The rate of generation of reactive oxygen species (ROS) within the polymer electrolyte membrane (PEM) of an operating proton exchange member fuel cell (PEMFC) was monitored using in situ fluorescence spectroscopy. A modified barrier layer was introduced between the PEM and the electrocatalyst layer to eliminate metal-dye interactions and fluorescence resonance energy transfer (FRET) effects dur...
According to the declining trend of fossil fuel resources and the need to use renewable energies, appropriate research should be conducted for technical and functional studies in this regard. Therefore, in this research, a tubular PEM fuel cell as a suitable energy source with three-dimensional geometry has been numerically simulated and investigated. For a comprehensive study, the equations o...
In this review, we report on the use of low pressure plasmas for elaborating materials at the heart of solid polymer fuel cells (SPFC), especially electrodes and the membrane electrolyte. Electrodes are formed using plasma sputtering techniques while the ion conducting membranes are built up using plasma polymerization. Fuel cell performance will be improved by these approaches. The electrode c...
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 ...
Abstract A mathematical model of the SRM-HTPEM power generation system was developed to simulate effects parameters such as temperature and molar water methanol ratio on performance reformer stack in system. The built at a mobile communication base station, energy efficiency 45.5% an output 2.8 kW. correctness simulation results verified by experiments. It finds that increasing reaction decreas...
