Formation of Y2O3 and Y2O3:Eu(III) by Electrodeposition in Organic Electrolyte.

Journal of the Surface Finishing Society of Japan, 1993
Formation of yttrium oxide by electrodeposition was studied in DMF containing YCl3 and a small amount of water, and rectangular pulse electrodeposition technique was applied. Y2O3 was formed during the electrodeposition, and Y2O3:Eu (III) film was formed also in DMF containing YCl3, EuCl3 and a small amount of water.

Support‐Driven Hydrogen Migration Enhances Ammonia Decomposition in Direct Ammonia Protonic Ceramic Fuel Cells

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Enhanced hydrogen species migration enabled by FN/BZY catalyst mitigates intermediate accumulation and improves DA‐PCFC performance during ammonia decomposition. Ammonia, with its high hydrogen density and carbon‐free nature, serves as ideal fuel for direct ammonia protonic ceramic fuel cells (DA‐PCFCs).
