Abstract
The authors describe an apparatus for measuring the flow resistance of gas diffusion electrodes which is a mechanical analogon of the Wheatstone bridge for measuring electric resistance. The flow resistance of a circular DSK electrode sheet, consisting of two covering layers and a working layer between them, was measured as a function of the gas pressure. While the pressure first was increased and then decreased, a hysteresis occurred, which is discussed, and explained by a statistical model of a porous electrode.
