National Renewable Energy Laboratory - Visit the NREL Technology Transfer Website
Element One has developed thin films have the ability to quickly, reliably and cost-effectively detect the presence of dissolved hydrogen in liquids through either a visible color change or a measurable resistance change. Thin film sensors are multi-layer thin film devices incorporating a substrate, an active transition metal oxide layer, a discontinuous catalyst layer, as necessary nn additional protective layer. This invention may be used for early detection of fault conditions in transformer oils allowing low cost tests that can effectively Such thin films can also detect the presence of dissolved hydrogen in aqueous solutions for certain therapeutic heath drinks and other applications.
