Abstract
A movable hydrogen generating device relates to methods and devices for gas generating when liquid is contacted with solid, in particular to a hydrogen generating device by means of catalysis and hydrolysis of hydroboron solution and combination of the device with fuel cells. The device utilizes the water absorption characteristic of a sponge body. Reaction liquid which is stored inside the sponge body is contacted with a catalyst inside the sponge body and hydrolysis occurs. Generated hydrogen spreads out of the sponge body through pore paths and leads to the fuel cells through a hydrogen outlet valve. From beginning to end, no free-flowing liquid exists inside the device, and the fact that gas-liquid separation is not limited by orientation of the device is realized. The device consists of a tank body, a cover body and the sponge body which is made of porous water absorption materials. The catalyst is carried inside the sponge body. The reaction liquid is injected into the sponge body through a reaction liquid inlet on the top of the cover body, the reaction liquid is contacted with the catalyst to generate hydrogen, and the hydrogen leads to the fuel cells through the hydrogen outlet valve. The device is simple in structure, can be inclined or placed upside down randomly during hydrogen generation, and is good in movability.

Mainly concentrate on the catalyst performance to hydroborate solution catalyzing hydrolytic hydrogen production Study on Technology both at home and abroad at present, numerous catalyzer such as ruthenium, rhodium, platinum, nickel, cobalt, iron all have catalytic activity preferably to borohydride hydrolytic, the catalyzer that repeatedly recycles is selected ruthenium, rhodium, platinum etc. usually for use, and cheap nickel, cobalt, iron etc. are then selected in disposable use.Cast aside cost factor, one of current restriction borohydride hydrolytic hydrogen production and biggest obstacle of using with this technology of fuel cell coupling thereof are exactly the development of its device for producing hydrogen.
Chinese patent (publication number CN 101049907A) and Chinese patent (publication number CN 201381220Y) have been announced two kinds of hydrogen production process and device, the two all utilizes the variation of liquid level of solution pressure reduction to impel flow of solution, regulator solution contacts with catalyzer, reaches the purpose of control hydrogen manufacturing.More than two kinds of device for producing hydrogen all adopted the principle of its general producer, therefore, the placement orientation of device all was restricted when hydrogen took place, the device angle of inclination was less when hydrogen took place, and more can not be inverted, and was only applicable to use occasions such as fixed installation.The utility model then is a water absorption character of utilizing the foam sponge body, and reaction solution and product solution are attracted deposits all the time in the vesicular structure of cavernous body, is in first valve state, therefore, device was not placed the restriction in orientation when hydrogen took place, and can tilt arbitrarily or be inverted, and had good travelling performance.
Summary of the invention
The purpose of this utility model provides a kind of method and device of simple in structure, hydroborate solution catalyzing hydrolytic hydrogen production that travelling performance is strong.
For achieving the above object, the structure of this device is design like this: device comprises tank body 1, lid 2 and cavernous body 3 three parts; Catalyzer 4 is supported in the vesicular structure of cavernous body 3; Have gim peg 5 on tank body 1 inwall, be used for fixing cavernous body 3; Hydrogen outlet valve 6 and reaction solution inlet 7 is arranged on the lid 2; Hydrogen outlet valve 6 links to each other with the hydrogen inlet of fuel cell, the supply external demand; The top of reaction solution inlet 7 is connected on the lid 2, and the bottom is inserted in the cavernous body 3.
In said apparatus: cavernous body 3 is the porousness water-absorbing material, and catalyzer 4 is supported in the vesicular structure of cavernous body 3, and repeatedly use capable of circulation also can be changed as required after simple the cleaning.
This device is a water absorption character of utilizing foam sponge body 3, the reaction solution that injects is attracted deposits in cavernous body 3 inside, the catalyzer 4 that supports in reaction solution and the cavernous body 3 contacts, the hydrolysis releasing hydrogen gas takes place, the hydrogen that generates diffuses out cavernous body 3 rapidly by the duct, leads to fuel cell through hydrogen outlet valve 6.Because reaction solution and product solution are attracted deposits all the time in the vesicular structure of water-absorbent cavernous body 3, are in first valve state, thereby broken away from the restriction that device is placed the orientation separating between the hydrogen that makes generation and the reaction solution.
The utility model hydrogen method for generation operation steps is as follows: the cavernous body 3 that will support catalyzer 4 is in advance put into tank body 1, by gim peg 5 that cavernous body 3 is fixing, cover lid 2, the bottom of reaction solution inlet 7 is inserted in the cavernous body 3, hydrogen outlet valve 6 external fuel cells, the reaction solution 7 external liquid-supplying systems that enter the mouth; When needing hydrogen, by reaction solution inlet 7 reaction solution is injected in the cavernous body 3, reaction solution contact with catalyzer 4 on the cavernous body 3, and hydrogen takes place, hydrogen after the duct diffuses out cavernous body 3, again by hydrogen outlet valve 6 towards fuel cell, supply external demand; Off-response liquid inlet 7, the reaction solution stop supplies, hydrogen stops.
Catalyzer 4 in the utility model cavernous body 3 is excessive, the all hydrolysis rapidly of the feasible reaction solution that injects, by the injection rate of control reaction solution and the generation that speed is controlled hydrogen, the cavernous body 3 that is supporting catalyzer 4 can circulate after simple the cleaning and repeatedly use.
This apparatus structure is simple, because inner the no free flowable liquid of device, so the generation of hydrogen and derivation be not subjected to device to put the restriction in orientation, and device can tilt arbitrarily or be inverted, and has good travelling performance.
