New high proton conductors with inherently oxygen deficient layers open sustainable future

Over the past few years, fuel cells have become a focal point of research in eco-friendly technology because of their superior abilities to store and produce renewable energy and clean fuel. A typical type of fuel cell gaining ground is the proton-conducting fuel cell, which is primarily made of materials through which hydrogen ions (protons: H+), can easily move. Proton-conducting materials provide a number of advantages over commonly used fuel cells that comprise oxide-ion conductors for electrolytes, such as higher conductivity at low and intermediate temperatures, longer lifetimes, and lower costs.
