A very active cathode material for intermediate temperature - solid oxide fuel cells (IT-SOFCs) is obtained by mixing La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3-δ (LSCF) and Ba 0.5 Sr 0.5 Co 0.8 Fe 0.2 O 3-δ (BSCF) powders. Three different volume ratios are considered: BSCF-LSCF 50-50 v/v% (BL50), BSCF-LSCF 70-30 v/v% (BL70) and 30–70 v/v% (BL30). The...

Mixture of La0.6Sr0.4Co0.2Fe0.8O3-δ and Ba0.5Sr0.5Co0.8Fe0.2O3-δ, was investigated as promising cathode for intermediate temperature solid oxide fuel cells (IT-SOFCs). The two perovskites possess high catalytic activity for the oxygen reduction (ORR), although some problems related to their chemical and structural stability have still to be...

A high temperature structural study (673–1073 K) was performed by means of synchrotron x-ray diffraction and μ-Raman spectroscopy on several compositions belonging to the Ce1−xSmxO2−x/2system with the aim to investigate the crystallographic features of Sm-doped ceria electrolytes at the fuel cell operating temperatures; ionic conductivity of...

This work presents results of a measurement setup which was constructed for understanding the performance contributions of the individual compartments and reactions taking place in the patented concept of IDEAL-Cell (described in detail in (1)). By inserting a third measurement point at the central membrane of an ideal cell, it was possible to...
