Artigo IPEN-doc 19953 A fuel-flexible solid oxide fuel cell operating in gradual internal reforming2014 - NOBREGA, SHAYENNE D.; GELIN, PATRICK; GEORGES, SAMUEL; STEIL, MARLU C.; AUGUSTO, BRUNO L.; NORONHA, FABIO B.; FONSECA, FABIO C.An electrolyte supported solid oxide fuel cell (SOFC) was continuously operated with hydrogen, methane, and bioethanol for nearly 400 hours without adding water, O2, or CO2, and delivering a rather stable power output. Such a fuel-flexible SOFC was achieved by using both an anodic catalytic layer, which efficiently converts the primary fuel into hydrogen, and by the operation in gradual internal reforming conditions, which prevented degradation due to carbon formation.
