Compared with present techniques, this invention has such advantages as simple structure, high energy efficiency, safe operation and easy control.
Description
Technical Field
The invention relates to a device and a method for generating hydrogen, in particular to a hydrogen generating device and a hydrogen generating method which can provide fuel hydrogen for a fuel cell.
Background
A safe, reliable, and efficient hydrogen storage solution is very important for the commercialization of fuel cells. The demand of hydrides for mobile power sources is a very promising approach, and many methods are currently being developed to generate hydrogen by reacting hydrides with pure water, where NaBH is present4The reaction can be represented by the following chemical reaction formula: 。
other hydrides are: LiH, LiAlH4，LiBH4，NaH，NaAlH4，MgH2，KH，KBH4，CaH2，NaBH4。
These reactions are quite vigorous and require precise control to produce the required amount of hydrogen and to prevent explosions. One company in the United states uses NaBH4Solution of NaBH4The solution is contacted with a catalyst and the rate of hydrogen production is adjusted by adjusting the speed of the pump, which is very practical for high power fuel cells. However, for the battery with the power less than 20W, the reaction is violent and difficult to control, so that certain difficulty exists in practical application.
Some previous techniques have employed gas selective membranes to separate water from the hydride, permeating the water directly from the water side to the hydride side. Hydrogen is generated upon contact with water and hydrides due to the partial pressure of water, however, the porous membrane is permeable to both water and hydrogen, and thus the reactants need to be sealed to prevent hydrogen leakage. And the water for reaction must be packed in the hydrogen generator during the production process, thus reducing energy efficiency during transportation.
One U.S. patent describes a system that consists of two parts, one part being a chemical hydride and the other part being an aqueous solution of methanol. The methanol water solution can diffuse to the hydride side through the separation membrane to react with the hydride to generate hydrogen. A hydrogen outlet is mounted on the reaction vessel, however, a good seal must be provided to cope with the toxicity and high diffusivity of methanol.
Another us patent describes a hydrogen generating apparatus that uses a water selective membrane to separate water and hydride. Such a film does not allow H2、N2The gas is passed through, which facilitates hydrogen collection. Unfortunately, this system has considerable drawbacks in practical use, firstly because there is no catalyst or acidic substance inside, water and NaBH4The chemical reaction between becomes rather slow and insufficient to supply the need; secondly, the reaction process is carried out when water selectively passes through the membraneContact with liquid water makes the counterstrain difficult to control, since a large amount of water passes through the membrane directly to the hydride side.

Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments.
The hydrogen generator with high energy density adopts various factors and technical schemes, and aims to improve the energy efficiency, and the purpose is realized by reducing the carrying amount of water; another object is to obtain sufficient hydrogen through the hydride and a controllable rate of hydrogen generation.
Dry powdered hydrides like LiH, LiAlH4，LiBH4，NaH，NaAlH4，MgH2，KH，KBH4，CaH2，NaBH4All have very high energy density, NaBH4The hydride is preferably a solid NaBH due to its high energy density and the absence of harmful species formed after the reaction4Can absorb water vapor from the environment to react, especially in the environment with high humidity. If no catalyst is present like CoCL2Ni, Pt or in an acidic environment, this reaction is so slow that in most cases it is not sufficient to supply a fuel cell. Through experiments, we can see that in NaBH4Addition of catalysts such as CoCL to the reaction with water2After that, the reaction speed is obviously accelerated. We therefore select CoCL2Due to its low price and highly efficient catalytic properties.
The mixture is preferably dry powderIn order to increase the contact area for the reaction. The powderis prepared by mixing CoCL2Dissolving in isopropanol, then NaBH4The powder is put into solution. NaBH4Commercially available from companies such as Morton, Eagle-Picher or Bayer. These materials can be dried under vacuum at a temperature of 60 ℃.
These NaBH4And CoCL2The mixture may be placed in a fuel container having at least one water vapor selective membrane that maximally allows water vapor to enter the chemical from the water source side, hydrogen gas being generated in the container and exiting through an outlet connected to the container and having a filter mounted thereon. NaBH4The reaction product of sodium metaborate with water occurs in NaBH4A layer of hard shell is formed on the surface of the particle, and meanwhile, the volume of chemical substances in the container is increased during reaction, so that the container cannot be completely filled with reactants, a space of 5-80% is reserved, and the water vapor can be favorably and fully contacted with NaBH4And CoCL2And hydrogen gas.
The water-gas selective permeable membrane is composed of at least two layers, wherein one layer is a water-selective permeable material and the other layer is a gas-selective permeable material, the water-selective permeable material is preferably a Nafion membrane of DuPont, a Cellulose membrane can also be used, and the gas-selective material is preferably a porous PTFE membrane. As shown in fig. 1: in the figure, 1 is a hydrogen gas outlet, and the hydrogen gas outlet can be connected with a gas storage device or a power generation device through a pipe. Represented by NaBH 4 in the figure4In admixture with a catalyst, 5 being a container which is protected against reception by NaBH4The space reserved for the mixture formed by the catalyst to absorb water vapor to expand is 6 to prevent NaBH4The filter which is used for filtering when waste residue or blocky substances and the like generated in the reaction process of the mixture and the catalyst flow into or block the air outlet and the like is made of NaBH4The mixture with the catalyst absorbs the water vapor in the surrounding environment, and the water vapor enters the NaBH through a water selective permeable membrane 2 and an air selective permeable membrane 3 shown in the figure4Reacting with the substance fuel container composed of catalyst to generate hydrogenThe outlet of 1 flows into the fuel cell or hydrogen storage vessel.
We have observed in experiments that if we contact the Nafion membrane directly with water, the amount of water diffusion is very large and the NaBH in the vessel is very large4And water, and thus the chemical reaction becomes relatively violent and uncontrollable, so that the reaction is controlled by avoiding direct contact between the Nafion membrane and liquid water, and therefore a gas selective material is required to be placed outside the Nafion membrane, and a porous PTFE membrane is preferred, while another advantage is that the diffusion rate of water can be adjusted by adjusting the thickness and pore size of the PTFE membrane. When the container is placed in an environment with high humidity, the diffusion degree of water vapor can be adjusted to control the generation rate of hydrogen, and the gas selective permeation material can filter low-purity water, so that the container is very useful in the situation that outdoor pure water is not easy to find.
A gas selective permeable membrane can be added on the inner side of the water selective permeable membrane, just like a sandwich, so as to avoid the reaction product from forming a hard shell on the surface of the water selective permeable membrane.
The source of water for the moisture may be liquid water added to the exterior of the container or water from the ambient atmosphere, and a porous hydrophilic material may be placed on the exterior of the fuel container to hold the liquid water and provide water through intimate contact with the container. This has the advantage that the water for the reaction does not have to be stored in the hydrogen generator beforehand, so that the weight and volume are greatly reduced during transport; secondly, the water needed by the hydrogen generator is far less than that of NaBH4Solution is used as reactant for hydrogen generator. The former classical use of NaBH4Solution hydrogen generators carrying only about 20% to 30% NaBH by weight of the reactants4Our preferred objective is to use NaBH4Reaching more than 50 percent of the weight of reactants. At the same time, water in the surrounding environment can also be utilized, with an energy density 5 times that of hydrogen generators in solution. If ambient water is used as the water source, the fuel container surface may initially be in direct contact with a minimal amount of liquid water to rapidly produce the desired amount of liquid waterHydrogen gas.
The hydrogen gas generated from the hydrogen-generating apparatus is supplied to a fuel cell or collected in a hydrogen storage container, and high purity hydrogen gas can be obtained through a multi-layer filtering apparatus, and porous PTFE can be preferable.
The fuel container needs to be sealed airtight during storage, so that no moisture can enter the container, and once the fuel container is sealed, no moisture enters the container, the reaction stops.
