Description

A kind of major diameter hydrogen bearing alloy jar and preparation method thereof
Technical field
The invention belongs to the hydrogen storage technology in Hydrogen Energy field, particularly a kind of fuel cell power source hydrogen bearing alloy jar and preparation method thereof.
Background technique
Hydrogen Energy has cleaning, efficient height, plurality of advantages such as renewable, is a kind of novel energy that is subjected to whole world common concern.Typical case's representative that hydrogen fuel cell is used as Hydrogen Energy, plurality of advantages such as have that charging time is long, efficient, environmental protection, volume are little, in light weight shows good prospects for application in fields such as communications and transportation, distributed power generation and standby power supplies.
Fuel cell power generation needs a large amount of hydrogen fuels.At present, the practical hydrogen storage and the mode of conveying mainly contain three kinds, i.e. high-pressure bottle (being mainly steel cylinder), liquid hydrogen storage tank (cryogenic Dewar bottle) and hydrogen bearing alloy jar.The hydrogen bearing alloy jar is to utilize the chemical reaction of hydrogen and alloy to come storage of hydrogen, is a kind of solid-state hydrogen storage technology, compares with other modes, has low, the characteristics such as density is high, hydrogen supply purity height of storage hydrogen pressure, is particularly suitable for doing the hydrogen fuel cell hydrogen source.
It is a chemical reaction process that hydrogen is put in the hydrogen bearing alloy suction, is attended by huge thermal effect, and heat release when it inhales hydrogen is then absorbed heat when putting hydrogen.Simultaneously, hydrogen bearing alloy is inhaled and to be put the hydrogen process and will produce volumetric expansion or contraction about 20%, make hydrogen storing alloy powder put in the hydrogen cyclic process efflorescence takes place, easily harden and phenomenon such as stress raisers, thereby cause hydrogen bearing alloy jar decreased performance or inefficacy in suction.Therefore, the design of hydrogen bearing alloy jar and make and to consider simultaneously to conduct heat and the requirement of mass transfer.Along with the development of solid-state hydrogen storage technology, scientific and technical personnel have delivered some patented technologies about the hydrogen bearing alloy jar successively both at home and abroad, but all have certain shortcoming and defect.For minor diameter hydrogen bearing alloy jar, ZL200310101758.6 is by being provided with a certain amount of fin at the hydrogen bearing alloy tank wall, storage hydrogen device and environment exchange area have been increased greatly, significantly improved the heat-exchange performance of storage hydrogen device, but it is relatively large that this structure takies volume, and limited to the effect of major diameter hydrogen bearing alloy jar; For major diameter high capacity hydrogen storage alloy tank, its uniformity and coherence request to hydrogen bearing alloy bed body heat transferring, mass transfer and alloy filling is very high.Because the temperature conductivity of hydrogen-bearing alloy powder is very poor, almost work as with glassy phase, the radial thickness of major diameter hydrogen bearing alloy jar is bigger, only depend on the transmission of heat of alloy powder obviously to be difficult to satisfy the heat demand that big flow is put hydrogen continuously, must improve heat exchange efficiency at the heat exchanging tube that hydrogen bearing alloy bed body is provided with certain-length.Simultaneously, existing hydrogen bearing alloy jar directly is filled in hydrogen storing alloy powder in the hydrogen storing tank mostly, and by craft or mechanical vibration jolt ramming, the filling uniformity of alloy powder in jar is difficult to assurance, and along with alloy powder is put efflorescence in the hydrogen process in suction, fine powder is progressively assembled, generation is hardened and stress raisers, hydrogen bearing alloy jar mass-transfer performance is descended, and local differential deformation easily takes place, reduce the working life of hydrogen bearing alloy, even serious accident such as take place that tank body lost efficacy, breaks.ZL200320126461.0 discloses a kind of structure that has internally spiral heat-exchanging tube, though improved the heat exchange efficiency of hydrogen bearing alloy jar, but because the heat transfer that directly makes progress of bed body is still mainly by the transmission of heat of hydrogen storing alloy powder, heat exchange efficiency is difficult to satisfy the continuous operation of multikilowatt fuel cell to big flow, stablize the requirement of hydrogen supply for a long time.With it simultaneously, spiral heat exchange tube makes the tank interior complex structure, and hydrogen storing alloy powder is difficult to even filling, phenomenon such as easily harden and stress is concentrated, and its Security and reliability will significantly reduce.
