Protonic rate level sensing device for an electrolysis cell

Abstract

A level sensing system includes a flow control device disposed in fluid communication with a liquid outlet stream of a hydrogen/water phase separation apparatus and a controller disposed in operable communication with the flow control device. The controller is configured to receive and quantify input data corresponding to a measure of the rate of generation of hydrogen gas from a proton exchange membrane electrolysis cell. A method of maintaining a liquid level in the hydrogen/water phase separation apparatus includes deriving the rate of generation of hydrogen gas from the electrolysis cell, transmitting a value corresponding to the rate of generation to the flow control device, and adjusting the flow rate of the liquid exiting the hydrogen/water phase separation apparatus correspondingly with the rate of generation of hydrogen gas.
