英文摘要	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 (<50 mA cm-2) for hydrogen production. In this work, decoupled amphoteric water electrolysis assisted with MnO2/Mn2+ redox mediator demonstrated to separate the stiff couple between hydrogen and oxygen production into two independent processes, which enables hydrogen production to run under high power input (up to 1 A cm-2) with oxygen production under low power input. Furthermore, such an amphoteric decoupled water electrolysis system can be integrated with an Mn-Zn battery, which is able to realize flexible conversion from renewables to hydrogen and electric energy, thus making full use of renewables. © The Royal Society of Chemistry.
