PROCESS WATER GAS MANAGEMENT OF ELECTROLYZER SYSTEM WITH PRESSURE DIFFERENTIAL

摘要

A system and method for inerting a protected space is disclosed. According to the method, process water is delivered to an anode of an electrochemical cell comprising the anode and a cathode separated by a separator comprising a proton transfer medium. A portion the process water is electrolyzed at the anode to form protons and oxygen, and the protons are transferred across the separator to the cathode. Process water is directed through a process water fluid flow path including a gas outlet, and a pressure differential is applied between the process water fluid flow path and a discharge side of the gas outlet to remove gas from the process water. Air is delivered to the cathode and oxygen is reduced at the cathode to generate oxygen-depleted air, which is directed from the cathode along an inerting gas flow path to the protected space.
