 Solid oxide fuel cells (SOFCs) efficiently convert chemical energy directly into electricity, with only water as product. They are typically built in large scale and for stationary applications, due to the high operating temperature (600 to 1000 °C), therefore their applications are difficult for small scale power sources. However, SOFCs bear inherent advantages over current room temperature fuel cells, and recently several efforts have succeeded on reducing the operating temperature, either with thinner electrolyte or enhancement of catalyst/electrolyte interfaces. In particular, thin film electrolyte significantly reduces the Ohmic resistance of SOFCs and allows low temperature operations (250 to 400 °C). This talk will introduce a high-power density low temperature solid oxide fuel cells fabricated by means of micro- and nano-fabrication processes and atomic layer deposition (ALD).
