The La+3-, Nd+3-, Bi+3-Doped Ceria as Mixed Conductor Materials for Conventional and Single-Component Solid Oxide Fuel Cells

Clean energy devices are essential in today’s environment to combat climate change and work towards sustainable development. In this paper, the potential materials A2Ce2O7−δ (A = La+3, Nd+3, Bi+3) were analyzed for clean devices, specifically conventional single-component solid oxide fuel cells (SC-SOFCs). The wet chemical route has been followed preparation of samples. X-ray diffraction patterns showed that all three samples exhibited a defected fluorite cubic structure. It also revealed presence dopants ceria, which was confirmed by fingerprint region FTIR. optical behavior, cell performance electrochemical behavior studied UV–vis, testing apparatus EIS, respectively. SEM results had irregular polygons. Raman spectra, F2g mode corresponding space group (Fm3m) confirms spectra have different trends. maximum power density Bi2Ce2O7 0.65 Wcm−2 at 600 °C. La3+, Nd3+, Bi3+) as Nd2Ce2O7−δ is best choice with semiconductors conductors ZnO NCAL. highest (Pmax) Nd2Ce2O7/ZnO 0.58 Wcm−2, while output Nd2Ce2O7/NCAL 0.348 650 All good agreement compared NCAL SC-SOFCs.
