Fuel cells avoid the combustion process and hence are both more efficient and environmentally friendly than the common practice of burning fuels at power plants. Y-doped barium zirconium oxide (BaZrO3) represents one of ...

In order to develop a more efficient cathode oxygen vacancy conduction fuel cell, it is important to understand the oxygen vacancy structure and conduction in perovskites and double perovskites. Previous research using a ...

Proton conduction is a crucial property of fuel cell electrolytes. Unlike oxide-ion conductivity in oxide-ion conductors, proton conductivity occurs at a lower temperature (less than 600◦C), enhancing material stability ...
