High Quality, Dense Thin Films Using Metal/Metal Alloy Additives

Stage: Development

Berkeley Lab researchers Mike Tucker, Grace Lau, and Craig Jacobson have invented a novel layered structure for preparing a high-operating temperature electrochemical cell.



The structural support is porous metal, an unconventional approach which imparts strength, while use of the more expensive ceramic and cermet materials is confined to the thin active layers. Due to several unique processing techniques, a wider range of catalysts can be introduced into the structure than current methods allow. The Berkeley Lab process renders a robust, well-bonded electrochemical device that could be manufactured at significantly reduced cost.
