Abstract

To evaluate promising anode, cathode, and separator materials in conditions similar to those present in a full-size water electrolyser, a test cell with electrode area of 10 cm2 was constructed. In order to operate with current densities as high as 1A cm−2 a 10 A pulsed galvanostat was developed and built which features a ‘sample-hold’ circuit to measure the IR-free electrode overvoltages and direct meter readings.
