An Approach To Enhance the CO2 Tolerance of Fluorite–Perovskite Dual-Phase Oxygen-Transporting Membrane

Most of the alkaline earth-containing perovskite-based oxygen-transporting membranes (OTMs) have insufficient tolerance toward CO2 that potentially limits their commercial applications, for example,

Designing CO2-resistant oxygen-selective mixed ionic-electronic conducting membranes: guidelines, recent advances, and forward directions.

This review features the pertaining aspects in addition to the recent status and advances of the two most promising membrane materials, perovskite and fluorite-based dual-phase materials, and explains how to quantify and design CO2 resistant membranes using the Lewis acid-base reaction concept and thermodynamics perspective.

Tailoring Electrocatalytic Properties of Solid Oxide Fuel Cell Composite Cathodes Based on (La0.8Sr0.2)0.95MnO3+δ and Doped Cerias Ce1–xLnxO2–δ (Ln=Gd, La, Er, Pr, Tb and x=0.1–0.2)

Composites made of different doped cerias and (La0.8Sr0.2)0.95MnO3+δ were studied as potential solid oxide fuel cell cathodes. Tb, Pr, Gd and Er have been introduced as ceria dopants to enhance the
