BATTERIES - RMIT researchers develop concept “proton flow battery”

RMIT University (Australia) researchers have developed a concept battery based on storing protons produced by splitting water—a reversible fuel cell with integrated solid proton storage electrode. As only an inflow of water is needed in the charge mode, and air in discharge mode, the system is called a “proton flow battery”. This new concept has the potential to increase roundtrip efficiency compared to the conventional hydrogen-based electrical ...
