Water electrolysis device and method for controlling the same

Abstract

An apparatus for water electrolysis includes a water-electrolysis stack, a feed-water pipeline, and a transport layer arranged upstream of the stack. A processor comprises pressures measured on each side of the transport layer and monitors ion conductivity of the feed water. When either reading crosses preset reference thresholds, the processor disables the power-supply unit and/or stops a circulation pump to protect the stack. The system can inject carbon dioxide to recover conductivity and issues alerts when the transport layer or an electrolyte membrane needs replacement, or when the carbon-dioxide charge falls below feed-water pressure. A complimentary control method performs the sensing, comparison, intervention, and user-notification steps.
