Solid oxide fuel cells (SOFC) stand as a promising technology for efficient and clean energyproduction. Ni-Fe/CeO 2 -ZrO 2 cermet exhibits Ni-Fe nanoparticles that promote H 2 and CH 4oxidation reactions. Our in-situ NAP-XPS and NEXAFS study reveals surface changes when H 2and CH 4 are used as fuels. We find a high catalytic activity for methane oxidation reaction andcarbon formation resistance. Information provided by the agent in SIGEVAKey Words
