Open the CIPO recordAbstract From the Canadian patent
The superconducting properties of superconducting compounds are controlled or maintained by active external electrochemical intervention. The superconducting compound forms one electrode in an electrochemical cell. A counterelectrode and the superconducting compound electrode are in contact with an electrolyte and a potential is applied between the counterelectrode and the superconducting electrode. The cell is operated at a temperature near the expected transition temperature of the superconducting material. The potential applied between the electrodes is selected to control a property such as transition temperature. In a preferred embodiment a superconducting material, such as Ba2YCu307-x …
