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...

As an important energy carrier in terms of carbon neutrality, green hydrogen produced by water electrolysis using renewable electricity has attracted worldwide attention. The polymer electrolyte electrolyzer (PEWE) the potential to be a mainstay market future because its superior performance. However, development PEWE is constrained slow progress membrane electrode assembly (MEA), which essenti...

the reported work is on the preparation and characterization of polyvinyl alcohol -g- polyacrylic acid (pva-g-paa)/ polybenzimidazole sulfone (pbis) cation exchange membrane used for the electro dialysis of sodium chloride solution. the polymer syrup has been prepared using the grafting method with the help of polyvinyl alcohol and polyacrylic acid in the presence of water solvent. the polymer ...

Energy and environmental pollution have become the two major problems in today's society. The development of green energy storage devices with good safety, high reliability, high energy density and low cost are urgently demanded. Here we report on a lithium ion battery using an aqueous electrolyte solution. It is built up by using graphite coated with gel polymer membrane and LISICON as the neg...

A model for the simulation of the steady-state impedance response of a polymer electrolyte membrane fuel cell ~PEMFC! cathode is presented. The catalyst layer of the electrode is assumed to consist of many flooded spherical agglomerate particles surrounded by a small volume fraction of gas pores. Stefan-Maxwell equations are used to describe the multicomponent gas-phase transport occurring in b...

The paper describes an EasyTest cell developed for simple, safe and inexpensive to run testing and optimisation of the active materials (catalysts, catalytic supports, polymer membrane electrolytes) and electrode structures utilized in PEM Fuel cells and Electrolysers. The main advantages of the new EasyTest technique are demonstrated by a comparative study on the performance of two types of me...

The method used to immobilize the polymer on the Disodium ethylenediamine tetraacetate (EDTA) modified carbon paste electrode (CPE/EDTA) has proved its effectiveness for the detection and chelation of heavy metals in aqueous solution. Its complex formation with Pb(II) was examined by square wave voltammetry and cyclic voltammetry. CPE/EDTA electrodes are predisposed to the phenomenon of dissolu...

a highly selective electrode for bromide ion based on aza pyrilium derivative as an excellentionophore is described.the sensor exhibits a good linear response with a slope of ( 60±1 ) mv per decadeover the concentration range of ( 1×10-3 – 9×10-6 m ) , and a detection limit of ( 3×10-6 m ) of bromideions .the electrode response is independent of ph in the range of(4.0 –9.5).selectivity coeffici...
