PHM of Proton-Exchange Membrane Fuel Cells - A review

Chemical Engineering Transactions, 2013
Fuel Cell (FC) systems are promising power-generation sources that are more and more presented as a good alternative to current energy converters such as internal combustion engines. They suffer however from insufficient durability for stationary and transport applications, and lifetime may be improved.

Synergistic Interplay of Acceptor and Isovalent Co‐Doping on BaZrO3‐Based Proton Conducting Oxides: A First‐Principles Study

Advanced Science, EarlyView.
Acceptor and isovalent co‐doping effects on hydration in BaZrO3 proton conductors are systematically investigated using first‐principles calculations. Acceptors enhance hydration by modulating oxygen vacancy formation, whereas isovalent dopants enhance hydration by stabilizing protons via increased A‐site cation–proton distances.
