Tailoring cobalt‐free La <sub>0.5</sub> Sr <sub>0.5</sub> FeO <sub>3‐δ</sub> cathode with a nonmetal cation‐doping strategy for high‐performance proton‐conducting solid oxide fuel cells
نویسندگان
چکیده
A nonmetal doping strategy was exploited for the conventional La0.5Sr0.5FeO3-δ (LSF) cathode, allowing high performance proton-conducting solid oxide fuel cells (H-SOFCs). Unlike previous studies focusing on utilization of metal oxides as dopants, phosphorus, which is a element, used cation dopant LSF by partially replacing Fe ions to form new La0.5Sr0.5Fe0.9P0.1O3-δ (LSFP) compound. The H-SOFC using LSFP cathode showed two-fold peak power density compared that cathode. Both experimental and first-principle calculations were unveil mechanisms cells.

Solid oxide fuel cells (SOFC) are the cleanest, most efficient, and cost-effective option for direct conversion to electricity of a wide variety of fuels. While significant progress has been made in anode materials with enhanced tolerance to coking and contaminant poisoning, cathodic polarization still contributes considerably to energy loss, more so at lower operating temperatures. Here we rep...

Nanoionics has become increasingly important in devices and systems related to energy conversion and storage. Nevertheless, nanoionics and nanostructured electrodes development has been challenging for solid oxide fuel cells (SOFCs) owing to many reasons including poor stability of the nanocrystals during fabrication of SOFCs at elevated temperatures. In this study, a conformal mesoporous ZrO2 ...
