In this work nonstoichiometric strontium cerium manganites and cobaltites Sr 0.8 Ce 0.1 Ln 0.1 MnO 3−δ and Sr 0.9 Ce 0.05 Ln 0.05 CoO 3−δ with low content of various lanthanides (Ln=La, Ce, Nd, Sm, Gd, Dy, Yb) were investigated as potential electrode materials for solid state fuel cells and gas sensors. Synthesis and sintering conditions...
W pracy badano mo żliwość zastosowania grubowarstwowych perowskitowych elektrod wykonanych z Sr0.8Ce0.1La0.1MnO3-δ Sr0.9Ce0.05La0.05CoO3-δ na elektrolitach stałych z domieszkowanego tlenku cyrkonu i tenku ceru, w oparciu o obserwacje w mikroskopie skaningowym, badania metodą spektroskopii impedancyjnej i pomiary siły elektromotorycznej stężeniowych ogniw tlenowych. Analiza pomiarów zespolonej impedancji,...
