Components for PEM fuel cell systems using hydrogen and CO containing fuels
TL;DR: In this article, the use of improved electrocatalysts for the anode, such as PtRu alloys, can significantly enhance the CO tolerance and prevent CO poisoning of anode.

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.

A Study of Capillary Porous Structure and Sorption Properties of Nafion Proton‐Exchange Membranes Swollen in Water
TL;DR: In this paper, the porosimetry method was used to study capillary porous and sorption properties of Nafion proton exchange membranes, and the charge density at the inner pore surfaces was evaluated.

Performance Modeling of a Direct Methanol Fuel Cell
TL;DR: In this paper, a two-dimensional model of a direct methanol fuel cell (DMFC) has been developed and numerically tested, which regards the diffusion layers as water-gas systems in the pore space with saturation and permeability varying according to capillary effects.

Two‐Dimensional Simulation of Direct Methanol Fuel Cell. A New (Embedded) Type of Current Collector
TL;DR: In this paper, a two-dimensional numerical model of the direct methanol fuel cell with gas fuel is developed and a new design of current collectors is suggested based on the simulation results.
