Description
Technical field
The invention belongs to field of fuel cell technology, more particularly to a kind of spiral-flow type gas-liquid for sodium borohydride hydrogen manufacturing
Separator.
Background technology
At present, Proton Exchange Membrane Fuel Cells (PEMFC) light weight, heat supply reliability of powering, shockproof, noise is small, and energy
Production drinking water, all these advantages are that other energy are incomparable.And how to store to high-density and quickly obtain pure
Net hydrogen is a bottleneck of PEMFC technology popularization and applications.Current hydrogen gas storage method is mainly physics high-pressure hydrogen storing and chemistry
Hydrogen storage.High-pressure cylinder hydrogen storage, even if at a very high pressure, hydrogen 2% of quality less than mass of system in itself.Gas cylinder quality
Problem and gas leakage problem are also very important safety problem.Chemical hydrogen storage mainly has hydride hydrogen-storing and hydroboration
Thing hydrogen storage two ways.Metal hydride could be used in must being mounted in the container of compression resistance, therefore hydrogen-storage density is also than relatively low,
About 0.65%.And high-purity hydrogen must be filled after being finished every time, being flushed with hydrogen under the conditions of irresistible natural disaster and man-made calamity is
It is unpractical.Sodium borohydride hydrogen-feeding system is then entirely different, as long as storing a certain amount of sodium borohydride as guarantee fuel, so that it may
With continuously long-term power supply.And sodium borohydride hydrogen-storage density is high, itself hydrogen content reaches 10.6%, about conventional metal hydride
5 times.Sodium borohydride is relatively stablized in atmosphere, is dissolved in water and forms liquid hydrogen storage material, does not have spontaneous combustion, the danger of blast.Pass through
Catalytic hydrolysis reaction sodium borohydride can rapidly release whole hydrogen under normal temperature and low temperature, and the startup time is short, minimum hydrogen discharging temperature
Reachable -40 DEG C.Compared with the modification of traditional chemical hydride (methane, methyl alcohol etc.), sodium borohydride produces hydrogen flow simply, system
Simply, hydrogen speed is produced adjustable, can be using handling fuel cassette or the method for changing solution, when substantially prolongs the work of fuel cell
Between.In the wild, it is possible to use the water source such as seawater, river, stream, snow-broth produces the raw material of hydrogen as sodium borohydride hydrolysis, extreme
In the case of it is even possible that with urine as water source.So sodium borohydride is a kind of ring for being particularly suitable for field, extreme
It is the preferable hydrogen storage media of fuel cell hydrogen-feeding under border.
Using NaBH4Aqueous slkali next life hydrogen producing, it is necessary to have sufficiently fast reaction speed.In order to accelerate reaction, use
Catalyst is method most simple and easy to apply.In sodium borohydride hydrogen-feeding system, the catalyst that preparing hydrogen by sodium borohydride hydrolysis is used
It is broadly divided into two classes：Fixed bed catalyst and acid catalyst.In fixed bed catalyst, the catalyst being most widely used is attachment
Noble metal catalyst on porous carrier materials.Millennium Cell Inc. of U.S. Amendola etc. is loaded to spent ion exchange resin
Ru catalyst carried out systematic research, and the catalyst is applied in the instant hydrogen supply device of the said firm.By various
Expression activitiy after carried ion exchange resin 5%Ru, finds using anion exchange resin than cationic ion-exchange resin effect
More preferably.And research and development centre of Japanese Toyota uses supercritical process by Fe, Ni, Pd, Ru, Rh, Pt even load in TiO2On as boron
Sodium hydride hydrolytic hydrogen production catalyst.
Although from the point of view of reaction equation, hydrogen is the unique gas produced by sodium borohydride hydrolysis.But in real reaction
In, because reaction speed is very fast and very big fuel factor, solution in the contact position temperature with catalyst up to 60~80 DEG C, even more
It is high.Hydrogen carries the misty liquid droplets of a large amount of vapor and solution during being escaped from solution.The solution for having 5%~10% exists
Carried away by hydrogen in course of reaction.If hydrogen is supplied to Proton Exchange Membrane Fuel Cells, although moisture therein is combustion
Required for material battery, but the Na for wherein containing+、OH-、BH4 -And B (OH)4 -The performance of PEMFC will be produced Deng alkali ion
Raw influence.In simple terms, sodium borohydride solution carries stronger alkalescence, therefore institute's hydrogen producing is in due to having carried substantial amounts of drop secretly
Stronger alkalescence.And PEMFC is sour environment, performance and the life-span of PEMFC can be had a strong impact on using such hydrogen.Therefore must
The misty liquid droplets in sodium borohydride hydrolysis institute aerogenesis body must be removed, good gas-liquid separation is carried out, to eliminate impurity to combustion
Expect the influence of battery.Common liquid NaBH4Device for preparing hydrogen through hydrolysis all has 2 Primary containers, 1 fuel tank and 1 raffinate
Tank, NaBH4As fuel storage in fuel tank, during work, fuel enters reactor to the aqueous solution, and NaBH4 occurs hydrolysis hair and answers,
Generation hydrogen and NaBO2, NaBO2It is dissolved in the water.Product and unreacted fuel formation gas-liquid mixture are directly entered residual
Flow container, by after gas-liquid separation, hydrogen leaves residual liquid tank, for fuel cell pack.Hydrocyclone due to its efficiency high,
Treating capacity is big, the low advantage of maintenance cost, is widely used to the every field such as colliery, chemical industry, food processing and the energy, industry
In the hydrocyclone commonly used be structurally characterized in that diameter is small and tapered segment is long.The hydrogen generating system application ratio of this double cavity structure
It is wide.
The hydrogen generating system of this structure, there are the following problems：First, due to being provided with bed room catalyst chamber, structure is not tight enough
Gather, it is difficult to minimize；Second, the pipe resistance of solution catalyzing room can increase the pressure loss of solution, increase energy consumption；3rd, adopt
During with fixed bed catalyst such as fixed-bed Raney nickel etc. as preparing hydrogen by sodium borohydride hydrolysis catalyst, the concentration of sodium borohydride solution
Can not be too high, can otherwise cause that face separates out the kodalk generated in course of reaction on a catalyst, covers active sites so that urge
Agent is gradually inactivated, this severely limits the concentration raising of sodium borohydride, so that the hydrogen storage rate of whole system declines.
