Abstract

A single-channel DMFC is constructed that allows for flow measurements at the anode side as well as detailed time–resolved cell-voltage measurement. The coherence between flow and bubble clogging and slug movement can be investigated without parasitic effects like flow shortcuts through the gas diff...
