Photo-assisted synthesis of protonated oxides for fuel cells
Abstract The absence of intrinsic protons in proton-conducting oxides (PCO) is a significant challenge that limits the proton conductivity of proton-conducting perovskites, such as Y-doped BaMO3 (M = Zr, Ce), in proton ceramic fuel cells exhibit low conductivity (10-3 to 10-2 S cm-1 at 600 °C).

| description | Abstract The absence of intrinsic protons in proton-conducting oxides (PCO) is a significant challenge that limits the proton conductivity of proton-conducting perovskites, such as Y-doped BaMO3 (M = Zr, Ce), in proton ceramic fuel cells exhibit low conductivity (10-3 to 10-2 S cm-1 at 600 °C). Herein, we introduce a photo-assisted synthesis method for incorporating protons into Al-doped ceria (AlxCe1-xO2-δ, x = 0.2; M-ACO), leveraging the open cubic fluorite structure and photo-activated radical reactions. Specifically, photon-generated hydroxyl reactive $$\left({{{\rm{OH}}}}^{{{\bullet }}}\right)$$ OH ∙ and superoxide ( $${{{\rm{O}}}}_{2}^{{{\bullet }}-}$$ O 2 ∙ − ) Radicals are generated and interact with the ACO crystal lattice, facilitating proton incorporation and resulting in the synthesis of native-proton-type PCO. This process results in a protonated (H-ACO) with a high proton conductivity of 0.14 S cm-1 and exceptional power density of 922 mW cm-2 at 500 °C. This versatile synthesis methodology offers broader development of advanced PCO for energy-related applications. |
