Abstract

Electrochimica Acta.Abstract Platinised titanium mesh is a common electrode material in industrial electrolytic cells and Ce- based redox flow batteries. In this work, the electrodeposition of platinum on a stack of titanium micromeshes is carried out from a flowing alkaline solution in a rectangular channel, divided flow cell.

The active surface area of the electrode was assessed from the charge transfer current for the reduction of Ce(IV) and compared to that of planar and expanded metal mesh electrodes.
