Route to High-Performance Micro-solid Oxide Fuel Cells on Metallic Substrates.

ABSTRACT: Micro-solid oxide fuel cells based on thin films have strong potential for use in portable power devices. However, devices based on silicon substrates typically involve thin-film metallic electrodes which are unstable at high temperatures. Devices based on bulk metal substrates overcome these limitations, though performance is hindered by the challenge of growing state-of-the-art epitaxial materials on metals. Here, we demonstrate for the first time the growth of epitaxial cathode materials on metal substrates (stainless steel) commercially supplied with epitaxial electrolyte layers (1.5 μm (Y₂O₃)_0.15(ZrO₂)_0.85 (YSZ) + 50 nm CeO₂). We create epitaxial mesoporous cathodes of (La_0.60Sr_0.40)_0.95
