Degradation Mechanisms of La–Sr–Co–Fe–O[sub 3] SOFC Cathodes

The Superior Properties of La0.6Ba0.4CoO3-δThin Film Electrodes for Oxygen Exchange in Comparison to La0.6Sr0.4CoO3-δ

“…[49][50][51] Especially, the presence of certain atmospheric trace gases such as SO 2 , CO 2 or H 2 O 52-54 as well as Si or Cr sources in the vicinity of perovskite samples in wet atmosphere are known to decrease the electrode performance by formation of Sr rich phases on the surface. 55,56 Even though similar degradation mechanisms may affect thin film electrodes as well as macroscopic electrodes we generally found that degradation rates are faster for thin films.…”

La0.6Sr0.4Co0.2Fe0.8O3 Perovskite: A Stable Anode Catalyst for Direct Methane Solid Oxide Fuel Cells

“…LSCF has found its application as oxygen membrane [1][2][3][4], catalyst for combustion and oxidative coupling of hydrocarbons [5][6][7], and electrocatalyst for redox reactions in solid oxide fuel cells (SOFCs) [8][9][10][11][12]. LSCF as an electrode for SOFC exhibits high mixed electronic-ionic conductivity, high thermal and chemical stability, and also compatibility with other fuel cell materials.…”

Chemical Interaction between Perovskite La0.6Sr0.4FeO3and Super-Ionic Zr0.84Y0.16Ox

“…Some discrepancy in literature data is noted. For example, Simner et al [12][13][14] reported no formation of SrZrO 3 in a LSF20/YSZ system, while in Kindermann et al works [11] this phase is always formed in a LSFM40/YSZ system. Either the amount of strontium or the substitutions for the Fe ion seem to play important role in those interactions.…”

“…[10][11][12][13][14]). Mainly, La 0.8 Sr 0.2 MnO 3 (LSM20) and La 0.8 Sr 0.2 FeO 3 (LSF20), which have relatively low content of Sr ions, were tested.…”
