The examples are given only for illustrating the present invention and are not intended to limit the scope of the present invention. Any obvious modifications or variations can be made without departing from the spirit or scope of the present invention.
Overview of Hydrogen Release from Hydrogen storage alloys
The hydrogen bottle reacts under specific temperature and pressure to dissociate the metal hydride, release hydrogen atoms, which diffuse to the alloy surface to recombine into hydrogen molecules, and release hydrogen.
1. Hydrogen release kinetics of hydrogen storage alloys
The hydrogen-storing alloy is Metal Hydride (MH) n ) Endothermic decomposition into a metal (M) and hydrogen molecules (H) 2 ) Releasing hydrogen is a reversible reaction. The reaction formula is shown as follows:
(M is a hydrogen-storing alloy; MH n Is a metal hydride; delta H is heat of reaction)
From the above reaction, further discussion of the hydrogen absorption reaction process can be roughly divided into:
1) Hydride Decomposition (Hydride Decomposition):
the metal hydride alloy is used as a hydrogen source, and then a specific temperature and an environmental pressure lower than the platform pressure are applied to decompose the metal hydride of the hydrogen storage alloy to release hydrogen atoms, and the inside of the alloy is transformed from a beta phase to an alpha + beta phase and then to an alpha phase.
2) Diffusion (Diffusion):
all the hydrogen atoms dissolved in the alpha phase diffuse into the surface of the alloy.
3) Surface Penetration (Surface pennetration):
hydrogen atoms penetrate the surface of the alloy to the surface of the alloy;
4) Recombination (Recombination):
the hydrogen atoms on the surface of the alloy synthesize hydrogen molecules and absorb the heat of chemical synthesis.
5) Exit (Desorption to gas phase):
hydrogen molecules are desorbed from the hydrogen storage alloy into the hydrogen gas.
2. Hydrogen release rate of hydrogen storage alloy
The hydrogen release rate is expressed as:
wherein C d And E d The reaction time constant and the required activation energy when each alloy material is dehydrogenated are respectively as follows: c d ＝9.57sec -1 、E d ＝16473.0J/mole；P eq,d Balancing pressure for hydrogen discharge; rho s Is the alloy density; rho emp The density of the alloy after complete hydrogen evolution was 8310kg/m 3 ；R g Is the gas constant; t is the temperature. When the equilibrium pressure in the alloy is greater than the ambient hydrogen gas pressure and the alloy density is greater than the density of the alloy that does not absorb hydrogen, and the two pieces stand simultaneously, the alloy will perform the hydrogen discharge action, at this time m d Is negative.
3. Thermodynamic property of hydrogen absorption of hydrogen storage alloy
Then, the beta-phase metal hydride of the hydrogen storage alloy is decomposed into alpha-phase hydrogen-containing solid solution at a specific ambient temperature and pressure, and the hydrogen atoms dissolved in the alpha-phase are diffused to the surface of the alloy and reduced into hydrogen molecules, which are released into the environment according to the following formula:
Gibbs phase rule：F＝C-P+2
(F is the degree of freedom of the system, C is the number of components, and P is the number of phases)
Through the above formula conversion, a plateau region with constant pressure is generated in the phase diagram, and the pressure range of the plateau region is the effective released hydrogen content of the hydrogen storage alloy. And when the beta phase has completely transformed into the alpha phase, the slope of the hydrogen pressure/hydrogen concentration graph will decrease sharply. During the hydrogen release process, the phase change transition process can be observed from the P-C-T curve. It is shown in the literature data that as the temperature increases, the pressure at the platform of the hydrogen storage alloy increases, which accelerates the release of hydrogen from the alloy, as shown in FIG. 2;
as can be seen from the above, when both alpha and beta phases coexist, the P-C-T curve has a distinct plateau region where the equilibrium pressure (P) is eq ) The relationship between the temperature and the alloy hydrogenation equilibrium pressure can be obtained according to Van't Hoff's law:
ΔG＝ΔH-T*ΔS
( Δ G: gibbs free energy change amount,. DELTA.H: enthalpy change amount,. DELTA.S: entropy change amount, kp: equilibrium constant, R: ideal gas constant, T: absolute temperature )
In this way, the pressure can be plotted
And temperature
The slope and intercept of the curve can be known from the graph, so as to obtain the reaction enthalpy and reaction entropy change of the heat absorption and release of the hydrogen storage alloy, and the related characteristics of the hydrogen storage alloy are known, as shown in FIG. 3.
