The present invention provides novel compositions that find advantageous
use in making electrodes for electrochemical cells and electrochemical
devices such as solid oxide fuel cells, electrolyzers, sensors, pumps and
the like, the compositions comprising cerium-modified doped strontium
titanate. The invention also provides novel methods for making and using
anode material compositions and solid oxide fuel cells and solid oxide
fuel cell assemblies having anodes comprising the compositions.
