Definitions
- the present invention relates to a method and a device for generating oxygen and their use in different fields.
- O concentrators So-called oxygen or O concentrators are used, for example.
- two molecular sieves are controlled alternately by sucking air in through an air filter, compressing it with a compressor and feeding it to the molecular sieves alternately via valves.
- the molecular sieves are filled with zeolites that absorb gases.
- the adsorption ratio of oxygen to nitrogen is shifted to nitrogen to a large extent by the pressure generated, so that almost pure oxygen leaves the molecular sieve, of which approximately a third is supplied to the user or patient.
- O 2 concentrators are generally faulty and susceptible.
- the compressors are correspondingly noise-intensive and the devices are bulky.
- the present invention provides two methods for generating oxygen.
- water is split into hydrogen and oxygen, which is the electrolysis known per se
- Breathing air is then added.
- the resulting hydrogen can then are converted back into water together with ambient air via a fuel reaction coupled to it, it being essential to the invention that the electrolysis and the fuel reaction are coupled to one another in such a way that they form a reaction cycle and can run simultaneously and continuously.
- the electrical energy released in the fuel reaction is then used to reduce the energy requirement for the splitting.
- the water obtained in the fuel reaction is fed back to the splitting.
- the electrical energy required to maintain the reaction cycle is generated either by the fuel reaction itself, which is coupled to the electrolysis, or by a second fuel reaction which proceeds separately from the latter, hydrogen being then additionally supplied to both fuel reactions, which is not from the Electrolysis comes from, or supplied by a separate energy source.
- the additional hydrogen required for this can be provided directly from a store, in particular a metal hybrid store or pressure store, the hydrogen being obtained according to an embodiment of the invention by means of a fuel reforming process of a fuel, for example sodium borohydride.
- a fuel for example sodium borohydride.
- the fuel can be methanol, for example.
- oxygen can also be generated in a second method by interweaving the electrolysis process and the fuel reaction in such a way that the intermediate step of transferring the hydrogen generated during the electrolysis into the fuel reaction is eliminated.
- water is catalytically split into hydrogen ions and oxygen ions on an anode side of a cell, the hydrogen ions moving through a polymer electrolyte membrane (PEM) onto a cathode side of this cell, in which they are converted catalytically back to water with ambient air , On the anode side, the oxygen ions react to give off electrons to form oxygen, which is then added to the air we breathe.
- PEM polymer electrolyte membrane
- the water obtained on the cathode side can be fed back to the splitting on the anode side.
- the electrical energy required to maintain the reaction cycle can be provided by an additional fuel reaction which takes place separately from the method, by supplying additional hydrogen, which can possibly be reformed from a fuel, to the latter.
- an electrolyzer is electrically connected to a fuel cell and for the transmission of fluids.
- the electrolyzer and / or the fuel cell are designed as a so-called PEM cell.
- a plastic membrane is used as the electrolyte, which carries out the ion transport and only conducts protons.
- the advantage of polymer membranes over potassium hydroxide solution as an electrolyte is above all the higher power density that can be achieved with them.
- a PEM cell is insensitive to impurities caused by carbon dioxide, which means that very pure reaction gases can be used and fuel cells can also be operated with air.
- this fuel cell corresponds to the reverse principle of the corresponding electrolysis cell.
- the hydrogen gas fed to the anode of this cell is oxidized, whereby it decomposes into protons and electrons due to the catalytic effect of the electrode (2H 2 - 4H + + 4e " ).
- the H + ions in turn reach the through a proton-conducting PEM membrane
- the electrons migrate to the cathode when the external circuit is closed and do electrical work in this way.
- the (impure) oxygen contained in the ambient air is then reduced and water is formed together with the protons (4e " + 4H + + O 2 ⁇ 2H O), so that the overall reaction to 2H 2 + O 2 - »2H 2 O results.
- the water obtained in this way is fed back to the splitting process on the anode side of the PEM electrolyser.
- the second-mentioned method can be carried out according to the invention in that an electrolyzer and a fuel cell are combined in one cell, preferably as a PEM cell.
- the step of generating the gaseous hydrogen from the electrolysis and forwarding it as the starting product for a fuel reaction is omitted, only one polymer membrane being used as the electrolyte.
- Water supplied is catalytically split into oxygen ions and hydrogen ions (H 2 O - »O 2" + 2H + ).
- the water ions are passed through the polymer membrane to the cathode side of the cell and there react to water catalytically with oxygen supplied from the ambient air 4H + + O 2 + 4e " -> 2H 2 O.
- the water thus created can in turn be returned and fed to the anode side of this cell.
- the oxygen ions then give off the oxygen according to 2O 2 " -» O 2 + 4e " with the release of electrons.
- the gaseous oxygen can then be removed from this cell and added to the breathing air of a user accordingly.
- the gaseous pure oxygen in the form of bubbles is formed on the anode side in the supplied water, which is then discharged and, in one embodiment of the invention, fed to a water separator in which the bubbles of the pure oxygen separate from the water and then this can be removed accordingly.
- the device according to the invention provides an electronic, preferably microprocessor-controlled control unit, also referred to as a so-called demand system, which only makes this part available to the user at the beginning of the inhalation phase, i.e. this specific amount is admixed to the user in the breathing intervals of his breathing air.
- an electrolyser is already suitable as a generator unit with relatively small dimensions while providing relatively small amounts of water as a starting material for generating oxygen.
- the resulting hydrogen can, for example, be catalytically discharged to the environment as a vapor via a combustion tube or, in the preferred embodiment in which the electrolyzer is coupled to the fuel cell, is converted back into water together with ambient air via the fuel reaction coupled to it.
- either a direct power supply connection or an exchangeable battery can serve as the supplier for the electrical energy for carrying out or maintaining the individual reactions.
- a further fuel cell preferably a direct methanol fuel cell, serves as the electricity supplier, the methanol optionally being provided via a cartridge system.
- the oxygen is collected in a memory, from which it can then be selectively removed by means of the electronic control unit and supplied to the user.
- the generator unit, the pressure accumulator, the supply line and the electronic control unit form a unit which is designed in such a way that it is portable as a whole unit, for example, it is suitable for carrying around the patient.
- the electrical energy required to carry out the oxygen generation is provided by an electrical energy source, preferably a mains connection.
- this electrical energy source can be stationary. It forms, so to speak, a "docking unit" into which the mobile unit of the device can be plugged in and coupled accordingly, so that the process of O 2 generation can then take place.
- the mobile unit is in its mobile state, separated from the energy source, for as long as usable how oxygen is in the storage.
- the pressure accumulator is empty, the mobile unit is reconnected to the electrical energy source to be filled with pure oxygen. The subsequent useful life of the mobile unit depends on the size of the pressure accumulator.
- the generator unit either has a separate inlet for the necessary water, through which it can be filled, for example from the pressure accumulator, or, in one embodiment of the invention, a connection which has a connection provided on the stationary "docking unit" for supplying water connected is.
- FIG. 1 is a block diagram showing the method and the device of the invention.
- FIG. 2 shows a schematic representation of a device according to the invention as a mobile unit.
- FIG. 1 shows a block diagram of the principle according to the invention for generating oxygen with a generator unit 1.
- the generator unit 1 consists either of an electrolyser which is coupled to a fuel cell or of a single PEM cell which performs the functions of an electrolyser and a fuel cell.
- the basic structure of such cells is generally known.
- the generator unit 1 is fed from a water reservoir 2 with water as the starting material. The corresponding reactions of the electrolysis and the fuel reaction then take place in the generator unit 1.
- the resulting pure oxygen is produced in the form of bubbles in the water present on the anode side of the generator unit 1. This is discharged together with the oxygen and fed to a water separator 3 in which the pure oxygen separates from the water, so that the water separator 3 serves on the one hand as an oxygen reservoir 4 and on the other hand as the water reservoir 2.
- ambient air is supplied via a line 5 in order to enable the conversion back into water.
- the resulting water like the nitrogen produced, is optionally discharged via a common line 6 via a water separator 7. After it has been collected in a water reservoir 8, the water is admixed again by the water reservoir 2 via a return line 9 to the supply water line 10, so that a closed circuit is formed.
- the pure oxygen from the oxygen reservoir 4 is supplied to the patient's breathing air via a supply line 11.
- An electronic control system 12 also called a demand system, which is controlled by a CPU 13, regulates the selective removal of the pure oxygen via a valve 14.
- the CPU 13 in turn controls the supply of water from a water refill system 16 via a valve 15.
- the CPU 13 or the demand system 12 can be connected to sensors that determine the respective need for pure oxygen depending on the inhalation of the user.
- the entire system is supplied with the electrical energy necessary for carrying out the control and for carrying out the splitting and conversion processes from an energy source (not shown), which can be designed as a rechargeable battery, power supply connection or as a further fuel cell, a current transformer 17 being used comes.
- an energy source not shown
- a current transformer 17 being used comes.
- Figure 2 shows schematically the device according to the invention, which consists of a mobile unit 18 and a stationary unit 19.
- the mobile unit 18 consists of an oxygen generator unit 1, a pressure accumulator 20 directly connected to it, in which the pure oxygen generated from the electrolysis is collected.
- a pressure reducer 22 is provided between the pressure accumulator 20 and a supply line 21 to a patient.
- the supply line 21 is coupled to an electronic control system 12 via a valve technology known per se, so that pure oxygen is removed from the pressure accumulator 20 only at certain times during the inhalation phase and is supplied to the patient's breathing air and the concentration of oxygen therein selectively elevated.
- the generator unit 1 of the mobile unit 18 is connected via an electrical line 23 to a power supply unit 24 of the stationary unit 19.
