Solid oxide fuel cell redox instability characterized by in situ transmission electron microscopy

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

A solid oxide fuel (SOFC) cogenerates heat and electricity with high efficiency. Electricity is produced by the electrochemical reaction of a fuel (H2, CO, CH4) and an oxidant gas (O2, air). The SOFC standard design is based on an anode-supported electroly ...

Sulfur as pollutant species on the cathode side of a SOFC system

Aïcha Hessler-Wyser

Sulfur poisoning in a strontium doped lanthanum cobaltite (LSC) cathode current collection layer was revealed in a solid oxide fuel cell (SOFC) tested in repeat-element and stack configuration. Sources of sulfur contamination, other than trace SOx in air, ...
