Energy Effective Membrane-less Technology for High Pressure Hydrogen Electro-chemical Generation

Abstract

Water electrolysis process for hydrogen generation is widely used in various branches of industry. But it has disadvantages like important energy consumption and utilization of separate membranes, which limit the generated gases pressure.This article describes the hydrogen and oxygen generation technology excluding the separating ion-exchange membranes and providing high gases pressure due to applying the variable valence metal chemically active electrodes as well as due to separating in time and space the electrolytic processes of water decomposition for gases liberation.The electrolyzer based on this technology surpasses all of the known analogues by the level of technical decisions, simplicity of mounting and servicing, reliability and safety. ________________________________________________________________________________

Создание Автономных И Сетевых Энерготехнологических Комплексов С Водородным Накопителем Энергии

“…В процессе проведенных исследований сформированы принципы научно-технического развития электрохимических водородных систем и предложены пути оптимизации их работы на нестационарных режимах, характерных для реальных условий эксплуатации энерготехнологических комплексов на базе СЭС. В известных моделях электролизеров снижение энергозатрат достигается путем использования редкоземельных металлов платиновой группы в качестве катализаторов электрохимического процесса на поверхности электродов [14][15][16][17]. Это, в свою очередь, приводит к удорожанию оборудования, повышению требований к его обслуживанию, уменьшению ресурса эксплуатации.…”

Formation of potassium ferrate in a membrane-less electrolysis process of water decomposition

“…The measurement of the evolved gases volume was performed by the volumetric method using U-shaped differential manometers of the oxygen and hydrogen highways. The used method is similar to that described elsewhere [10,11].…”

“…Earlier, a method of high pressure hydrogen and oxygen electrochemical generation in the membrane-less electrolyzer was developed using metals with variable valence [10][11][12]. According to this method, the process of water decomposition is cyclical, namely, the processes of hydrogen and oxygen evolution are alternating in time.…”
