Planar copper containing anode-supported solid oxide fuel cells
Planar copper-containing anode supported Intermediate Temperature Solid Oxide Fuel Cells (IT-SOFCs) were produced by single step cosintering. The anode and the electrolyte were realized through water-based tape casting, the cathode being added by screen printing. A 5 mol% of Lithium oxide addition …
