Efficient Hydrogen Oxidation Catalyzed by Strain-Engineered Nickel Nanoparticles

Xile Hu, Weiyan Ni, Pascal Alexander Schouwink, Teng Wang

The hydroxide-exchange membrane fuel cell (HEMFC) is a promising energy conversion device. However, the development of HEMFC is hampered by the lack of platinum-group-metal-free (PGM-free) electrocatalysts for the hydrogen oxidation reaction (HOR). Now, a ...

Analysis of High Temperature Degradation of Alloys in Solid Oxide Fuel Cell

Manuel Bianco

Solid oxide fuel cells (SOFCs) are approaching commercialization to improve power production efficiency. Currently, cost and lifetime reliability limit their spread in the market. The SOFC is ceramic-based, but refractory metal alloys are in fact the major ...

Real-time optimization of an experimental solid-oxide fuel-cell system

Dominique Bonvin, Christophe Salzmann, Jan Van Herle, Zacharie Wuillemin, Alejandro Gabriel Marchetti

There still exists a large gap between simulation work and industrial applications in the context of control and optimization of solid-oxide fuel-cell (SOFC) systems. In an effort to bridge this gap, this study describes the experimental implementation of ...

Segregation of Nickel/Iron Bimetallic Particles from Lanthanum Doped Strontium Titanates to Improve Sulfur Stability of Solid Oxide Fuel Cell Anodes

Andre Heel, Oliver Kröcher, Davide Ferri, Patrick Simon Steiger

Perovskite derived Ni catalysts offer the remarkable benefit of regeneration after catalyst poisoning or Ni particle growth through the reversible segregation of Ni from the perovskite-type oxide host. Although this property allows for repeated catalyst re ...

Sulfur Poisoning Recovery on a Solid Oxide Fuel Cell Anode Material through Reversible Segregation of Nickel

Jan Van Herle, Andre Heel, Hossein Madi, Oliver Kröcher, Davide Ferri, Patrick Simon Steiger

The perovskite-type mixed oxide La0.3Sr0.55Ti0.95Ni0.05O3-delta (LSTN) is demonstrated to exhibit the remarkable property of structural regeneration, where Ni can be reversibly exsoluted from the host perovskite lattice resulting in a regenerable Ni cataly ...
