Investigation of the microstructural effect of Ni-yttria stabilized zirconia anode for solid-oxide fuel cell using micro-beam X-ray absorption spectroscopy analysis

► Micro-beam XAFS Analysis was correlated to electrochemical performance of the cell. ► Ni/NiO fraction at different positions in the anode was shown. ► Oxidation status of Ni in the anode is sensitive to position.
