Screen Printed Porous La_(0.20)Sr_(0.25)Ca_(0.45)TiO_3 Fuel Electrode Scaffold Microstructures: Optimisation of Interaction with Impregnated Catalysts for More Durable Performance

摘要

La_(0.20)Sr_(0.25)Ca_(0.45)TiO_3 (LSCT_(A-)) shows promise as a novel Solid Oxide Fuel Cell anode backbone material (to replace Ni-based cermets). Thick film ceramic processing techniques have been used as the primary method in controlling the characteristics of the fuel electrode (layer thickness, porosity, grain connectivity and the ultimate interaction with catalyst particles) in order to produce a microstructural architecture which has the potential to deliver higher electronic (and ionic) conductivity, improved current distribution and more durable performance in fuel cell testing. Results of preliminary studies into the ceramic processing of LSCT_(A-) are presented here.
