Resumo
The Solid oxide fuel cell is a very efficient and clean source of energy. The planar design
of SOFC requires sealant at the edges of the cell to prevent fuel leakage (H2, CH4, etc) and air
mixing at its working temperature (700 to 900°C). The extreme operation conditions of current cell
designs involve both high temperatures and highly corrosive environments. As a consequence is
necessary a material to seal the chambers of the anode and cathode along each cell unit (the anodecathode-electrolyte and interconnects). The present work is an attempt to engineering glass
compositions based on the BaO-Al2O3-SiO2-B2O3 system chosen due its thermal properties and
good glass forming tendency. The glass formation or stability against crystallization and the
coefficient of thermal expansion were determined by Differential Scanning Calorimeter and
Dilatometric analysis, including sinterization curves. The main subject of this work is the
development and selection of sealing glasses composition for SOFCs applications and also the
development of new methodologies for preparation and evaluation of glass ceramics suitable for
SOFC seals applications.
