In previous works. we reported that Solid Oxide Fuel Cells (SOFCs). having a room-temperature sputtered and then annealed GDC thin film as the cathode/electrolyte barrier layer. had showed a huge increase of the output current (up to +78%) and a decrease of the ohmic resistance (up to -42%) as compared to fully screen-printed industrial SOFCs. https://www.roneverhart.com/Ryukyu-Kobujutsu-Buki-Jutsu-Vol-2-DVD-with-Kiyoshi-Yogi/
