A new steam-fed electrolyzer aims to bridge the gap between liquid-water electrolyzers, many of which require exotic materials and intricate membranes, and solid-oxide electrolyzers, which require superheated steam and temperatures as high as 800°C. This ‘symbiotic’ electrolyzer, developed by Advanced…
