Overcoming Norby gap tradeoff by maintaining high proton conductivity and chemical stability in ceramics at 200–400 °C

"protons become stuck near dopant atoms, overcome using donor co-doping: donor elements molybdenum/ tungsten into barium scandate base (having inherent oxygen vacancies) achieves: proton trapping suppression allowing protons to move freely in 3D, high mobile protons concentration... resulting perovskite-type oxide exhibits superprotonic conductivity of 0.01 S/cm at 193°C/ 0.10 S/cm at 330 °C... chemically stable around CO2, O2, H2... protonic ceramic fuel cells, efficient hydrogen-to-electricity"
