Resumen de: US2025198012A1
The invention pertains to an electrolyser for producing hydrogen (H2) and oxygen (O2) as product gases. It includes an electrolysis module and a gas separator for phase separation of the product gas from water. The electrolysis module is connected to the gas separator via a product flow line, and a return line with a circulation pump connects the gas separator back to the electrolysis module for separated water. A bypass line with a valve allows water to be supplied from the gas separator to the electrolysis module during standstill. The invention also covers a method for operating the electrolyser, where in standstill mode, the electrolysis current is stopped, and a safety deactivation is initiated. Water is automatically driven into the electrolysis module due to a hydrostatic differential pressure (Δp) from a predefined height difference (Δh), flooding the electrolysis module.

Resumen de: US2025198023A1
An electrolyzer for gaseous production such as hydrogen gas includes an oscillating electrode driven at a natural frequency of the gaseous bubbles improves output by readily removing the gaseous bubble product from the electrode surface, thereby exposing greater electrode surface area for subsequent electrolysis reactions. A natural frequency of the gaseous product determines an oscillation frequency with which to drive the electrode accumulating the gaseous product, such as hydrogen bubbles, to agitate and release the bubbles which then rise to the surface of the liquid filled containment. Integrating oscillation logic for agitating the otherwise stationary electrode or cathode in a PEM water electrolyzer improves hydrogen production by readily evacuating the generated hydrogen to free up the electrode area for additional electrolysis reactions.
