During the last three decades, a large number of investigations has been reported pertaining to
the science and technology of solid oxide fuel cells (SOFCs) based mainly on the yttria-stabil-
ized zirconia (YSZ) electrolyte. Because of the problems associated with the high temperature
of operation ( ,-~ 1000 ~ of the YSZ-based cells, there has been a substantial effort to de-
velop alternative electrolytes with ionic conductivity comparable to that of YSZ at relatively
lower temperatures. This review presents a systematic evolution in the area of the development
of new electrolytes based on bismuth sesquioxide for fuel cell applications at moderate tem-
peratures.
1. Introduction
The modern scientific and technological approach in
the area of energy production is to develop inexpens-
ive devices, which would satisfy the current drive for
