A method of preventing degradation of an ionomer in an electrolyzer, comprising including in the electrolyzer an organic inhibitor, and operating the electrolyzer.
A method for preventing hydrogen crossover in an electrolyzer comprising including in the recombination layer of the electrolyzer an organic inhibitor, and operating the electrolyzer.
An electrolyzer comprising (a) electrodes, (b) membrane, and (c) electrolyte, wherein the electrolyte comprises organic inhibitor.
A method of extending the lifetime of ionomer and or membrane material in an electrolyzer comprising adding organic inhibitor into an electrolyte put into the electrolyzer, and operating the electrolyzer.
