Abstract
- A series of W doped Pr 0.5 Ba 0.5 (Co 0.7 Fe 0.3)O 3-δ (PBCF) are prepared and characterized as cathodes for proton-conducting solid oxide fuel cell (H–SOFC). The enhancement of proton migration and formation ability through W doping significantly increases the cell performance and it is further verified by the density functional theory (DFT) simulation, presenting the high valence element doping can be a potential approach for the design of cathode. • W doped PBCF at proper concentration can form Single and double perovskite composites. • The performance of H-SOECs is highly improved by applying this novel element. • Proton migration and transportation energies are calculated using DFT method.
