Recent developments of the measurement of the methanol permeation in a direct methanol fuel cell
TL;DR: In this article, the authors showed that with low methanol concentrations and high current densities, the amount of carbon dioxide passing from the anode to the cathode can even be higher than the amount formed at the cathodes by methanoline oxidation.

DMFC employing a porous plate for an efficient operation at high methanol concentrations
TL;DR: In this paper, the effect of employing a porous carbon plate on the performance of a passive direct methanol fuel cell (DMFC) under closed circuit conditions was investigated, and it was confirmed that the Faraday efficiency remained high, and the back diffusion of water from the cathode to the anode through the membrane occurred, contrary to the case without the porous plate.
