Publication number: 20220298659Abstract: An electrolytic method of loading hydrogen into a cathode includes placing the cathode and an anode in an electrochemical reaction vessel filled with a solvent, mixing a DC component and an AC component to produce an electrolytic current, and applying an electrolytic current to the cathode. The DC component includes cycling between: a first voltage applied to the cathode for a first period of time, a second voltage applied to the cathode for a second period of time, wherein the second voltage is higher than the first voltage, and wherein the second period of time is shorter than the first period of time. The peak sum of the voltages supplied by the DC component and AC component is higher than the dissociation voltage of the solvent. The AC component is selected based on a local minimum of a Nyquist plot to minimize energy loss while maintaining hydrogen transport.Type: ApplicationFiled: February 28, 2022Publication date: September 22, 2022Inventor: Dennis Cravens

Publication number: 20060226001Abstract: The system presented is an electrolytic cell and system for electrolysizing and/or heating a fluid electrolyte containing hydrogen in one of its several isotopic and compound forms having a conductive solution electrolyte. The electrolytic cell includes an electrically conductive electrode prepared of selected metals and/or their alloys. The cell is designed to release heat and/or reaction products during or after operation. The several electrodes are placed in electrical contact with the fluid electrolyte so that current passes between the several electrodes and made to flow through the electrolyte. The currents and voltages used between the various electrodes are chosen to be high enough to form ionization of some selected parts of the fluid electrolyte and move hydrogen in one of its various forms to the surface of one or more electrodes. Several geometric configurations such as microspheres, multicells, concentric electrodes and other forms can be used.Type: ApplicationFiled: April 8, 2005Publication date: October 12, 2006Inventor: Dennis Cravens
