Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to electrolysis, and more particularly to electrolysis, in which mixtures thereof are generally
Concerns the electrolysis of hydrogen and oxygen, which is called "detonation gas".

Electrolysis is the process of passing an electric current through a liquid to cause a chemical reaction. If this liquid is water, the electrical sentinel "splits" the water into two divine gases: hydrogen and oxygen. When water is electrolyzed, hydrogen is collected at the cathode of the gas generator and oxygen is collected at the anode. Since pure water is not a good conductor of electricity, salts such as potassium hydroxide are added to the water to form electrically conductive solutions.1 Such bath solutions are known as electrolytes. By this process, gas is generated as a function of the surface area of the anode and cathode in contact with the electrolyte, and is generated in direct proportion to the flow of the gas flowing through the gas generator.

One of the important uses of the detonation gas generated by such means is as a fuel control for bath welding machines. In this type of application, the ratio of hydrogen and oxygen produced by electrolysis (two parts hydrogen to one part oxygen) corresponds exactly to the ratio required for recombination (combustion) in the welding torch flame.

Blast air generation devices used today are typically very bulky and inefficient. These devices have poor operating characteristics and are not ideal for use in mobile or portable devices.

Although numerous electrolysis patents have been published over the years, none have devised the efficient, compact, multi-cell structure disclosed and claimed in this invention.

In No. 1 and No. 4.124.4801', it is written as 5vC that the precepts are sent to the col. This is a W-like structure. This is because the current can be reduced in places where the electric current is high, so rectifier loss can be reduced and electrical efficiency can be increased. .

No. 3,451,906 and U.S. Pat. No. 4,014,777 disclose an apparatus in which a stream of liquid waste is illuminated with a number of lamps arranged in series and eleven rows. cells are used. Therefore, the cells all operate at the same level above and below water. This structure (・(Thus, rapid circulation of the electrolyte is promoted.) Speeding up the chain ring allows for cooling and at the same time ejecting generated gas to prevent contact between the Kameharu solution and the surface of the surface. This is desirable in order to maximize the linkage.

Thus, low operating temperatures and high gas evolution rates can be achieved.

What is noteworthy here is U.S. (China) Patent No. 4,014゜7.
The device described in No. 77 implements the unique characteristic previously mentioned, namely, the current flowing in series through the cells and the electrolyte flowing in parallel through the plates thereof. However, in the structure of U.S. No. 4,014,777, the openings forming one inlet hole and one outlet hole form a shunt current circuit, that is, a leakage current path between adjacent cells. Resulting in. Also, depending on the structure in which current flows in series, each cell has a different 1! Ki potential is applied. These leakage currents cause electrical losses that reduce the overall efficiency of the device. This same drawback is found in U.S. Patent Nos. 8,518,180 and 8,957.

Holes and Extrusions 1] They should be designed and arranged so that the ratio of length to cross-sectional dimension of the path through the hole is significantly greater than 1. Although the inlet and outlet tubes disposed in the device described in U.S. Pat. It is not possible to achieve the portability and low cost required for applications such as respiratory equipment. Indeed, among the modifications 191j disclosed so far, there has been no separation of hydrogen gas and oxygen gas during their generation.

In accordance with the present invention, a high efficiency gas generator is provided using a novel cell structure that provides a combination of electrolyte paths in parallel through several cells and current paths in series with the cells. This assembly has the characteristics of low cost, portability, and minimal leakage current.

Accordingly, one object of the present invention is to provide a new and improved electrolytic gas generator.

Another object of the present invention is to provide an efficient gas generator for producing hydrogen and oxygen gases.

Another purpose of the present invention is to be compact! l? An improved efficient gas generator using a series current path combined with a parallel current path through several cells of the generator in an efficient multi-cell gas generator. be.

Yet another object of the present invention is to improve the operating efficiency of the gas generator by physically configuring each component so that the electrolyte flows linearly in one direction and perpendicular to the flow of current through the cell. Increase. There is a particular thing.

Yet another object of the present invention is to provide simultaneous action of series current and parallel electrolyte flow coupled with a novel configuration of K11 artificial holes and outlet holes which effectively reduces leakage currents and the electrical losses resulting therefrom. It's about doing. .

Another object of the present invention is to provide an improved gas generation system that separates and releases the generated hydrogen and oxygen gases separately.

Other objects and advantages of the invention will become apparent from the description below. Hereinafter, the present invention will be explained in detail using the drawings.

One row of electrodes 21.4 to 2111. arranged at intervals in FIG. 'Electrolytic chaff) <-22, 4 to 22
Improved G8 electrolyte inlet ROM manifold 23, gas/decomposition ROM manifold 24, inlet hole 25, outlet hole 26, electrolytic Q, supply hole 27, gas/electrolyte delivery hole 28, anode terminal 29 and Yin-Yang terminal 31. The gas generator 20 shown in FIG. The generator 20 is connected to a sealed and electrically insulated nozzle 32.
Surrounded by tail. The housing 32 forms a cavity, and the chi V horn"-22 is inserted into the cavity.
A to 22G are formed. 'In the most important embodiment of the generator 20 of the present invention, the generator is used to electrolyze water to generate explosive gas. The solution used is potassium hydroxide (KOII)' (+
-Dissolved in water (at night).

Potassium hydroxide is used to provide electrical conductivity. The electrodes 21A to 21H are flat quadrilateral plates 1.

This plate is made of nickel sheet metal.

The operation of generator 20 will be explained. First, electrolyte 33 enters through hole 27 and fills inlet manifold 23 . Manifold 28 then enters chambers 22A-22G through inlet holes 25 to fill each chamber. Next, the outlet is passed through the hole 26 to the outlet manifold 24 and finally the hole 28
is discharged from.

It will be readily appreciated that chambers 22A-22G having inlet holes 25 and outlet holes 26 form parallel flow paths between inlet manifold 23 and outlet manifold 24.
It is what I am doing. Seen in cross section, the manifold 28
and 24 are sufficiently thick to minimize the pressure drop along their length. Furthermore, the inlet hole 27 is located at the bottom of the generator 20, whereas the outlet hole 28 is located at the top of the generator 20, so that the flow through one of the chambers 22A-22G is The total length of the path through which the electrolyte passes through any one of the remaining chambers will be the same as the total length of the path through which the electrolyte passes through any one of the remaining chambers. These measures ensure that the 'wLM liquid is delivered to all chambers at the same pressure and that the flow rate through all chambers is the same.

The current flow is as follows. That is, from the anode terminal 29 to the electrode 21A1 from the electrolyte in the chamber/'-22A to the electrode 21B1 from the electrode 21B through the channel 22Bk to the electrode 21C1 through the channel <-22C to the electrode 21D1 from the channel C-22D to the electrode 21E1 from the chamber 22E to the electrode 21F1 It flows from the chamber 22F, through the polarization 21G1, from the chamber 22G, through the electrode 21Ht, and through the cathode terminal 81. The electrodes 21A to 21H are
Since the conductivity is high, the 1-position difference between adjacent electrodes such as 21A and 21B and 21B and 21G is uniform over the entire surface facing each other. Since the electrolytic solution interposed between the electrodes has a high concentration and is constantly circulating, the current density flowing from the electrodes through the electrolytic solution to the electrodes is very uniform.

A voltage drop occurs between the electrodes, resulting in a potential difference between adjacent chambers. As a result of this potential difference, leakage current tends to flow from each chamber/bar to the adjacent chamber. Sunarichi, for example, chamber 2
Direct current leaks from 2A to chamber 221'j. Such leakage direct current traverses two paths. The first path is chaff); It exits through the hole 26 into the manifold 24 and then the juxtaposed exit hole 26 also leads to the chamber/bar 22B. In both cases the leakage current is carried by the electrolyte. 22C1 Chamber 22C to Chamber 22Z)
Under similar conditions, these leakage currents are unproductive in terms of gas generation.When leakage currents flow, they not only consume power but also reduce operating efficiency. Moreover, this is not preferable because it heats the electrolyte.

In order to minimize such leakage current, the cross-sectional areas of the inlet hole 25 and the outlet hole 26 are made small. Preferably, the length of each hole is several times larger than the cross-sectional diameter.

In each cha/bar of Chisan bars 22A to 22G,'
IL current flows from the electrode near the anode to the electrode near the cathode. Thus, the side of the plate electrode through which the current flows acts as an anode for the chamber, while the side of the other juxtaposed plate electrode through which the current flows becomes the cathode.

It is noted here that the back surface of the electrode that serves as a cathode for chamber 22A serves as an anode for chamber 22B. Electrodes 21B and 'polarized 21(,' to 21G) are thus known as bipolar electrodes, i.e. one side of each electrode is used as an anode and the other side as a cathode. Within each chamber, current flows from anode to cathode. When flowing into the anode, oxygen and hydrogen are generated.In other words, oxygen 84 collects at the anode,
Hydrogen 35 collects at the cathode. Both oxygen and hydrogen escape through the interchamber outlet hole 26 into the outlet manifold 24 with the electrolyte flowing through the chamber, and then into the collection chamber (not shown in FIG. 1) through the outlet hole 28.

The gas generator 40 of FIGS. 2 and 3 constitutes an alternative embodiment of the invention and is stacked between end covers or plates 37 and secured as a unitary device by a pole 41 and a nut 42. Contains a large number of flat or planar elements.

The end cover 87 is a quadrilateral plate 4 molded of nylon or a similar electrically insulating material that is impermeable to moisture.
Contains 3. Holes 44 around it are provided to receive bolts 41. 45.46 Artificial holes and outlet holes for two electrolytes (or for gas and electrolyte) on each end
is installed.

It should be noted that the holes 45 and 46 have a hollow cylindrical shape and/or a cylindrical configuration with their central opening 47 providing a passage through the cover 87. A screw terminal 48 is arranged in the center of the cover 37, and this terminal is connected to the contact button (
(not shown) and provides means for connection to the positive or negative terminal of the power source. Two such covers 87 are used in the generator 40. Sunawa'C:
)-t Disposed one at each end of the flat planar elements, FIG. 5 shows spacer elements 49 in the form of quadrilateral nylon frames. The long sides 51 and 52 of the element 49 are uniform in width, but the ends 53 and 54 are wider at one end than the other, and the width of the end 53 is the width of the width of the end 54. The light chambers are arranged diagonally. End 5
A wedge-shaped recess or notch 55 is disposed near the nip of each of 3 and 54. As will be described later, this recess serves as a passageway, ie, a channel, through which the electrolyte and gas flow. Two holes 58 are element 4
9 are arranged at each end of the hole -1, which serves as a passageway for gas and t passages. Further holes 59 spaced around the periphery of the element 49 are for passing the screws 41 of the gas generator 40. The broken line 61 indicates the recess 5
5 shows the outline of an equivalent element 49 turned inside out 17 so as to be placed at opposite ends 53 and 54 from the location of element 49 indicated by the dashed line.

FIG. 6 shows an electrode assembly 62 including a quadrilateral nylon electrode frame 68 and a quadrilateral plate electrode 64. electrode 64
is made of Nizukel when used in a blasting air generator. The frame 68 includes four sides of equal width with a central quadrilateral opening suitably dimensioned to receive the electrode 64 in a sliding fit. The external dimensions of the frame 68 are those of the element 49.
Counter holes 58, which correspond to the external dimensions of and are equally spaced apart, are provided as gas and electrolyte passages. Further, screw holes 59 arranged at equal positions are provided in the same manner as in the case of the element 49.

A narrow slot 65 extends inwardly from each of the four holes 58 parallel to the end members 66 of the frame 68 and stops short of a threaded hole 59 in the center of each end member 66. Slot 65 serves as a passageway for gas and electrolyte in generator 40 assembled as described below.

A cellophane separator element 67, which is also used as an element of the gas generator 40, is shown in FIG. The external dimensions of this element match those of the element 49 and the frame 63, and opposing holes 58 and 59 are provided at equal positions.

In the gas generator 40, the above-mentioned elements are stacked one on top of the other as shown in FIG.

When viewed from the top of FIG. 8, the stacking order is as follows. That is, electrode assembly 62, spacer element 49, cellophane separator element 67, spacer element 49, electrode assembly IJ-62, spacer element 49, separator element 67
, spacer element, etc., in this order. Every other element 49 is turned over as it is stacked so that the position of the recess 55 is alternated between one side and the other side. Generator 40 as shown in FIG.
In the cross-sectional view, the elmmen) 49, 62 and 67 are stacked in the same order as described above.

The interrelationship of holes 58, slots 65, and recesses 55 as they cooperate to form inlet holes, outlet holes, and manifolds for electrolyte and generated gases is shown in FIGS. 9 and 10. In FIGS. 9 and 10 two spacer elements 49 are shown superimposed. Spacer elements 49 are stacked one on each side of electrode assembly 62. One spacer element 49 is turned inside out with respect to the other spacer element 49 so that one recess 49 is to the left of the centerline of the gas generator and the other recess 49
is placed on the right.

As also shown in FIG. 9, the holes 58 of the two spacer elements 49 and the electrode assembly! The holes 58 in J-62 are aligned with each other, thereby forming a common passageway running perpendicular to the stacked elements. The four holes 58 in each element are stacked with the four holes 58 in other elements to form four passageways through the assembly.

Figure 9 also introduces the following. That is, the end of the slot 65 extending from the left hand hole 58 of the electrode assembly 62 communicates with the recess 55 of the spacer element 49 on the right side of the electrode assembly, whereas the end of the slot 65 extends from the right hand hole 58 of the electrode assembly. The end of the external force slot 65 is in communication with the recess 55 of the spacer element 49 on the left side of the electrode assembly 62. Therefore, it can be seen that the flowing electrolyte and the electrode The gas generated from the opposite surface of electrode 64 also flows freely upwards along the surface of electrode 64 and enters the recess 55 of the right-hand element 49 and exits through the slot 65 in the upper left-hand corner of the stacked element 49 shown in FIG. Matching hole 58
This means that it leads to a passage formed by. Similarly, the electrolyte and gas generated from this side of the electrode 64 travels along this side of the electrode 64 into the recess 55 of the spacer element 49 on the left side of the assembly shown in FIG. The other slot 65 then leads to the other passageway formed by the alignment hole 58 in the upper right-hand corner of the stacking element shown in FIG.

Electrolyte <H20+KOH> enters through two passages formed at the bottom by alignment holes 58. The electrolytic layer is then attached to the electrode frame 6
The spacer element 49 passes through the slot 65 of 8.
The concave portion 55 is reached. As shown in FIGS. 9 and 10, the electrolyte that has reached the recess 55 of the element 49 on this side exits the recess 55 and flows upward along the surface of the electrode 64 on this side, whereas recess 5 of element 49 of
The electrolytic solution discharged from the electrode 5 travels inside the electrode 64 and rises. When a current I flows perpendicularly from this side to this side of the electrode 64, the surface on this side of the electrode 64 becomes a cathode;
On the other hand, the surface opposite electrode 64 becomes an anode. The gas generated from the surface on this side of the electrode is hydrogen, and the gas generated from the surface on the opposite side is oxygen. Both of these gases move upward with the electrolyte flow. That is, the hydrogen 68 generated on this side surface escapes from the recess 55 of the spacer element 49 on this side through the slot 65 into the passage formed by the alignment hole 58 in the upper right hand corner of the gas generator. - force, oxygen generated on the opposite side 69
It exits from the recess 55 in the opposite element 49 through a slot 65 into a passage formed by an alignment hole 58 in the upper left-hand corner of the gas generator.

Slot 65 thus connects holes 25 and 2 of gas generator 20.
Inlet holes and outlet holes corresponding to No. 6 are formed. Making slot 65 long and narrow achieves the high electrical impedance necessary to ensure minimal leakage current from the inlet and outlet holes.

Although the cellophane separator 67 is not shown in FIGS. 9 and 10, it is placed in front of the element 49 on this side and behind the element 49 on the sural side. And this element 67 has an ionic current I
It allows the gas to pass through easily, but prevents the generated gas from flowing in the lateral direction. Since every other spacer element 49 is turned over and the positions of the recesses 55 are alternated, oxygen consistently flows to the left side of the gas generator, and hydrogen flows to the right side, as described above. Due to the action of the cellophane separator element 670, the generated oxygen gas and hydrogen gas are separated and sent separately from the gas generator 40.

The means for separating oxygen and hydrogen in the gas generator 40 will be further explained with reference to FIGS. 8 and 4. As shown most clearly in FIG. 4, the current I is applied to the first electrode 64, ! The solution 7L flows from left to right through the seven parator elements 67, the electrolyte 72 and the second electrode 64'. Thin film electrolyte? ■

This cellophane separator element 6'H% current I is allowed to flow through the cellophane separator element (at the same time as the oxygen generated on the surface 78 is

do.

The thin film-like liquid or liquid layers 71 and 72 are very narrow, their thickness being equal to the thickness of the spacer element 49, which can easily be made as thin as desired.

In this way, the electrode-to-electrode spacing can be reduced in this assembly without suffering from problems related to exact mechanical tolerances.

Since adjacent electrodes 64 and 64' are placed in close proximity, the length of the ion travel path is shortened, increasing electrical conductivity. Moreover, this narrow interelectrode spacing ensures that the degree of contact between the circulating electrolyte and the gas-generating electrode surface is maximized.

Thus, highly efficient and highly effective gas production is achieved in an assembly featuring separation of oxygen and hydrogen gases.

In the fully assembled generator 4o, the elements on both sides of the electrode assembly 62 are stacked in the order shown in FIG. End covers 87 are located at both ends of the stacking element.

Note that the holes 44 in the cover 37 are aligned with the holes 59 in the elmmen 49, 62 and 67. Front cover hole 4
5 and 46 are preferably located at the bottom of the assembly as shown in FIGS. 2 and 3.

In contrast, holes 45 and 4o in the rear cover are preferably located at the top of the assembly. The reverse is also possible. This is to equalize the length of the parallel electrolyte paths through the individual cells.

With the front cover 87 and the rear cover 87 overlapped and aligned as described above, screws 41 are passed through holes 44 and 59 and fixed in place with nuts 42. Tighten the nuts accordingly to create a sealed assembly. That is, the frame of the element is compressed all together and the electrolyte can be effectively confined.

It goes without saying that the effect of confining the electrolyte increases by coating the mating surfaces of the elements with a joint material or sealing material in advance.

FIG. 11 shows the generator 40 shown in FIG. A complete gas generator 7o is shown incorporating a power supply 71, an electrolyte and gas separation tank 72, and a pump 7B. pump? 3 is tank 72
It is connected in series to a tube 74 that extends from the bottom of the gas generator 4o to the inlet holes 45 and 46 of the gas generator 4o. A vertical wall 75 projecting downwardly from the top cover of tank 72 extends below the surface of the contained electrolyte 76 to form two chambers 77 and 78 for gas collection above the electrolyte. ing. The tube 81 connects the chamber 78 to the gas generator 40
The tube 82 communicates with the outlet hole 45 of the chamber 77.
It communicates with the outlet hole 46. Gas delivery lines 88 and 8
4 are arranged to extract gas from chambers 77 and 78, respectively.

power supply? The positive terminal of ■ is the terminal 4 on the inlet side of the gas generator 4o.
8, the negative terminal is connected to the terminal 48 on the outlet side. Since both terminals are in contact with the adjacent terminal electrodes 64, current is supplied from the power source and flows in series through the stacked elements of the gas generator B40, as described above.

Electrolyte 76 is drawn from the bottom of tank 72 by pump 73 and is delivered to inlet holes 45 and 46 of gas generator 4o. Upon entering the gas generator 4°, the electrolyte flows through paths parallel to the cells formed between the stacked electrodes.

The generated oxygen is released from hole 45, while hydrogen is released from hole 4.
Released from 6. Oxygen is transported to the chamber 78 along with the unreacted electrolyte through a tube 81, and hydrogen is also transported to the chamber 78 along with the unreacted electrolyte through the tube 82.
Carried to 7. This unreacted electrolyte is collected in tank 72, while hydrogen and oxygen are extracted through tubes 83 and 84, respectively.

Although the gas generators described above are designed to deliver oxygen and hydrogen separately, it may not be necessary to deliver such separate gases if, for example, the desired end product is blasting gas for welding. Therefore, elements 49 and 62 may have a simpler construction.

An example of a gas generator of the above type is a structure in which elements 49 and 62 are stacked in the order shown in FIGS. 12 and 13. It starts with the electrode assembly 62, the spacer element 49, the pole assembly 62, the spacer element 49, and so on. As shown, every other spacer element 49 is turned inside out, thereby allowing the electrode 6
The spaces in the regions of the recessed portions 55 on both sides of 4 are made not to coincide. This is because, if not arranged in this way, leakage current would be drawn from this point.

In the cross-sectional view of FIG. 18, elements 49 and 62 are stacked in the order just described with an electrode assembly 62 at each end. The current I flows from left to right through the stacked element, and the electrolyte 85 flows through the adjacent electrode 64.
from the bottom of the assembly to the top of the assembly.

The electrolyte flows in a thin film orthogonal to the current flow.

The generated blasting air 86 enters the recess 55 and slot 65 formed in the spacer element 49 and the electrode frame 68, respectively.
is discharged from the top of the assembly through an exit hole formed in communication with the top of the assembly. This perpendicular or orthogonal relationship between the current path and the electrolyte path allows the length of the current path to be minimized, thereby increasing operating efficiency. Flowing the electrolyte in parallel under pressure ensures that the area in contact with the highly concentrated electrolyte is maximized. The contact area reduced by the generated gas is minimized, resulting in a high gas generation rate. The darning effect is further enhanced by increasing the flow rate of the electrolyte.

The previously described embodiments of multi-cell gas generators are based on the concept of pressurizing and circulating an electrolyte through a narrow chamber within a cavity of the gas generator housing.

This concept was achieved by using two types of plastic frames and quadrilateral electrode plates stacked together as a cell assembly. The stacking structure and flow pattern for this type of multi-cell assembly was discussed in the discussion of FIGS. 1-18.

Another embodiment of the present invention is shown in FIGS. 14 to 21. In this embodiment, a gasket seal is used between the electrode and the multi-cell frame to prevent electrolyte leakage between the frames. Furthermore, the embodiment of FIGS. 14-21 has a reduced thickness than the electrodes shown in FIGS. 1-18, which saves material costs and allows for multiple inlets into each cell chamber. The incorporation of holes and exit holes allows for a more uniform flow pattern through each chamber.

As shown in FIG. 17, gas generator assembly 90 includes a plurality of nickel foil electrodes 91, gasket seals 92 and a multi-cell frame 93 in a special arrangement.

FIGS. 14 to 16 illustrate the multi-cell frame 93, gasket 92, and nickel foil electrode 91 in more detail than shown in FIG. 17.

The multi-cell frame 98 is the most important part of the gas generator Asemp'J-90, and a cell chamber is formed inside the multi-cell frame 98.
It is designed to form a slot 96, a plurality of spaced notches 97 at one end thereof, and a plurality of gasket threaded holes 98 and feed-through poles 99 for flow of electrolyte and generated gas. be done. Feed through hole 99, cross feed channel 95
, notch 97 and orientation slot 95
The two multi-cell frames 98 adjacent to each other are arranged so as to rotate 180 degrees as shown in the figure to provide a desired electrolyte and gas flow pattern.

Nickel foil electrode 91 is made of a very thin electrode with a thickness of about 76.2 microns. By making the electrode thinner in this way, not only can the material be saved compared to the structures shown in Figures 1 to 18, but the electrode also has flexibility, so there is no unevenness or unevenness in the assembly/prep. can also be handled. The need for a gasket to provide a good seal between the multi-cell frame 98 and the electrode 91 and adjacent frame 98 within the gas generator 90 is due to the flatness of the parts used when assembling the multi-cell gas generator. Depends on loading and uniformity.

Although it is possible to make precision parts and eliminate the need for gaskets, sealing the electrodes with gaskets provides more consistent quality in production.

Each row of feedthrough holes 99 in the various feet of the stacked multi-cell assembly forms a manifold so that any two electrode plates 9 with electrolyte paths
It is important to recognize that leakage current may flow even between 10 and 10 seconds.

To suppress leakage current in the manifold, the feedthrough holes 99 in each electrode 91 are insulated as shown in FIG. The insulation of these holes is achieved by compressing a gasket made of an elastic plastic material under the pressure of the bolts 41 and nuts 42. Seal the hole to prevent the electrolyte from leaking out.

The basic operation of the multi-cell generator shown in FIGS. 14-21 is similar to the operation of the gas generator shown and described in FIGS. 12 and 13. The electrolyte is introduced under pressure through the inlet hole 99 and fills all of the cell chambers 94 formed by multi-cell frames 98, not shown in FIG. 17, located on each side of the intermediate electrode 91. The power source is connected to a terminal 48 attached to the end plate or electrode 91.

As soon as current is applied to the gas generator, gas generation begins and gas bubbles are carried in both directions and enter both outputs simultaneously, as shown in FIG.

As can be seen from FIGS. 1 to 11, a gas generator that separately generates hydrogen gas and oxygen gas has been disclosed. 1st
The assembly shown in Figure 7 can be easily modified into an individual gas/gas generator by replacing every other electrode 91 with cellophane of comparable size. For example, if the electrode 91 in the center of the assembly shown in FIG. 17 is replaced with a cellophane sheet, hydrogen gas and oxygen gas can be separated as they are generated. Since the cellophane separator is disposed between the electrodes in this way, the gas generated on the anode surface does not mix with the gas generated on the cathode surface.

Also seen here are the multiple inlet and outlet holes cross-feed channel 9 formed by the notch 97.
5 promotes homogeneity of the flow pattern of the electrolyte and scum discharged from the gas generator through each chamber.

As a result of a test using a model of the gas generator according to the present invention,
A very high gas evolution rate was formed, and the discharged gas and electrolyte mixture showed a very high gas content. The gas to unreacted electrolyte ratio was high, and this was maintained even when the electrolyte flow rate was increased.

Thus, by using the principles taught in this invention, a highly efficient and effective gas generator is constructed.
