Abstract

Novel diffusion layers for liquid direct methanol fuel cells (DMFCs) are designed and fabricated. The factors affecting the performance of DMFCs are determined. The results demonstrate that the diffusion layers made by micrometer scale particles and a hydrophilic binder can reduce the liquid sealing effect and increase the mass transfer property. The performance of DMFCs made using novel diffusion layers is greatly improved. The porous structure of such diffusion layers may improve the channels therein, which allows liquid methanol to diffuse in and gaseous CO~2~ to diffuse out easily. Higher methanol concentrations can be used due to the formation of a larger three‐phase interfacial area.

## Abstract The influence of ionomer content on the performance of direct methanol fuel cells (DMFC) is studied. The performance is studied as a function of the (nafion/carbon, N/C) ratio on the anode and cathode. The performance of the DMFC has been found to increase as a function of the N/C ratio

Pinholes in the membrane electrode assembly (MEA) of a fuel cell can lead to premature fuel cell failure. The main causes for pinhole formation are contaminant particles, non-uniform stress distribution, and membrane corrosion. In this paper fuel cell performance is compared before and after piercin

A kinetic model for the anode processes in low temperature proton exchange membrane fuel cells with a Pt based anode is developed. The model is as simple as possible with the minimum number of parameters, and most are determined directly from density functional calculations of adsorption energies. I
