BaTb_0.3Fe_0.7O_3−δ: a new proton-conductor-derived cathode for proton-conducting solid oxide fuel cells

Abstract

BaTbO3 is a much less focused proton-conductor than the traditional BaCeO3-BaZrO3 system due to its lower proton conductivity. However, the present study reveals that using BaTbO3 as the parent material...

Method to determine the oxygen reduction reaction kinetics via porous dual-phase composites based on electrical conductivity relaxation

“…† The excellent match demonstrated the good reliability of the DCT model. Compared with the common method of a single characteristic time (1 − exp(t/s)), 53 which is normally applied for dense samples whose transport process is limited by surface exchange, the DCT model gave much better results, i.e., an improved matching with the experimental data and a reduced standard deviation, Fig. S6.…”

Successful preparation of BaCo 0.5Fe 0.5O 3– δ cathode oxide by rapidly cooling allowing for high-performance proton-conducting solid oxide fuel cells

“…It should be mentioned that the performance of the BCF cell is superior to the performance of the BSCF cell in this study and also larger than most of the H-SOFCs reported in Refs. [11,17,[45][46][47][48][49][50][51][52][53][54][55][56][57][58]. The chemical compatibility examination between BCF and BZY is carried out, and the result is shown in Fig.…”
