Solid Oxide Fuel Cell

Solid Oxide Fuel Cells (SOFCs) are attractive for their high energy conversion efficiency in the usage of fuels ranging from hydrogen to hydrocarbons. One of the biggest engineering challenges of SOFCs is their high operating temperatures, usually above 800 °C. Such temperatures diminish the SOFCs practicality for applications such as portable power sources. Therefore, our goal is to enable lower temperature efficient operation of SOFCs.

Our fuel cell research contains two fundamental parts: electrolyte and electrode. We applied our expertise in atomic layer deposition (ALD) and nanopatterning to engineer the desired properties of electrolytes and electrodes.
