Abstract:Solid oxide fuel cells (SOFCs) with flat-tubular structure were successfully fabricated by ceramic wet processing. The SOFCs had three or four internal channels for fuel gas flow and were supported by the fuel electrode. The SOFCs were composed of 8 mol Y 2 O 3 -ZrO 2 (YSZ) electrolyte, Ni-YSZ fuel electrode, and La 0.8 Sr 0.2 MnO 3 air electrode. Fuel gas was uniformly supplied to fuel electrodes with fuel gas pipes made of a heat-resistant alloy. The SOFCs had an active area of 50 cm 2 and were operated to a… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
