Approach for Modulation of the Permselective Properties of Ni(II) Porphyrin Polymers
(Wiley VCH Verlag, 2017-04)
The electropolymerization of Ni(II) Protoporphyrin (polyNiPP) onto glassy carbon electrodes is performed in different experimental conditions, varying the supporting electrolytes, solvent, and oxidative potentials. The AFM ...
Protonic conductivity and thermal properties of cross-linked PVA/TiO2 nanocomposite polymer membranes
(Elsevier, 2019-10-15)
Nanocomposite polymer membranes based on PVA/TiO2 were prepared by a solution casting method. Glutaraldehyde solution (GA) was used as linking agent to improve the chemical, thermal and physical properties of the membranes. ...
Performance of a poly(2,5-benzimidazole)-based polymer electrolyte membrane fuel cell
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
The performance of an ABPBI-based High Temperature H-2/O-2 PEMFC system was studied under different experimental conditions. Increasing the temperature from 130 to 170 degrees C improved the cell performance, even though ...
Improvement on direct ethanol fuel cell performance by using doped-Nafion (R) 117 membranes with Pt and Pt-Ru nanoparticles
(Pergamon-elsevier Science LtdOxfordInglaterra, 2013)
A novel electrocatalyst support with proton conductive properties for polymer electrolyte membrane fuel cell applications
(ELSEVIER SCIENCE BV, 2009)
The objective of this study is to graft the Surface of carbon black, by chemically introducing polymeric chains (Nafion (R) like) with proton-conducting properties. This procedure aims for a better interaction of the ...
