Water electrolyzers are electrochemical devices used to split water into its constituent elements, hydrogen and oxygen, by passage of an electrical current. There are four main types of electrolyzers: alkaline and proton exchange membrane (PEM) electrolyzers are already mature, while anion exchange membrane (AEM) and solid oxide electrolyzers are still under development. These technologies differ in numerous ways, most notably in cell design and variations within components. In this section you can find news items related to various aspects of electrolyzer technologies, equipment and components. If you would like to see your news release published here and in our email newsletter, please feel free to contact Matjaž Matošec.
