Abstract
Decreasing the operating temperature leads to an issue of high polarization that results in slow electrode kinetics. Infiltration of multi-cation oxide nanoparticle catalyst layer over the cathode backbone can provide low activation energy in catalyzing several electrochemical processes. The adoption of cetrimonium bromide(CTAB)-amino acid (glycine) route can become an efficient route to infiltrate particle with proper stoichiometry due to three-dimensional network forming nature owing to the zwitterionic form of the amino acid. Herein, we report a novel route for the development of discrete Sm0.5Sr0.5CoO3-?(SSC) nanoparticles on the cathode backbone. In particular, the full cell shows enhancement in electrochemical property with a power density of 1.57 W cm?2 at 700
