Description
Technical field
The present invention provides a kind of fuel cell pile, belongs to field of fuel cell technology.
Background technique
Proton Exchange Membrane Fuel Cells (proton exchange membrane fuel cell, PEMFC) is a kind of clear
The electrochemical generating unit of clean environmental protection, since its is small in size, light weight, operating condition is mild, energy conversion rate is high, structure is simple
And the response advantages such as rapidly, can be widely applied to the vehicles, stationary power generation, material carry, backup power source and portable
All various aspects such as power supply.Hydrogen Energy provides a new approach with fuel cell technology for the utilization of clean energy resource system.Hydrogen
It is from a wealth of sources, both include renewable energy, also includes non-renewable energy resources resource.Hydrogen Energy can become the energy complementary with electric power
Carrier, so that the carbon emission of current energy resource system be effectively reduced.Therefore, PEMFC be considered as 21 century first choice cleaning, efficiently
Power generator.
For vehicle fuel battery engine, the service life must reach with the comparable level of conventional engines, be possible to
Realize industrialization.The plan of U.S. Department of Energy Hydrogen Energy, Japanese new energy and industrial technology develop the committee and European Hydrogen Energy and fuel
Battery technology forum thinks, for vehicle fuel battery engine service life at least 5000h(passenger car) and 10000h(commercialization
Vehicle) just with the possibility of industrialization.Compared to static application environment (such as power station or mobile power source), vehicle environment and work item
Part seems more severe, the durability of PEMFC engine and contemplates that a certain distance at present.Wherein, the service life of pemfc stack
One of an important factor for being the durability of influence PEMFC engine.
Traditional pile is to be pressed pressing molding after membrane electrode, the superposition of bipolar plates interval by adjusting in the process
Power or pile total length control the total compression amounts of gas diffusion layers, due to the pretightning force distribution in compaction process, inside pile
Unevenly, cause the decrement of the gas diffusion layers of each monocell in pile not of uniform size, i.e., the gas of part monocell expands
Dissipate layer decrement gas diffusion layers bigger than normal, part monocell decrement it is less than normal, then pile in the process of running, especially
After long-play, the performance gap between each monocell becomes increasing, generates " short -board effect ", influences pile
Service life.
For traditional pile, when pile performing leak test is unqualified or pile breaks down in the process of running, very
Heapcheck may be torn open, due to repeated disassembled and assembled pile, gas diffusion layers are repeatedly extruded, cause the structure of gas diffusion layers by
Irreversible damage hinders the transmission of reaction gas and water, to influence the service life of pile.
In addition, the sealing performance of pile is also to influence one of the key factor in pile service life, the gas of traditional pile is close
Envelope is compressed by using five in one as anode plate/anode-side gasket/membrane electrode frame/cathode side gasket/cathode plate
Structure realizes that this is higher to anode-side gasket and the required precision of the height of cathode side gasket, and this structure
Dislocation between pole plate easily occurs in the environment of vibration and impact for pile, is easy for that leakage problem can be generated in this way, leads to electricity
Heap cannot be run, and influence the service life of pile.
Therefore, it is badly in need of finding a kind of novel pile, can accurately controls the pressure of the gas diffusion layers per a piece of membrane electrode
Contracting amount, and be avoided that since the gas diffusion layers that disassembly pile causes when pile sealing problem or pile break down are by repeatedly
Irreversible damage caused by squeezing, moreover it is possible to reduce the requirement to gas side gasket, improve the service life of pile.
