Electric current supply system, designed to be at least partially submerged in an electrically conductive liquid during operation thereof

An electric current supply system (20) is designed to be at least partially submerged in an electrically conductive liquid during operation thereof, and having at least one electrically conductive component (21, 22, 23, 24) enveloped in liquid-tight material (40). The component (21, 22, 23, 24) has a sacrificial material that is capable of reacting electrochemically with the liquid. Further, the component (21, 22, 23, 24) has at least one gas trap portion (50) at which the sacrificial material occupies a space in the liquid-tight material (40) that is thereby defined with a gas trapping shape. If, in case of damage to the system (20) in an actual submerged state thereof, the component (21, 22, 23, 24) gets exposed to the liquid, it is achieved that an electrochemical reaction occurring at the exposed area of the component (21, 22, 23, 24) and an outflow of electric current to the liquid are stopped.

CATHODIC PROTECTION POLYPROPYLENE GRAPHITE REFERENCE ELECTRODE
20230295810 · 2023-09-21 ·

Disclosed herein is a reference half-cell including a tube including an electron interface made of polypropylene graphite, an electrolyte solution, a metal electrode, and a seal. Alternatively, the reference half-cell may be employed without an electrolyte solution and a seal. The electron interface along the first end of the tube may be either an integrated part of the tube or a component separate from and affixed at its ends to the tube to maintain the electron interface in a stationary position relative to the tube. The use of electrically conductive polypropylene for the electron interface provides a half-cell that has good electrically conductivity and high moisture inhibitiveness and, as a result, has an improved service life.

TWO TERMINAL CORROSION PROTECTION DEVICE, SYSTEM, AND METHOD
20210238751 · 2021-08-05 ·

A corrosion protection device, system, and method are provided. The device may operate while being coupled to the object being protected and to a power source using a total of only two terminals. This may be accomplished by de-referencing the return path node of the circuit using a choke device that blocks a temporal AC component of an anti-corrosion signal. The choke device therefore diverts the anti-corrosion signal to a single negative/ground path to the object and then returns through a positive lead of the circuit. A two terminal corrosion protection device may thereby simplify the installation process, for example on a vehicle, by not requiring that another connection be made to the object at a spaced apart location from a first connection to the object.
