, water, gas are managed as a whole.Fuel cell system product from fixed power station, to portable power supply；From
Electric automobile, to spaceship；From military hardware, have a wide range of applications space to the product for civilian use.
In existing fuel cell structure, generally bipolar plates are overlapped successively with membrane electrode, form more piece even tens of
The battery pile of section, the TRT higher so as to form power.As shown in figure 1, fuel cell structure is by bipolar plates B and membrane electrode
MEA stacks together, and wherein the upper surface of bipolar plates is anode, and lower surface is negative electrode, and the upper surface of membrane electrode is negative electrode, membrane electrode
Lower surface be anode, the collection of battery pile overall current is realized by collector plate C1 and C2 at the two ends of battery pile.Wherein, film
Electrode is the place that electrochemical reaction occurs, and is made up of catalyst (generally Pt/C) and PEM.Wherein, in bipolar plates
Runner is carved with, to evenly distribute reacting gas.
In existing design, the general bipolar plates using graphite Carving Machining, as shown in Fig. 2 B1 is positive plate, B2 is the moon
Pole plate, B3 for positive plate runner for the circulation of fuel hydrogen, B4 for minus plate runner for oxidant gas (air or
Oxygen) circulation, B5 for minus plate opposite side runner for the circulation of coolant (deionized water).Fig. 3 is fuel cell membranes
Electrode sections structure.Wherein M1 is anode gas diffusion layer, and M2 is anode catalyst layer, and M3 is PEM, and M4 is negative electrode
Catalyst layer, M5 is cathode gas diffusion layer.Fig. 4 is existing fuel cell pile cross section structure, wherein, MEA is membrane electrode, B1
For positive plate, B2 is minus plate.
For the design and operation of existing fuel cell pack, the performance of fuel cell can only be by the overall voltage of battery pile
To judge or be judged by the voltage of each batteries in battery pile.However, when battery pile overall performance declines or a certain
During economize on electricity drops, cannot but judge a certain batteries of fuel cell occur in that failure at concrete which position, so as to cannot pin
Existing design is optimized and improvement.As shown in figure 5, the anode of the bipolar plates for the relatively conventional fuel cell of existing design
End front elevation, wherein dashed region are membrane electrode reaction zone, and obvious, hydrogen from hydrogen inlet to hydrogen outlet during Jing
Cross the reaction conditions such as the consumption transported with reaction of runner, concentration, humidity, the temperature of hydrogen is in whole membrane electrode conversion zone
Can not possibly be on all four；For air end there is also identical problem, during air is from air intlet to air outlet slit
Can not possibly be completely the same through transporting for runner；For cooling water there is also identical problem, cooling water from cooling water inlet to
Can not possibly be completely the same through transporting for runner during coolant outlet.Inconsistent local response condition and membrane electrode work
Make environment, cause membrane electrode in the performance of zones of different and the performance degradation skewness of zones of different, and limit fuel electricity
Pond performance and the regional area that the key in life-span is then that performance is minimum and performance degradation is most fast.
Fuel battery double plates front elevation (not showing runner) is illustrated in figure 6, dotted line membrane electrode conversion zone is drawn
The zones of different being divided into from R1 to R16, carries out qualitative analyses by taking the figure as an example, under conditions of fuel cell not wet operations,
The relative humidity of entrance R1 is minimum, and PEM of the relative humidity of exit R16 then at highest, therefore R1 is most dry
Dry, the internal resistance of cell is maximum, causes the performance in the region minimum, decays also rapid；Under high current density operating condition, by
In the increase for generating water, the relative humidity in R16 regions causes accumulation of the aqueous water in runner, so as to lead often beyond 100%
Cause gas to be delivered to the surface of reaction electrode, accelerate the performance degradation of membrane electrode.
The hydraulic performance decline and life time decay of fuel cell, typically previously occurs in (qualitative point as described above of some regional areas
Analysis, is not limited to above-mentioned analysis), and other most of regions then keep good performance and service life, however, these phenomenons
Cannot test under the conditions of existing fuel-cell device and quantitatively measure that (existing fuel cell can only measure battery in given current bar
Overall output voltage under part), so as to the reaction condition and performance of regional area cannot be improved by purposiveness, and significantly carry
High fuel battery performance and life-span.
Therefore, the how real reaction performance profile and reaction condition distribution of each regional area of real-time monitoring inside battery
Deng, so as to the purposive design for improving battery and operating parameter, optimize fuel battery performance and life-span, and greatly improve combustion
Material battery efficiency of research and development, becomes this area technical barrier urgently to be resolved hurrily.
