St. Andrews Fuel Cells Ltd. is a spin-off company (formed in February 2005) from the University of St. Andrews. The company’s focus is on the development of the SOFCRoll fuel cell. The SOFCRoll design is produced from tape casting and is fired in a single unit, offering reduced fuel cell production costs. Additionally, the self-supporting nature of the SOFCRoll geometry removes the need for thick cell components, further reducing cell cost and offering increased power densities. This paper reviews the development of the SOFCRoll concerning the processing and performance testing.
