Solid Oxide Fuel Cells have still many technical problems related to its high operating temperature (800–1000°C). The most recent studies deal with reducing the operation temperature increasing at the same time the durability of the device. The use of La0.8Sr0.2Ga0.8Mg0.2O3-δ (LSGM) perovskite as electrolyte could be a very promising solution for IT-SOFC operating at 600°C. In this work, LSGM bilayers constituted by a thicker porous layer (namely the anode scaffold) and a dense electrolyte were produced by tape casting. The critical issues to obtain flexible and crack-free green tapes suitable for lamination were carefully examined. In particular, the nature and amount of pore former needed to obtain an anode scaffold with a porous network suitable for the catalysts impregnation process were deeply investigated.

Abstract
Solid Oxide Fuel Cells have still many technical problems related to its high operating temperature (800–1000°C). The most recent studies deal with reducing the operation temperature increasing at the same time the durability of the device. The use of La0.8Sr0.2Ga0.8Mg0.2O3-δ (LSGM) perovskite as electrolyte could be a very promising solution for IT-SOFC operating at 600°C. In this work, LSGM bilayers constituted by a thicker porous layer (namely the anode scaffold) and a dense electrolyte were produced by tape casting. The critical issues to obtain flexible and crack-free green tapes suitable for lamination were carefully examined. In particular, the nature and amount of pore former needed to obtain an anode scaffold with a porous network suitable for the catalysts impregnation process were deeply investigated.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
