My group has working on synthesis and modification of perovskites and related structures to be applied for electrodes in Solid Oxide Fuel Cell. Doping of metals on perovskite structure can alter thermal and electrochemical properties of materials. To understand the material behavior, phase structure, morphology, thermal expansion behavior, oxygen permeation flux, and impedance of materials are investigated. The potential materials will then be fabricated as electrodes for a single planar electrolyte-supported cell and tested for catalytic reaction under H2 fuel at intermediate temperature (500-800oC).
