According to an aspect, a concentration of H2 in O2 released from one or more anode compartments of an electrolyzer is measured. It is checked whether the measured concentration exceeds a predefined threshold. If the concentration exceeds the predefined threshold, a mixture of water and a secondary gas is injected into the anode compartments. The injected mixture dilutes any H2 gas present in the anode compartments so as to keep a level of the H2 gas within safe limits (thereby avoiding the formation of explosive mixtures). According to another aspect, a determination of whether the electrolyzer is in a standby or a shutdown mode is performed. In response to the determination, a minimal flow of the secondary gas is periodically introduced into the anode compartments, so as to keep a level of the residual H2 gas within safe limits (thereby preventing the degradation of the catalysts).

A partition enhanced membraneless water electrolyzer system is described herein in which an absorbent or other bulk separation technique or separation media is used to selectively separate either oxygen over hydrogen or hydrogen over oxygen as they are produced via electrochemical reaction in the electrochemical cell of the system. A hydrogen-enriched gas product can exit the headspace of the electrochemical cell and a remaining oxygen-enriched phase can exit the headspace of a desorption chamber of the system that is fluidically coupled to the electrochemical cell. The oxygen-enriched phase can either be produced as a product or regenerated by transferring it (in a continuous or batch mode) to the desorption chamber, where an oxygen-enriched gas product is produced by changing the thermodynamic state of the separation media. A remaining/resulting oxygen lean phase can be returned to the electrolysis cell.
