LaCr0.75Mn0.25O3+δ –CGO nanocomposite electrodes for highly efficient Solid Oxide Fuel Cells

Abstract

One of the most recent strategies to enhance the electrode performance is the preparation of nanocomposite materials, leading to an increase of the triple-phase-boundary (TPB) length. In this way, spray-pyrolysis deposition has been proposed due to the fact that it is an easy method that has been applied previously to prepare nanocrystalline electrodes, with a significant improvement in comparation with traditional electrodes. In this work, a new nanocomposite based on manganese-doped lanthanum chromite (LCM) and gadolinium doped ceria (CGO) has been proposed for highly efficient and stable electrodes for Solid Oxide Fuel Cells.
