The design of a microfabricated air electrode for liquid electrolyte fuel cells
In this dissertation, the microfabricated electrode (MFE) concept was applied to the design of an air electrode for liquid electrolyte fuel cells. The catalyst layer of the electrode is envisioned to be fabricated by using a microfabricated die to apply a three-dimensionally patterned macro-texture …

Interactions of the Air Electrode with Electrolyte and Interconnect in Solid Oxide Cells
… between the ceramic electrolyte, porous ceramic air electrode, and metallic interconnect materials — including solid state interfacial reactions and vaporization/deposition of some volatile elements — have been investigated in the simulated SOC operating environment. The interactions demonstrate …

Understanding and Controlling the Surface Chemistry of Oxides to Enhance Catalytic Activity at Elevated Temperatures
… dopant precipitates during their operation as air electrodes in solid oxide fuel/electrolysis cells. The 4 effects of polarization on the surface degradation are explained by two different driving forces for dopant segregation to the surface of the air electrode. This dopant segregation and …

Chromium poisoning mitigation in solid oxide fuel cell air electrodes: mechanisms for Cr deposition and removal
Chromium poisoning of the air electrode remains a significant obstacle to the long-term performance of solid oxide fuel cells (SOFCs). Many strategies to mitigate this effect have been investigated. However, they require the introduction and development of new materials and components. Furthermore, …
