computational fluid dynamics analysis was employed to investigate the radial flow field patterns of proton exchange membrane fuel cells (pemfc) with different channel geometries at high operating current densities. 3d, non-isothermal was used with single straight channel geometry. our study showed that new generation of fuel cells with circle stack with the same active area and inlet area gave ...

modeling the heat and mass transport in micro channel is being used extensively in researches and industrial applications. the aim is optimizing fuel cell designs before building a prototype for engineering application. in this study, numerical, three-dimensional, single phase computational fluid dynamics model of a proton exchange membrane fuel cell with both the gas distribution flow channels...

Front Cover: In article number 2100238 by Dario R. Dekel, Charles E. Diesendruck and co-workers look at the ligand valency effect on alkaline stability of metallopolymer anion-exchange membranes. fuel cells electrolyzers, aggressive environment decomposes organic cations metallopolymers present a promising alternative. ROMP polynorbornenes with multidentate pyridine-Nickel complexes are used to...

In this work, the metal content of Pd85Ni10Bi5/C catalysts for alkaline ethanol-oxidation reaction was reduced from 40 wt.% (PdNiBi/C (40/60)) to 30 (30/70)), 20 (20/80)) and 10 (10/90)), while increasing performance. The synthesized were examined using physicochemical measurements electrochemical measurements. best performing used fabricate membrane electrode assemblies carrying out single-cel...
