Fabrication of Membrane Electrode Assembly for Micro Fuel Cell by Using Electrophoretic Deposition Process

Abstract

A fabrication of membrane electrode assembly (MEA) was conducted by using an electrophoretic deposition process. In this process, carbon particles and Nafion^® polymer were moved according to the potential gradient and deposited on the Nafion^® membrane with strong adhesion. The polarization curve for the prepared MEA was measured using humidified oxygen and hydrogen at 80°C. The result exhibited that the MEA prepared by the EPD was comparable with that produced by a conventional hot-pressing process.
