Definitions
- the invention relates to a method for the reversible storage of hydrogen and a hydrogen storage.
- the technical problem of storing hydrogen arises especially in the context of the hydrogen economy, which provides for the use of hydrogen as an energy source, i. H. wants to use as an energy storage and transport medium.
- Hydrogen can easily be produced from water by electrolysis, e.g. B. from solar power.
- the stored energy can be easily recovered thermally by combustion, but it can also be converted directly into electrical energy in fuel cells.
- the question of the storage of hydrogen, especially smaller quantities and especially for mobile applications (fuel cell cars) has not yet been satisfactorily solved technically.
- the object of the invention is to provide a method and an apparatus of the e. G. Way to be designed so that the hydrogen release at low temperatures is possible.
- Gaseous hydrogen is supplied to the storage device in order to load the storage device with hydrogen.
- This is the What ⁇ serstoff arrivedelektrode placed in the device by an appropriate system of pipes, channels, pores or the like.
- the gas space B. extends either up to the H-memory electrode (eg, by being executed even tube-shaped, or porous electric ⁇ LYTEN), or the hydrogen is brought very close to the electrode (eg. Up to a thin electrolyte layer on the Electrode).
- the hydrogen is then taken up by the storage electrode, which is made of a hydrogen storage material such.
- a hydrogen storage system should not only absorb the hydrogen, but should also be able to dispense it in doses if desired. In the fuel cell car, this happens when accelerating: When the accelerator pedal is pressed, the accumulator releases the necessary amount of hydrogen to the engine as soon as possible.
- the hydrogen storage When refueling the hydrogen tank, the hydrogen storage should provide the H2 gas presented quickly and readily, i.e. e.g. without the need for high pressures to resume.
- An electrically conductive hydrogen storage material is used for storage.
- the usable hydrogen is mainly stored on the surface or below the surface of the material, which is why the material with a very large surface, e.g. sponge-like or as a thin film on a conductive carrier, is brought into the device.
- the uptake and release is regulated via a charge layer on the surface of the hydrogen storage material. For this purpose, it is completely or largely covered with electrolyte. Using a counter electrode and a fine sett ⁇ bare voltage or current source, the charge can at the Oberflä ⁇ che and the hydrogen storage capacity can be changed.
- the hydrogen storage device according to the invention can also absorb or release hydrogen at a constant temperature and pressure.
- Devices in electrolysis e.g. B. for the electrolysis of water also for hydrogen production. This is broken down by the electric current.
- the memory described here does not carry out electrolysis: a charge passage at the electrode / electrolyte interface is not desired. Only a surface charge is to be generated.
- the pressure and temperature range in which the hydrogen is taken up or released is generally predetermined by the composition of the material. It is desirable to adapt the pressure and temperature to the technical requirements. So far, this has mostly required either the additional modules mentioned or a change in the composition of the material, but this also changes the storage properties. Modification of the storage properties without changing the composition of the storage material is therefore desirable.
- Electrodes immersed in an electrolyte and a voltage source connected to them is reminiscent of a device for electrolysis. New, however, is that hydrogen is not produced electrolytically (there is no charge transfer takes), but that he is released because chermaterials be changed by the elekt ⁇ roche mix double layer the properties of Wasserstoffspei ⁇ .
- a passage reaction at the counter electrode may be useful, but in principle the device can also be designed in such a way that only a double-layer charge is built up at the counter electrode. Then typical features such as diaphragms / separating membranes for the separation of cathode and anode space can also be omitted. The separate removal of oxygen required for water electrolysis is also not necessary.
- a typical feature of our invention is also the dependence of the storage capacity on the electrolyte-wetted surface. Even with conventional adsorption storage, the capacity depends on the surface, but what is new is that the surface wetted by the electrolyte is decisive for our device.
- the storage unit described here can also absorb hydrogen at a constant temperature and pressure or submit.
- the regulation takes place via a fine setting ⁇ bare voltage or current source which produces a charge layer on the surface of the hydrogen storage material. Therefore, heating or cooling devices and pumps or compressors can at least be constructed more simply and therefore more cheaply, or may even be omitted entirely. Since there is no need to heat up or reform a chemical substance, there are no latencies.
- the invention offers the possibility of improving the properties of already tried or future materials by making it possible to change their properties: since in our arrangement the charge on the surface of the materials can be varied, the electronic density of states and thus the hydrogen storage capacity can be changed , Given the urgent need for better storage, it offers a valuable option.
- the invention is based on the effect that the hydrogen storage in adjacent material is influenced by the charge in an electrochemical double layer.
- palladium foil 25 x 25 x 0.025 mm was used as the hydrogen storage material.
- a solution of lithium perchlorate in methyl acetate served as the electrolyte.
- the surfaces examined so far were relatively small, and therefore, with the previous test arrangements, only a very small adjustable storage capacity (especially in the Compared to the conventional storage capacity of the palladium). Therefore, gaseous hydrogen was not detected, but the change in the hydrogen storage capacity was detected indirectly via a current flow, in that the palladium foil was wetted on one side by phosphoric acid and glycerol in a double cell arrangement. The palladium foil could be loaded with hydrogen from this side.
- FIGS. 4 to 6 show current-time diagrams of hydrogen loads.
- Hydrogen uptake and release is regulated by a charge layer on the actual storage material set with the aid of an external voltage source
- the new type of hydrogen storage device consists of the following essential parts:
- the hydrogen storage electrode consists of an electron-conducting hydrogen storage material, e.g. As palladium, magnesium or magnesium alloys such as. B. Mg2Ni, Mg2Cu, Mg-Ln, or intermetallic compounds such as LaNi5, CaNi5 or LaNi4.7A10.3.
- the hydrogen storage material is carried out with a very large surface, e.g. B. sponge-like or as a thin film on a support. New is that a particularly large surface is used for the device presented here, with the usable storage area of our device with increasing ⁇ top of the hydrogen reservoir increases (in previous storing: Capacity depends mostly on the amount of the storage material).
- the storage material can also be applied to an electron-conducting carrier material.
- Both solid-state electrolytes and electrolyte solutions are suitable as the electrolyte, ie ion-conducting material.
- the electrolyte completely or largely covers the storage electrode, since the covered surface is important for usable capacity. Incomplete coverage may be necessary for technical reasons, e.g. B. to keep clear paths for gas transportation.
- the electrolyte must not be decomposed by the applied voltages, as no electrolysis should take place (work in the double layer area, capacitive charging instead of the Faraday process). Therefore, aprotic electrolytes such as salt solutions in methyl acetate or dimethylformamide may be more suitable than water, for example.
- the counter electrode consists of a material that conducts electrons well, eg metals such as gold or platinum. Base metals or conductive polymers that do not corrode in the electrolyte can also be used.
- the counterelectrode has a large area (to avoid high current or charge densities), which is why porous or rough material is
- the voltage and current source must be finely adjustable.
- the gas supply or discharge is, for example, a linear, branched or network-like system of fine capillaries, pores or tubes, which enable rapid gas transport.
- the hydrogen storage material 1 is applied as a thin layer on a conductive carrier material 2.
- the counter electrode 4 consists of tubes with pores for the hydrogen passage. The tubes are not wetting on the inside and conductive on the outside.
- the two electrodes are in contact with one another via the electrolyte.
- the hydrogen storage material 1 consists of branched nanotubes on a conductive carrier material 2.
- the hydrogen is fed in and out via the porous electrolyte 3.
- Fig. 3 shows an embodiment with a bipolar Elect ⁇ clearing arrangement.
- the conductive carrier material 5 serves as a counter electrode. The individual electrodes are separated from one another by insulators.
- Gaseous hydrogen is supplied to the storage device in order to load the storage device with hydrogen. This is achieved in the device using a suitable system of pipes, channels, pores or the like. brought to the hydrogen storage electrode.
- the gas space either extends to the H-storage electrode (e.g. by making it itself tubular or with porous electrolytes), or the hydrogen is brought very close to the electrode (e.g. up to a thin electrolyte layer on the electrode) ,
- the hydrogen is then taken up by the storage electrode, which is made of a hydrogen storage material such.
- the voltage source must be able to supply a constant current (galvanostatic operation) in order to enable an even release of hydrogen.
- the voltage used must not exceed the decomposition voltage of the respective electrolyte.
- the device presented here does not perform electrolysis: a charge passage at the electrode / electrolyte interface is not desired. Only a surface charge is to be generated. If the maximum voltage of the voltage source used exceeds the decomposition voltage, a voltage limit must be used.
- FIG. 5 shows a diagram in which the voltage was reversed every hour on the charge side (lithium perchlorate in methyl acetate).
- the curves contain a large proportion of electricity, which corresponds to the loading of the entire film with hydrogen.
- FIG. 6 the curves from FIG. 5 were adapted to a double exponential curve and this was subtracted.
- a current signal can now be clearly recognized due to the polarity reversal.
- the function of the potential on the loading corresponds to the expectation that the hydrogen charging of the palladium be ⁇ Sonders sensitive to a change in the electronic density of states in Pd, when the hydrogen loading is close to the phase transition ⁇ - ⁇ '.
