A crew from Washington State College (WSU) and Nissan has built-in a catalyst layer into into metal-supported stable oxide gas cell (MS-SOFC), enabling profitable operation with a direct ethanol feed. A paper on their work seems within the Journal of Energy Sources.
The crew launched a Rhodium-Ceria-Zirconia (Rh/CZ) inside reforming catalyst layer to the MS-SOFC by infiltrating Rh, CeO2, and ZrO2 precursors into the stainless-steel (SS 430) assist.
With a direct feed of an ethanol answer (45 vol%) into the anode at 600 °C, the experimental outcomes present that the cell with the infiltrated 5 wt% Rh/CZ demonstrates an improved efficiency over a cell with out the catalyst layer by enhancing the inner reforming exercise of ethanol towards the manufacturing of synthesis gasoline.
The utmost present density improved from 0.3 A cm−2 to 0.4 A cm−2 whereas the long-term stability was additionally vastly improved.
Publish mortem cell evaluation reveals that the infiltrated catalyst layer can stop extreme coke deposition from the cell’s anode purposeful layer.
The proposed built-in reforming catalyst and MS-SOFC system is a promising pathway to allow bioethanol fed-SOFC expertise for future electrical automobiles.

In 2016, Nissan introduced it was researching and growing a Strong Oxide Gasoline-Cell (SOFC)-powered system utilizing bio-ethanol because the on-board hydrogen supply. (Earlier publish.) The corporate has engaged in various analysis partnerships on this space (e.g., earlier publish, earlier publish.)
