The conductivity of proton-conducting perovskites is limited by the absence of intrinsic protons. Here, the authors introduce a synthesis method to incorporate protons into Al-doped ceria (AlxCe1-xO2-δ, x = 0.2) that relies on photo-activated radical reactions, producing a protonated conducting oxide with 922 mW cm-2 power density at 500 °C.
