Abstract

Solid oxide cells (SOCs) are electrochemical devices for efficient energy conversion from fuel gas such as hydrogen, into electricity and inversely. SOCs are ceramic-based device composed of a dense electrolyte sandwiched by two porous electrodes. The oxygen electrode, also known as the air electrode, poses a significant challenge when working at intermediate to low temperatures. This presentation will present two strategies for enhancing the performance of oxygen electrode: i) improve the extrinsic activity by tuning the electrode active surface, and ii) increase the material intrinsic activity by cation substitution. This work focuses on lanthanum-praseodymium nickelate thin film deposited by Pulsed-Injection Metal Organic Chemical Vapor Deposition (PI-MOCVD) and on their structural and electrochemical characterization.
