High-throughput fabrication and electrochemical characterization of SOFC cathodes by combinatorial PLD

摘要

Preparation of novel materials with improved properties by the combination of different compounds which are only partially suitable for a defined reaction or system usually requires a considerable amount of time and resources. In this sense, combinatorial screening of materials is an emerging technique that allows obtaining a great amount of different compositions in a single experiment. Mainly, this methodology has been applied in the field of drug and biomolecules discovery, revolutionizing the pharmaceutical industry [1]. Nevertheless, in other fields remain unexploited because there is no an obvious way for its implementation, e.g. fuel cell materials. Bearing this in mind, combinatorial PLD presents the advantage of allowing the sequential deposition of different compounds which might be applied for the fabrication and study of multicomponent materials. In this work, we propose this novel strategy for the fabrication of a ternary system aiming to find a material with improved properties when operating as an SOFC cathode.
