BRIEF SUMMARY
The Recycling Hydrogen Generator is a safety compliant, flexible combination of filters and compartments for removing sodium and chlorine from the electrolysis process of generating hydrogen from water by remixing or recycling the NaOH+HCl residue into NaCl+H2O for reuse as new recycled electrolyte, preventing dangerous chlorine gases from entering the atmosphere, and allowing for the safe generation of hydrogen for individual automobile and home use as a source of electricity.
The flexibility is extended by anodes and cathodes with larger surface area or by the connection of multiple insulated anodes to each other and multiple insulated cathodes connected to each other, wherein the rate of hydrogen production is controlled and the control is increased by an attached hydrogen storage tank, a pressure sensor, rheostat and cut-off switch to cut off the electricity causing the electrolysis. The addition of a breakable window between compartments C-1, C-3 and C-4 allows for the instant remix of NaOH+HCl+H2 O residue with disproportionately created chlorine gas, in the event of a collision
The Recycling Hydrogen Generator combines and thereby improves upon various common knowledge technologies which have been patented already or discovered while working with the chlor-alkali process in order to solve problems such as preventing dangerous, disproportionately created chlorine gases from entering the atmosphere and controlling the production of only a safe amount of hydrogen.

DETAILED DESCRIPTION OF THE INVENTION
In FIG. 1 Internal Side View of chlorine gas filtration system shows the division of the approximately 12′′×8′′×12′′ sturdy, acid-resistant plastic housing into five compartments labeled C#1-C#5. The Figure {it} shows in C#1 the anode used for electrolysis; a vent or digitally controlled, re-sealable opening on the upper side for the addition of more salt water, and a re-sealable tube adjacent to the anode for the extraction of chlorine gas into compartment C#4. Compartment C#1 is divided from compartment C#2 into substantially equal sections by a broken line representing the PEM (permeable ion-exchange membrane) or ion-selective membrane which allows hydrogen and oxygen atoms to pass through it (after electrolysis has split the NaCl molecules) but not the chlorine or sodium atoms or H2 O molecules. A vent on the bottom of C#1 extends across the bottom of C#2, to allow the liquid remaining in both compartments, after electrolysis, to fall by gravity into compartment C#3. A breakable window on the left side of C#1 extends to the lower left side of C#3 for safety so that in case of accident, water and NaOH and HCl residue will mix with the dangerous chlorine gas contained in compartment C#4 immediately before any can enter the outside atmosphere due to damage to the outside housing or box, forming additional HCl, such as found in a normal car battery, which is much less dangerous than chlorine gas. FIG. 1 shows that compartment C#2 contains a cathode at the top with an adjacent closeable tube for the removal of hydrogen to a storage tank, and a vent for the addition of clean distilled water It shows that C#3 contains a vent on the lower left side for chlorine gas to be pumped from C#4 into the bottom of the solution in C#3 where the water or weak HCl serves as an additional filter (Filter 2) for the chlorine gases pumped into C#3, some of which will float to the surface, where a second vent above the solution level on the right side pumps any remaining chlorine gases created by disproportionality during electrolysis through a tube to the bottom of C#5 and a re-sealable vent on the bottom side which connects to the discharge or re-cycling tube for the liquid in C#3. FIG. 1 shows that compartment C#4 contains chlorine gas. It connects to the re-sealable chlorine gas tube adjacent to the anode in C#1. A vent on the bottom right internal wall allows the chlorine gas to be siphon pumped into the solution in C#3 to become HCl, and the breakable window that extends across the sides of both C#1 and C#3. Finally FIG. 1 shows that compartment C#5 has a vent and a tube from C#3 (above the solution level) to the bottom of C#5 where any remaining oxygen and chlorine gases can be filtered through a Na OH filter (Filter 3) and then 1a BaO2 filter (Filter 4) before being released from the generator so that only oxygen is a byproduct
In FIGS. 2 and 3, compartments C#4 and C#5 remain the same (although if C#3 also remains the same, the filtration system is improved), but the central combined compartment wherein C#1 and C#2 are combined by the elimination of the PEM and wherein this compartment can be expanded while C#3 is decreased in size has the addition of a very large surface zinc or zinc-plated or gold-plated (or half zinc-plated and half gold plated) titanium or steel anode (where zinc draws chlorine to it to form zinc-chloride, a solid which can be removed during maintenance cleaning while gold draws oxygen) and an equal size and shape rare metal or rare metal plated (preferably palladium which draws hydrogen) cathode. The zinc anode forms another filter (Filter 5) for removing chlorine gases, transforming them into less dangerous zinc-chloride.
FIG. 4 and FIG. 5 show an even larger surface anode and cathode system for a faster rate of hydrogen production comprising cylindrical or rectangular, zinc or gold plated wire mesh tubes as anodes and palladium-plated wire mesh tube cathodes, which are electrically connected anode to anode and cathode to cathode, but each individually insulated by a plastic wall sealed to the top of the said combined housing compartment C#1 and C#2 wherein this compartment can be expanded while C#3 is decreased in size, and wherein in the case of anodes the said insulating tube is sealed to the level 1 oxygen and chlorine vent and in the case of cathodes sealed to the level 2 hydrogen vent, but not touching the bottom of said combined housing compartment, where Na OH collects as a heavier molecule than hydrogen, oxygen or chlorine gas. There is a vent attached to the internal side wall of the said combined housing compartment to add fresh water. C#4 and C#5 remain the same, while C#3 is decreased in size or included in the said combined C#1 and C#2 retaining its vent above the liquid level entering compartment C#5, but a vent above each anode opens into a tube connected to C#4; while a vent above each cathode opens into a separate tube on a higher level for removal of hydrogen to a hydrogen storage tank. The said anodes and cathodes are spaced alternatively with anodes on one side of the said combined compartment and cathodes on the other so as to have access to the collection tube or vent level designated for them.
These variations in compartment, anode and cathode size in FIGS. 2, 3, 4, and 5 cause varying rates of hydrogen production requiring for potential safety standard regulation an external hydrogen storage tank attached to the other end of the hydrogen collector tube from the cathode vent, equipped with a pressure sensor, rheostat, and electrical cut-off switch to stop hydrogen production when the tank is full. An external vibration system is attached to the said housing to improve remixing of the Na OH+H Cl residue into Na Cl+H2O; and is attached directly to the insulated palladium-plated cathode series to remove the hydrogen from the palladium cathode (Filter 6), which common knowledge in the industry has shown to be a problem especially in small enclosures which clog up easily, and is attached to the zinc-plated anode to remove the zinc-chloride from the zinc anode (Filter 5) unless this process is controlled manually or mechanically.
