Abstract

Water transport induced by heat flow across polymer electrolyte fuel cell (PEFC) membranes has been studied under wellcontrolled thermal conditions. The investigation showed that water can be transferred across a membrane electrode assembly (MEA) that is subjected to a through-plane temperature differential. Thermo-osmotic water transport is a membrane-controlled phenomenon. The thermally driven water flux was found to be relatively large even for small temperature differences (∼1°C). A physical model of thermo-osmosis is proposed. Comparison between the proposed model results and the experimental data shows good agreement. copyright The Electrochemical Society.
