TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Method: Hydrogen from the second electrolyte is separated between the cathode cell and the anode cell, and oxygen from the first electrolyte is separated between the anode cell and the cathode cell.Separating hydrogen and oxygen from the second and first electrolytes respectively comprises passing the respective electrolytes through a hydrocyclone and a gas liquid separator.Water is added as water or as steam.Microwaves are applied to the electrolytes.The anode cells and the cathode cells are operated at at most 200 degreesC.The anode solution electrodes and the cathode solution electrodes are coated with a substance to increase the over-voltage of the undesired reactions of the catalyst ions.The anode solution electrodes and the cathode solution electrodes are shrouded with a non-conductor mesh to retain a stagnant layer of electrolyte on the surface of the solution electrodes to avoid undesired reactions of the catalyst ions.Modifiers such as boric acid are added to the electrolyte to maintain a good quality and consistency of the electrolyte.Modifiers such as surfactants are added to the electrolyte to make the surface of the anode and cathode electrodes aerophobic to minimize the formation of gas bubbles on the electrode surfaces.The electrode surface area is increased by grooving, by the use expanded metal sheets and creating pyramids on the electrode surface.Preferred Parameter: The DC current has a frequency up to several thousand pulses per second and an amplitude of at most 100 times the average value of the current.The pressure in the anode and cathode cells is at most 100 bars.Preferred Component: The electrolyte is water that is acidic or basic.    TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Component: Regenerative pumps are used to minimize the energy required to maintain pressure in the anode and cathode cells.The first electrolyte is an alkaline electrolyte and the electrolytic process in the anode cell to produce oxygen is carried out in an anode circuit and the second electrolyte is an acidic electrolyte and the electrolytic process in the cathode cell to produce hydrogen is carried out in a cathode circuit and the anode circuit and the cathode circuit are kept separate except for the electrical connections.The anode circuit further includes a secondary cathode cell and the cathode circuit further includes a secondary anode cell, the secondary anode cell having a secondary anode and a secondary anode solution electrode, the secondary cathode cell having a secondary cathode and a secondary cathode solution electrode, the secondary cathode and the secondary anode are connected by an external conductor, and the secondary cathode solution electrode and the secondary anode solution electrode are connected by an external conductor, the first electrolyte being passed from the anode cell to the secondary cathode cell to produce hydrogen therein before being recycled to the anode cell and the second electrolyte being passed from the cathode cell to the secondary anode cell to produce oxygen before being recycled to the cathode cell.
