Síntesis y estudio de la serie la4bacu5-xmnxo13±d con potencial aplicación como electrodo en celdas de combustible de oxido solido (sofc)
Las celdas de combustibles de óxidos sólidos SOFC son dispositivos que basan su funcionamiento en la oxidación directa de combustibles para la producción de energía. Estas se han contemplado como posibles sustituyentes para las fuentes de energía con altas emisiones de gases efecto invernadero (GEI)...

Solid Oxide Fuel Cells (SOFCs) are devices based in direct fuels oxidation for the electrical energy production. These are seen as possible substituents for energy sources with high emissions of greenhouse gases (GHGs). Two of the main characteristics looked in modern SOFCs are the decrease of its operating temperature (600-700°C) and the implementation of the same electrode material for both anode and cathode (symmetric cells). In this research
the family of ordered perovskite with anisotropic structure La4BaCu5-xMnxO (LBCM) (x=0

4 and 5) was prepared
evaluated and studied under a series of analysis (structural study
stability in oxidant and reducing atmosphere
and finally chemical compatibility) as a function of increasing concentration of Mn within the phase; this in order to define its possible application as an electrode in SOFCs symmetrical. The study of the structural behavior was conducted based on an ordered phase tetragonal (P4/m)
resulting structures by increasing the concentration was of orders structure space group P4/m xR-3c xreducing atmosphere of 3% H2/N2 at 700°C for 6 hours. Finally material compatibility was verified with the electrolyte BCZY after heat treatment at 1000°C without showing any reaction.
