Decoupled amphoteric water electrolysis and its integration with Mn-Zn battery for flexible utilization of renewables

Amphoteric water electrolysis with a bipolar membrane can accommodate optimal pH conditions simultaneously for both cathode and anode under steady-state operation without changing the overall thermodynamics of water splitting. However, the high voltage loss of bipolar membrane imposes significant co...

Zusammenfassung:Amphoteric water electrolysis with a bipolar membrane can accommodate optimal pH conditions simultaneously for both cathode and anode under steady-state operation without changing the overall thermodynamics of water splitting. However, the high voltage loss of bipolar membrane imposes significant constraints on operating current density, leading to low current density (
