Description
Technical field
The utility model is related to fuel cell pile encapsulation fields more particularly to a kind of fuel cell pile low temperature cold to open
Dynamic package casing.
Background technology
Fuel cell is a kind of the chemical energy being stored in hydrogen fuel and oxidant (oxygen) to be converted into electric energy
Device；Basic principle is that oxidation occurs respectively for hydrogen and oxygen (air) and reduction reaction generates water, generates thermal energy and electric energy；Tool
There are the startup of energy conversion efficiency high and low temperature, environmental-friendly, low noise, safe and reliable, specific power and specific energy density height etc. to protrude
Advantage；It all has a good application prospect in mobile power, stationary electric power plant and traffic and transport field, is considered most potential
Environmental pollution, one of the effective means of energy crisis are solved, the emphasis of domestic and international government, vehicle enterprise and scientific worker is subject to close
Note.
Fuel cell is increasingly extensive to be applied to the multiple fields such as automobile, power station.In order to widen its actual application value, fuel
The working environment of battery is often more severe, such as low temperature, have shower water, need it is dust-proof.Therefore, it is the core of protection fuel cell
Partly (fuel cell pile) generally requires to be encapsulated in a manner that semitight is even hermetically sealed.
Fuel cell pile is usually formed by multiple cells in series, and monocell includes membrane electrode, bipolar plates and sealing element.
By the way of generally being radiated using water-cooling and air, often outside a small amount of water penetration to pile and volatilize.Simultaneously in single-unit
Due to concentration difference, vapor is easy to diffuse out from the partition in two sections vapor caused by cathode side.
The ambient temperature of pile is generally relatively low, and the vapor diffused out is accumulated in the encapsulation of fuel cell pile,
Therefore, vapor, which is easy to moisture condensation, becomes liquid water；And the thickness of pile single-unit is smaller (often only have 1-2mm), if having water into
Enter and short circuit is then inevitably resulted on the side stacked to single-unit, therefore the liquid dew condensation water inside pile encapsulation is pile safety
Larger hidden danger.
In addition, it is sealed between the monocell of fuel cell pile usually using tree lace.In practical applications, by pile component
The gas barrier properties of level of processing, assembling force attenuation and sealing material itself influence, and put to that can not ensure to be fully sealed, especially
It can not ensure being fully sealed for fuel gas hydrogen.Therefore, fuel cell is when automobile-used, between pile body and pile encapsulation
There are the accumulation of pile leakage hydrogen in space.If density of hydrogen meets or exceeds 4%, there are explosion danger, serious threat
Personal safety.Therefore, it is necessary to the hydrogen of pile leakage is handled.It can slow down pile under certain conditions using ventilation
Interior leakage hydrogen and the amount of liquid water, and when compared with low ambient temperature, it, can if the gas temperature encapsulated into pile is very low
Cause vapor direct liquefaction and accumulate on pile encapsulation interior plate, therefore liquid water threat can not be solved at all.If in ring
Border temperature is less than zero degree, such as at -20 DEG C, and the vapor in pile encapsulation can sublimate when running into package board immediately as frost, and tire out
Product.With fuel battery temperature rise or environment temperature rise, the frosting on the inside of package board, which can be melted, becomes liquid water danger
And pile safety.
The utility model patent of Patent No. 99219220.X mentions existing two kinds of fuel cell press-fit approach, i.e., built-in
Bolt press-fit approach and external bolt press-fit approach, both press-fit approach there are it is apparent the defects of, such as it is interior wear bolt press fitting by
Reduce effective electrochemical area of material in that need to be punched on deflector, carbon paper and film, drop the volumetric specific power of battery
It is low, and the press fitting of external bolt easily causes monocell to be subjected to displacement in the vertical direction of press mounting bolt.It is fired for above two
Material battery press-fit approach shortcoming devises a kind of shell of overall package, adds the stability of structure, can be in various vibrations, punching
It hits under environment and works, but do not account for the water proof and dust proof of package casing and electrical isolation design.
Although the patent of invention of the patent No. 201010153563.6 has reached " water proof and dust proof of integrated design, antidetonation, absolutely
All particular requirements such as edge, heat-insulated, hydrogen leak protection ", but parts are more, heavier-weight, installation step is also more numerous
Trivial, pile has encapsulated, and volume is also bigger than normal.
Beautiful, simple and water proof and dust proof, the prevention of encapsulation are all only considered for existing fuel cell packaging shell structure
The conventional funcs such as leakage, for the heat insulation function of outdoor low temperature environment designing fuel cell, be not suitable for outdoor base station and
The standby power systems such as automobile.
