Cathodic and anodic overpotentials were measured using current interruption and AC impedance spectroscopy for two separate solid oxide fuel cells (SOFCs). The fuel cells used yttria-stabilized zirconia (YSZ) as the electrolyte, strontium-doped lanthanum manganite (LSM) as the cathode, and a porous YSZ layer impregnated with copper and ceria as the anode. The Cu/CeO2/YSZ anode is active for the ...

Calcium doped lanthanum and yttrium manganite electrode materials with oxygen deficiency and low polarization resistance (<30Ω*cm at 600°C) were tested in new advanced electrochemical sensor for the oxygen measurements. Oxygen sensor with oxide electrodes was showing fast response INTERNATIONAL JOURNAL ON SMART SENSING AND INTELLIGENT SYSTEMS, VOL. 5, NO. 1, MARCH 2012

Complexions at the Electrolyte/Electrode Interface In article number 2100967, Thomas Götsch and co-workers reveal that a complexion is formed between yttria-stabilized zirconia electrolyte lanthanum strontium manganite air electrode during sintering process of solid oxide cells. This nanometer-wide interlayer self-limited width characterized by partial amorphization compositional gradients. It ...
