Abstract
The increase in energy demand and the concerns regarding the environmental pollution led to the development of green energy sources. Solid oxide fuel cells (SOFCs) are electrochemical conversion devices operating at high temperatures (about 1000 °C) characterized by high efficiency, low emissions, fuel flexibility. With the aim to decrease the operation temperature down to 700 °C and below, new materials and processing technologies are currently under investigation. Several issues regarding material synthesis, characterization and testing will be addressed in this study.
