Understanding of Long-term Phase Stability and Degradations in Solid Oxide Fuel Cells
EMSL Project ID
26712
Abstract
We plan to study the degradation mechanism and phase transitions in solid oxide fuel cells (SOFCs). Specifically, we plan to propose (a) Study of phase separations in SOFC cathode (LSCO) and (LSCF) as a function of various fuel cell exposure conditions including presence of gas phase contaminants. (b) Reduction and reversibility studies of Ni-O in yittria-stabilized zirconia (YSZ) environment as SOFC anode to understand effects of annealing conditions on Ni-O size-distribution and reactivity of Ni catalyst.
