Abstract

Water electrolysis is a known process to produce hydrogen and oxygen from water. The electrolysis efficiency depends on the voltage needed to pass the desired current for desired time through the electrolysis cell to achieve the desired electro-chemical reactions. Motivation of present invention is to increase the electrical efficiency of electrolysis by reducing energy losses in the cell. This invention reduces energy losses by increasing ion density of the desired ions near to the respective reducing and oxidizing electrodes, which is accomplished in a hollow polyhedron, pyramid like, electrolysis cell by collecting ions from larger volume of the electrolyte solution with controlled electric fields, guided convection currents of the electrolyte solution with low grade thermal energy feed and steering the gathered ions close to the respective electrodes situated near to the top in the electrolysis cell.

Description

BACKGROUND OF THE INVENTION

This invention relates to an electrolysis cell, primarily to dissociate water into its elements—hydrogen and oxygen. Water electrolysis is a known process to produce hydrogen and oxygen from water. In this process, electrical energy dissociates water into diatomic molecules of hydrogen and oxygen. Water electrolysis is one of the typical examples of the subject matter in the study of Electrochemistry. For last many decades, faradic and nonfaradic processes are being studied extensively. Process variables such as electrodes, mass transfer, electrolyte solution, electrical voltage, electrical current, various temperatures, pressures, time are studied and analysed in detail. There is sufficient scientific literature on the electrolysis process and there are many patents related to electrolysis. Water electrolysis cell (electrolytic cell) is a container in which electrical energy dissociates water. Usually walls, bottom, top lid and connected pipes of the electrolysis cell are made of the material, which is non-corrosive, non-reactive to the electrolyte and is bad conductor of electricity in the electrolysis cell, electrolyzing electrodes that would carry electrical current when voltage is applied to these electrodes are fitted maintaining suitable distance between two adjacent electrodes. The cell is filled with water so that the electrodes are always immersed in water. This water in the electrolysis cell has some chosen electrical conductivity. At a certain voltage when applied to the electrodes, electrical current begins to flow through the water in the electrolysis cell. Passage of the electrical current liberates diatomic hydrogen as gas at one of the electrodes; and at the other electrode diatomic oxygen liberates as gas. Liberated hydrogen and oxygen gases are discharged through separate pipes. Usually electrolysis cell is leak protected.
Pure water is not a good conductor of electricity. At ambient conditions, a small but equal number of positive(H) ions and negative(OH) ions are always present in water due to natural dissociation of some water molecules. These ions attribute certain conductivity to water. However, natural water often contains some dissolved salts.
Sometimes it may also contain some dissolved acids or bases. These salts, acids or bases give more electrical conductivity to water as some of the dissolved salt, acid or base molecules dissociate into positive and negative ions of respective salt, acid or base. Conductivity of natural water is uncertain as it depends on percentage of various salts, acids or bases dissolved in water. When certain quantity of acid (e.g. Sulfuric Acid) or base (e.g. Potassium Hydroxide) is added and dissolved into the distilled water which is free from any salt or any other acid or any other base, the solution is the aqueous solution of that acid or base. The aqueous solution has controlled electrical conductivity at ambient temperature depending on the added quantity of the acid or base. The aqueous solution is in ionic equilibrium with solute ions and water ions, H and OH, as mentioned above. Under certain conditions, including reduction and oxidation potentials of the solute, passage of electrical current through the aqueous solution liberates diatomic hydrogen and diatomic oxygen at respective reducing and oxidizing electrodes leaving solute ions behind in the aqueous solution. Water electrolysis process uses aqueous solution of an acid or a base of controlled molarity in the electrolysis cell.
In principle, water could be dissociated into its constituents when the water molecules acquire necessary and sufficient energy under certain conditions. This energy could be supplied as electrical energy, light energy, ultrasonic energy, acoustical energy, thermal energy, chemical energy or some other form of energy that would dissociate the water molecule. In the electrolysis cell, electrical energy provides necessary energy to dissociate the water molecule into its constituent elements. However, the electrolysis cell has energy loss in the electrolyte solution and at the electrolyzing electrodes. These losses are not small. Thus, total energy needed for the dissociation of water in the electrolysis cell would be the theoretical dissociation energy of water and the energy losses in the electrolysis cell apart from electrical network losses that are outside the electrolysis cell.
Water electrolysis process to produce hydrogen is gaining more and more importance. Oil reserves are depleting faster than the discoveries of oil reserves at economical price. With this development, which most of the people think is unlikely to change, fuel prices would begin to soar steeply soon. Hydrogen may be the likely fuel for the automobiles in very near future. Hydrogen fuel has distinct advantage that it is pollution free. Moreover, hydrogen fuel cell produces electrical energy at very high efficiency that would facilitate the use of electrical motor to power the automobiles instead of I. C. engines. Though hydrogen can be produced using natural gas methane and water chemically reacting at high temperatures, the process produces carbon monoxide as the byproduct, which is hazardous. Natural gas is again a depleting fossil fuel reserve. Further, use of natural gas as automobile fuel may be the better alternative than using it to produce hydrogen and hazardous carbon monoxide. Water electrolysis is the better process producing pure hydrogen. Water electrolysis needs low voltage high current electrical energy source. Electricity is produced mainly by burning fossil fuel—coal, oil and gas and partly with hydro-power, nuclear energy and non-conventional energy. Electrolysis hydrogen cost thus depends on the electricity tariff. Therefore, improving the electrical consumption of water electrolysis process becomes very important.

Functioning Description

Following is the functioning of the present invention with reference to the accompanied drawings FIG. 1, FIG. 2, FIG. 3, and FIG. 4 for first embodiment:=
In this electrolysis cell the ledges 7 ab, 7 bc, 7 cd, and 7 da have simple yet effective function. These ledges contain the spread of the rising aqueous solution and ions under controlled conditions.
Low grade thermal energy feed pipes 5 c, and 5 d receive hot fluid at some pressure through pipes 5 c 3, and 5 d 3 respectively. When the electrolysis cell is filled with the aqueous solution, aqueous solution around the pipes 5 c, and 5 d absorbs some heat through the walls of the pipes 5 c, and 5 d. Return ports 5 c 1, and 5 c 2 of pipe 5 c; and return ports 5 d 1, and 5 d 2 of pipe 5 d return the cooled fluid to the heat tank for reheating. Aqueous solution heated around the pipes 5 c, and 5 d begins to move in upward direction and the cooler aqueous solution from the side canals enters into the canal accommodating the pipes 5 c and 5 d. Dispersion of hotter uprising fluid while rising along the surface of slanted trapezoid wall segments 1 b 2 and 1 d 2 above the thermal pipes 5 c and 5 d respectively is contained because of the respective ledges lab, and 7 bc for trapezoidal segment 1 b 2, and 7 cd, and 7 da for trapezoidal segment 1 d 2. Convection current is thus set in up direction along the wall 1 b 2 and 1 d 2. The hot aqueous solution above the electrodes when enters into the pipes 9 a, and 9 c, it dissipates the heat and the cooler fluid descends into the polyhedron along Trapezoidal segments 1 a 2, and ad2 respectively.
The electrolysis cell, which is the hollow polyhedron, is filled with the aqueous solution of an acid or base of suitable molarity. The electrolysis voltage is applied to the electrodes 4 a and 4 b situated in the upper part of the partitioned hollow of the polyhedron member 1. At certain voltage, electrolysis of water starts. Hydrogen ions move towards electrode 4 a which would be the reducing electrode and hydrogen is discharged as gas at the electrode 4 a. Liberated hydrogen is released through the pipe 5 a. Oxygen is liberated at the oxidizing electrode 4 b in the other partitioned hollow and is discharged through the pipe 5 b. Electrical flat conductor assembly 6 a, 6 b, 6 c, 6 d, 6 e, and 6 f are excited with pulsed voltages creating double layer capacitance conditions. Under the influence of controlled voltages more of positive ions tend to move and gather towards slant trapezoid face 1 b 2 while negative ions tend to move and gather towards opposite slant trapezoid face 1 d 2. Controlling voltage make these ions move upwards along the trapezoid faces 1 b 2 and 1 d 2 respectively. These accumulated ions finally discharge at respective electrodes as hydrogen and oxygen gas. Accumulation of the ions from larger volume and their delivery into a smaller volume reduces the resistance of electrolysis cell and thus improves the electrical consumption of electrolysis.
With excitation of electrodes assembly, of electrodes like 4 c, and 4 d, mounted inside the hollow polyhedron more of positive ions tend to move towards slant trapezoid face 1 b 2 while negative ions tend to move towards opposite slant trapezoid face 1 d 2 which enhances the effect on ion accumulation due to the energised electrical flat conductors alone.
Convection current set by low grade thermal energy feed expedites and augments the increase in ionic density, which reduces the resistance further and improves the electrical consumption for electrolysis.
For the second embodiment with FIG. 5 above functioning description holds with the same component nomenclature.
It is also understood that the examples and embodiments described herein are for illustrative purposes only and that various modifications or changes in light thereof will be suggested to persons skilled in the art and are to be included within the spirit and purview of this application and scope of the appended claims.
