*Headline*: Solving the Problems of Proton-Conducting Perovskites for
Next-Generation Fuel Cells
* Body: **As a newly developed perovskite with a large amount of intrinsic
oxygen vacancies, BaSc0.8W0.2O2.8 achieves high proton conduction at low
and intermediate temperatures, report scientists at Tokyo Tech. By the
donor doping of large W6+, this material can take up more water to increase
its proton concentration, as well as reduce the proton trapping through
electrostatic repulsion between the dopant and proton. These findings could
pave the way to the rational design of novel perovskites for protonic
ceramic fuel cells (PCFCs) and electrolysis cells (PCECs).*
