Benefits of technology

[0010] It is a first objective of the invention to provide an apparatus for generating hydrogen and oxygen in which the polarities of the electrodes within electrolytic cells are intermittently switched to reduce the accumulated effect of plating the electrode material from one electrode to another.

Problems solved by technology

One problem associated with the operation of such apparatus arises from a tendency of metals used to form the anode(s) to form ions that are electrodeposited on the cathode(s), depleting material from the anode(s) and causing a possibly uneven and undesirable growth of material on the cathode(s).

Embodiment Construction

[0024] The invention will first be described with reference being made to FIGS. 1 and 2. FIG. 1 is a plan view of apparatus 10 for generating hydrogen and oxygen by electrolysis of water, and FIG. 2 is a cross-sectional elevation of the apparatus 10, taken as indicated by section lines 2-2 in FIG. 1 to show electrolytic cells 12 therein. The apparatus 10 includes a generator housing 14, holding the electrolytic cells 12, and a conduit housing 16, to which a hydrogen receiving conduit 18, and an oxygen receiving conduit 20 are attached. Each of the electrolytic cells 12 includes an electrode 22 and a container 24 holding a portion of an electrolytic fluid 26, including water, in contact with the electrode 22. A housing base 27 of the generator housing 14 additionally includes an electrolyte channel 28, extending among the various electrolytic cells 22 to hold a portion of the electrolytic fluid 26 in communication with each of the electrolytic cells 12 through a lower opening 30 in t...

Abstract

An electrolytic generator for producing hydrogen and oxygen switches polarities of electrodes to minimize the accumulation of electroplated electrode material driven from one electrode to the other. The generator contains two or more electrolytic cells in a lower portion, with an upper portion, including gas receiving receptacles. Preferably, water extends upward past a division between the upper and lower portions. In a first version, the upper portion, which is attached for gas collection through flexible hoses, is moved from one cell in the lower portion to another when the polarity is switched. In a second version, the upper portion remains stationary while the lower portion is moved to another upper portion as the polarity is switched.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] This invention relates to apparatus for the generation of hydrogen and oxygen by the electrolysis of water. [0003] 2. Summary of the Background Art [0004] Conventional apparatus for generating hydrogen and oxygen by the electrolysis of water includes at least one anodic cell, and at least one cathodic cell, with the cells being filled with a common electrolyte, including water and a salt making the water electrically conductive. An electrical current is driven through the electrolyte between a positive electrode, or anode, within the anodic cell(s) and a negative electrode, or cathode, causing the water molecules to dissociate into positive hydrogen ions, which are driven to form hydrogen bubbles at the cathode(s), and into negative oxygen ions, which are driven to form oxygen bubbles at the anode(s). [0005] One problem associated with the operation of such apparatus arises from a tendency of metals used to form the...
