CERAMIC FOAMS AS CURRENT COLLECTORS IN SOLIDE OXIDE FUEL CELLS (SOFC): ELECTRICAL CONDUCTIVITY AND MECHANICAL BEHAVIOUR

摘要

Ceramic open cell foams with porosities > 90 vol.% and pore sizes < 700 μm may be used as gas distributors, current collectors and load bearing structural parts at the cathode or the anode side of a SOFC. We report about the electrical conductivities, creep resisitivities, and high temperature compressive strengths of La_(0.84)Sr_(0.16)Co_(0.02)MnO_3 perovskite foams.
