Achieving performance and longevity with butane-operated low-temperature solid oxide fuel cells using low-cost Cu and CeO₂ catalysts

Abstract

Thin-film solid oxide fuel cells (TF-SOFCs) effectively lower the operating temperature of typical solid oxide fuel cells (SOFCs) below 600 °C, while maintaining high efficiency and using low-cost catalyst. But...

A comprehensive investigation of direct ammonia-fueled thin-film solid-oxide fuel cells: Performance, limitation, and prospects

“…The Bode plot in Figure 3 B shows that the impedance increased in the low-frequency range (10 0 to 10 2 Hz). Low-frequency impedance is generally attributed to gas diffusion of reactants ( Gasper et al., 2020 ; Jeanmonod et al., 2020 ; Miyazaki et al., 2020 ; Thieu et al., 2022 ). Adding hydrogen gas to the ammonia fuel slightly decreased the low-frequency impedance.…”

“…Nanostructure incorporation of both the anode and cathode with reduced electrolyte thickness improved the performance of low-temperature SOFCs ( Bae et al., 2017 ; Chao et al., 2011 ; Karimaghaloo et al., 2019 ; Kim et al., 2011 ; Myung et al., 2011 ; Thieu et al., 2017 ). The performances of our TF-SOFCs using hydrogen and butane fuels are among the best reported under ≤650°C ( Park et al., 2021 ; Thieu et al., 2020 , 2022 ). The coupling of TF-SOFCs with ammonia fuel is an excellent combination for low-temperature DA-SOFCs.…”

Hydrogenated ceria nanoparticles for high-efficiency silicate adsorption

“…Given that their versatile characteristics based on high oxygen storage capacity (OSC) and low redox potential, ceria (CeO 2 ) nanoparticles (NPs) have garnered considerable interest in various fields for applications including solid oxide fuel cells, [1][2][3] UV shielding, 4 gas sensors, 5,6 biomedicine [7][8][9] and chemical mechanical planarization (CMP). [10][11][12][13] The unique properties of CeO 2 are attributed to their low vacancy defect formation energy, which causes oxygen vacancies on the surface of CeO 2 NPs.…”
