Abstract
This invention relates to apparatus and method for generating H2. Generation of H2 in this invention is realized by contact reaction between water vapor and a dry mixture of hydride and catalyst. The dry mixture is stored in a fuel container selectively permeable for water vapor, and the permeation rate of water vapor from the water source is adjustable. The fuel container is selectively permeable for water vapor, while liquid-state water, H2, O2, N2 and CO2 are impermeable. After generated in the fuel container, H2 is collected and filtered, and then transported through a gas exit on the fuel container to fuel cells or H2-storage containers. Compared with present techniques, this invention has such advantages as simple structure, high energy efficiency, safe operation and easy control.

2After, speed of response is obviously accelerated.Why we select C
OCL
2Be because its low price and catalysis characteristics efficiently.
The first-selected exsiccant powder of mixture is the contact area for augmenting response.The making method of powder is at first with C
OCL

2Mixture can put into a fuel container that has one deck aqueous vapor selective membrane at least, and this film allows aqueous vapor to enter into the chemical substance side from the water source side to the full extent, hydrogen promptly produces in container, and discharges from being connected the outlet that container is equipped with strainer.NaBH
4With the reaction product sodium metaborate of water can be at NaBH
4Particle surface forms one deck duricrust, and simultaneously, the volume of chemical substance can increase in reaction in the container, so can not fill up reactant fully in the container, must reserve 5%～80% space, also helps to make aqueous vapor fully contact NaBH
4And C
OCL
2Mixture and the discharging of hydrogen.
The aqueous vapor permselective membrane is made up of two-layer at least, one deck is the material of water selective permeation and the material of one deck gas selective permeation, the Nafion film of our first-selected E.I.Du Pont Company of water selectivity permeable material, the Cellulose film also can use, the first-selected porous PTFE film of gas selective material.As shown in Figure 1: 1 is the production well of hydrogen among the figure, and production well can outwards connect accumulator unit or power generation assembly by pipe.Among the figure 4 the expression by NaBH
4With the mixture of catalyzer composition, the 5th, container receives by NaBH for preventing
4The mixture of forming with catalyzer absorbs that aqueous vapor expands and the space reserved, and the 6th, prevent by NaBH
4The mixture of forming with catalyzer produces inflow such as waste residue or cake mass or blocks the strainer of filtrations such as air outlet in reaction process, by NaBH
4The mixture of forming with catalyzer absorbs the aqueous vapor in the surrounding environment, and the water permselective membrane 2 gentle permselective membranes 3 by representing among the figure enter aqueous vapor NaBH is housed
4React in the material fuel container of forming with catalyzer, the hydrogen that reaction produces, 1 outlet flows among fuel cell or the hydrogen storage vessel from figure.
We observe in experiment, if we directly contact the Nafion film with water, the diffusing capacity of water is very big, the NaBH in the container
4Can form solution with water, what chemical reaction will become like this is quite violent and uncontrollable, therefore will avoid the Nafion film directly to contact and control reaction with liquid water, so just need outside the Nafion film, put one deck gas selective material, porous PTFE film is first-selected, and another benefit be can be by adjusting the PTFE film thickness and the aperture diffusivity of adjusting aqueous vapor.When container is placed in the bigger environment of humidity, control the generation speed of hydrogen with regard to the diffusibleness that helps adjusting aqueous vapor, also having a benefit is exactly this gas selective permeation material, can filter the water of low-purity, very useful under this situation that pure water is difficult for seeking out of doors.
In the inboard of water permselective membrane, we can add one deck gas selective permeation film again, as sandwich, form one deck duricrust to avoid resultant of reaction on water permselective membrane surface.
The water source of aqueous vapor can be to be added in outer liquid water of container or the water in the ambient atmosphere environment, and the outside that the porous water wetted material can be placed on fuel container fixes liquid water, by supplying with moisture with tight contact of container.The benefit of doing like this is at first to react water not need to exist in advance in the hydrogen generator, and weight and volume can significantly reduce when transporting like this; Next is the needed water of this hydrogen generator, much smaller than adopting NaBH
4Solution is done the needed water of hydrogen generator of reactant.Use NaBH with previous classics
4The hydrogen generator of solution can only carry about NaBH of 20% to 30% of its reactant weight
4, and the purpose of our first-selection is to make NaBH
4Reach more than 50% of reactant weight.Simultaneously, the water in the surrounding environment also can be utilized, and 5 times of energy densities are to the hydrogen generator that adopts the solution form.If as the water source, the fuel container surface just can contact by direct with indivisible liquid water in the time of at the beginning with the water of surrounding environment, make the hydrogen of its rapid generation aequum.
The hydrogen fueling battery that produces from hydrogen production bioreactor or be collected in the hydrogen storage vessel can obtain highly purified hydrogen through the bed filtration device, and porous PTFE can be preferred.
Fuel container need seal when storing and make it airtight, does not so just have aqueous vapor to enter in the container, in case do not have aqueous vapor to enter in the container after the sealing, reaction will stop.
