Performance of a metallic gas diffusion layer for PEM fuel cells
A novel metallic porous medium with improved thermal and electrical conductivities and controllable porosity was developed based on micro/nano echnology for its potential application in PEM fuel cells. In this work to demonstrate its applicability, the gas diffusion medium, made of 12.5 m hick copper foil, was tested in an operational fuel cell. The small thickness and straight-pore feature of ...
متن کاملDevelopment of Novel Gas Diffusion Layer for Fuel Cells with Micro/Nano Technology
A new fabrication technique is employed to convert a metallic foil into a porous structure with an array of micron size pores. The motivation stems from the need to develop a more efficient and controllable gas diffusion medium for fuel cell applications. The influence of mask shape, mask width and etching time was investigated experimentally. A correlation to predict trench width with etching ...

متن کاملImpact of anisotropy level of gas diffusion layer on the temperature distribution of a PEM fuel cell cathode electrode
Proton exchange membrane (PEM) fuel cells being employed in fuel cell vehicles (FCVs) are promising power generators producing electric power from fuel stream via porous electrodes. Structure of carbon paper gas diffusion layers (GDLs) applying in the porous electrodes can have a great influence on the PEM fuel cell performance and distribution of temperature, especially at the cathode side whe...
متن کاملOxygen Reduction on Gas-Diffusion Electrodes for Phosphoric Acid Fuel Cells by a Potential Decay Method
The reduction of gaseous oxygen on carbon-supported plat inum electrodes has been studied at 150~ with polarization and potential decay measurements. The electrolyte was either 100 weight percent phosphoric acid or that acid with a fluorinated additive, potassium perfluorohexanesulfonate (C6FI3SO3K). The pseudo-Tafel curves of the overpotential vs. log (iiL/(iL -i)) show a two-slope behavior, p...
