Nickel-Zirconia Anode Degradation and Triple Phase Boundary Quantification from Microstructural Analysis

Jan Van Herle, Aïcha Hessler-Wyser, Antonin Faes

Microstructural evolution of anode supported solid oxide fuel cells (SOFC) during medium-term stack testing has been characterized by scanning electron microscopy (SEM). Low acceleration voltage SEM imaging is used to separate the three anode phases (nicke ...

In situ Reduction and Oxidation of Nickel from Solid Oxide Fuel Cells in a Transmission Electron Microscope

Jan Van Herle, Aïcha Hessler-Wyser, Quentin Thomas Jeangros, Antonin Faes

Environmental transmission electron microscopy was used to characterize in situ the reduction and oxidation of nickel from a Ni/YSZ solid oxide fuel cell anode support between 300-500°C. The reduction is done under low hydrogen pressure. The reduction init ...

In situ reduction and oxidation of nickel from solid oxide fuel cells in a Titan ETEM

Jan Van Herle, Aïcha Hessler-Wyser, Quentin Thomas Jeangros, Antonin Faes

Solid Oxide Fuel Cells (SOFC) common technology is based on anode- supported cells composed of nickel-yttria stabilized zirconia (Ni-YSZ) cermet. The nickel is in oxide state (NiO) during SOFC production and is reduced to metallic nickel during the first o ...
