Membranes are a critical component in flowing-electrolyte electrochemical systems like
redox flow batteries (RFB), and as such, they contribute significantly to overall RFB stack
cost which affects technology adoption. We explore flow-field-informed membrane coverage
distribution in this part of the series. Where membrane coverage distribution is specifically
informed by the relative positions of the 'channel'and 'land'in the adopted flow-field design–
towards cell/stack cost reduction with minimal compromise in power and efficiency …

The high costs of the currently used membranes in vanadium redox flow batteries (VRFBs)
contribute to the price of the vanadium redox flow battery systems and therefore limit the
market share of the VRFBs. Here we report a detailed simulation and experimental studies
on the effect of membrane reduction of single-cell VRFB. Different simulated designs
demonstrate that a proposed centred and double-strip membrane coverage showed a
promising performance. Experimental charge-discharge profile of different membrane size …
