AB  - BaCe0.9Eu0.1O2.95 (BCE) powder was synthesized by citric-nitric autocombustion
method. According to Rietveld analysis, BCE also possesses slightly larger unit cell
volume than mostly investigated BaCe0.9Y0.1O2.95 (BCY), which allows higher
proton mobility through the perovskite lattice. Sinterability of BaCeO3 is enhanced
by doping with Eu since dense electrolyte microstructure with 1–2 μm grains can be
obtained at temperatures below 1500 ºC. Conductivity measurements revealed
separate bulk and grain boundary contributions to the total electrolyte conductivity
below 200 ºC. The grain boundary conductivity was one order of magnitude higher
than the bulk conductivity, indicating the blocking effect of the grain boundaries to
the mobility of charge carriers. As this effect ceased with temperature, it was
possible to determine only total conductivities above 500 ºC. Conductivity of BCE
in a wet hydrogen atmosphere at 600 ºC reached 1.2 × 10–2
S/cm, which can be considered as one of the highest conductivities among BaCeO3 based proton
conductors. Thus, doping of BaCeO3 with europium offers multiple improvements
that can eventually lead to decrease in operating temperature of SOFCs based on this
type of proton conducting electrolyte
