Resumen:
The mechanism of Fe-Ni nanoparticle exsolution from Ni-doped Sr(Ti,Fe)O3-δ for solid oxide fuel cells (SOFC) is studied using electrochemical impedance spectroscopy and synchrotron-based near ambient pressure X-ray photoelectron and absorption spectroscopies while redox-cycling. Understanding and control of the exsolution is key to lowering SOFC operation temperature.
