This disclosure relates to systems and methods for creating and using separators, containing boron species, that are used in electrolyzers. A disclosed separator for an electrolyzer cell includes a porous substrate having pores which provide a fluid path through the porous substrate from a first side of the porous substrate to an opposite side of the porous substrate, which is formed of one or more hydrophobic polymers or copolymers, and a coating that coats the pores of the porous substrate while maintaining the fluid path, where the coating is formed of an alcohol-containing polymer reacted with a boron-containing species.

This disclosure relates to systems and methods for gas separation in oxocarbon electrolyzers. A disclosed method includes supplying an oxocarbon to an input stream of a cathode chamber of an oxocarbon electrolyzer, converting the oxocarbon to a product gas in the cathode chamber, obtaining an output stream, with the product gas and residual oxocarbon, from the oxocarbon electrolyzer, and recycling a portion of the product gas, from the output stream, to the input stream.
