Summary: The perovskite NdSrCo2O5+delta (NSCO) shows high electrical conductivity and is used as the cathode material for Ce0.8Gd0.2O2-delta (GDC)-supported microtubular solid oxide fuel cells (MT-SOFCs). By varying design parameters, the MT-SOFC with an outer tube diameter of 1.86 mm, an electrolyte thickness of 180 um, and a 5NSCO-5GDC composite cathode exhibits the best performance, with high power density and mechanical integrity. The results demonstrate the high electrochemical activity of the NSCO-GDC composite and exceed existing MT-SOFCs in terms of power density.

Summary: To address the stability issue of La0.6Sr0.4Co0.2Fe0.8O3-delta (LSCF) cathode, researchers propose a novel approach of introducing La(0.9)5CoO(3-delta) (LC95) thin film onto the surface of the porous LSCF scaffold. The hybrid cathode (LSCF@LC95) shows lower polarization resistance and remarkable long-term stability compared to the pristine LSCF cathode.

Summary: This study investigates the effects of Mg doping on the performance of Mn-Cr spinel oxide cathodes in solid oxide fuel cells (SOFCs). Both experimental results and density functional theory (DFT) calculations show that Mg doping can optimize the electronic structure of the spinel oxide, increase the oxygen vacancy concentration, and improve the electrical conductivity and catalytic activity. The Mg-doped Mn-Cr spinel oxide cathode exhibits superior performance with high area-specific polarization resistance and maximum power density.

Summary: This article reviews different techniques for the removal of pollutants from diesel exhaust gasses using an all-solid-state electrochemical reactor, comparing the advantages and drawbacks of different concepts. Early research focused on removing either hydrocarbons or NOx, with high current consumption, while more recent research has shown potential for removing all pollutants with one type of electrochemical reactor, although power consumption remains a challenge.
