Hydrocarbon activation in solid state electrochemical cells☆

Improvement of a reduction-resistant CeSmO electrolyte by optimizing a thin BaCeSmO layer for intermediate-temperature SOFCs

“…Significant efforts have been devoted to the development of intermediate-temperature solid oxide fuel cells (SOFCs) [1][2][3][4][5]. This type of SOFC shows an advantage of avoiding the solid-state reaction of the fuel-cell components under operating conditions, providing long-term stability to fuelcell stacks [6].…”

Thermomechanical and conductivity studies of doped niobium titanates as possible current collector material in the SOFC anode

“…These problems have fuelled research into alternative materials for use in anodes. Examples of materials under investigation are ZrO,-Y_,O3-TiO~ systems, due to the compatibility with the YSZ electrolyte [1], and CeO~ based materials [2], which exhibit mixed conduction in the reducing environment.…”

Solid Oxide Fuel Cell Anode Materials for Direct Hydrocarbon Utilization

“…[ 59 ] Niobia-ceria and LiFeO 2 were also reported to be modest catalysts towards the electrochemical oxidation of CH 4 and C 3 H 6 . [ 60 ] While tracing the history of solid oxide electrochemical cells fed with hydrocarbon fuels three decades ago, this paper is aims to review the recent progress of direct hydrocarbon SOFC anode materials over the last 15 years. A comprehensive review on liquid hydrocarbon and carbon-free fuels (e.g., ammonia and hydrazine) along with the thermodynamics and kinetics of direct hydrocarbon SOFC was given by Cimenti and Hill.…”
