Abstract

Here, we report on a low cost and novel architecture Direct Methanol Fuel Cell (DMFC) for mobility and portable applications. DMFC is fast charged by a low cost liquid fuel, thus it is expected to be competitive with the hydrogen gas fuel cells. Our research efforts have culminated in the outstanding performance of DMFC with very high power density of 181 mW cm−2 at 80 °C, under very low air pressure of 0.05atm. This exceptional DMFC performance was achieved by a modification of the hydrophobicity of the BPP (Bi-Polar Plate) flow field channels. Our study of the effects of the hydrophobicity of bipolar flow field plates give rise to fundamental understanding of the relationship between the two-phase flow, that occurs in the flow channels of the bipolar plates of DMFC cells. To the best of our knowledge, such performance was never achieved prior to this work.
