The role of surface lattice defects of CeO2−δ nanoparticles as a scavenging redox catalyst in polymer electrolyte membrane fuel cells† The present investigation deals with the optimization of the concentration of lattice cerium(III) and oxygen vacancy concentration, over the surface of CeO2−δ nanoparticles by varying the processing parameters. The higher value was found to be in good agreement with the smaller grain size and transformation of tetravalent lattice cerium .

Evaluation of the Effects of Nanocatalyst Infiltration on the SOFC Performance and Electrode Reaction Kinetics by Transmission Line Model Jaewoon Hong, Aman Bhardwaj, Yeon Namgung, Hohan Bae and Sun-Ju Song Abstract In this work, the effect of nanocatalyst infiltration on the SOFC performance and electrode reaction characteristics was comprehensively investigated by the application of electrochemical impedance (EI) spectroscopy.
