Description
Technical field:
The present invention relates to a kind of fuel cells using novel installation case.
Background technique:
Fuel cell is a kind of the chemical energy being stored in fuel to be converted into electric energy by electrochemical reaction
Power generator, we often claim " pile " or " galvanic pile module " device chemically reacted, as long as in anode-side and cathode side
Continuous supply fuel (generally hydrogen) and oxidant (generally air), it can be by redox reaction, constantly
Ground externally exports electric energy.Unlike general rechargeable battery (such as lithium battery), simple a fuel cell or fuel
Battery stack unit be it is inoperable, it needs the auxiliary system of a set of complexity to cooperate with it, constitutes fuel cell hair
Electric system could externally generate electricity.One typical fuel cell generation generally further includes other than fuel cell pile
Hydrogen supply Proton Exchange Membrane Fuel Cells is a kind of the chemical energy being stored in fuel can directly to be turned by electrochemical reaction
As long as the power generator for turning to electric energy constantly supplies fuel (generally hydrogen) and oxidant (one in anode-side and cathode side
As be air), it can by redox reaction, constantly externally output electric energy.With general rechargeable battery (such as lithium
Battery) unlike, simple a fuel cell or fuel cell pile unit are inoperable, its a set of complexity of needs
Auxiliary system cooperate with it, constituting a fuel cell generation could externally generate electricity.One typical fuel cell hair
Electric system, other than fuel cell pile, generally further include hydrogen air-channel system, cooling circuit system and empty air-channel system and
Fulgurite reason and control subsystem etc..
Fuel cell is a kind of power supply energy source device, and structure is complicated for the burst mode of fuel cell at present, fuel electricity
Pond includes installs case and the galvanic pile module, fuel cell controller, hydrogen gas circulating pump, the hydrogen inlet valve door part that are mounted in installs case
Deng a small amount of hydrogen can be revealed in use since fuel cell uses hydrogen or other fuel gas as energy source raw material
Gas or fuel gas, if the hydrogen or fuel gas of accumulation excessive concentrations probably generate the danger of explosion inside cabinet,
Fuel cell has a very important safety measure in use thus, is the hydrogen of the leakage to fuel battery inside
Or the discharge of fuel gas continuous and effective, so that combustable gas concentration in air is lower than explosion ratio value or License Value, and
Real-time monitoring is carried out to the concentration of its fuel gas.The wind exhausting outlet of the existing fuel cell articles in market, is arranged at cabinet
Side, there are unreasonable places for the structure: fuel gas is lighter than air, and after leakage, fuel gas can up escape, and air draft
It is not the highest place of fuel cell that the side of box-frame, which is arranged in, in mouth, just will appear accumulation fuel gas not in highest place
It can effectively be discharged, therefore can have security risk.
In addition the installs case of fuel cell mostly uses following two structure composition: first is that adding lid group by semi-enclosed cabinet
At, cabinet includes bottom surface and several sides, and cabinet is made of die-casting process, but the weight weight and processing cost of this outer container are high,
All there is the shortcomings that low packaging efficiency, poor universality in this installs case, cause battery system to assemble groups of inefficiency, to combustion
Expect that the popularization and application of battery product batch on the market are very unfavorable；Second is that being made of frame structure, frame structure frame structure
Sheet metal process is made, and the processing technology of this installs case is complicated and is not able to satisfy the sealing protection grade of IP67.
Summary of the invention:
It is an object of the present invention to provide a kind of fuel cells using novel installation case, solve air draft in the prior art
