A Methanol-Tolerant Carbon-Supported Pt−Au Alloy Cathode Catalyst for Direct Methanol Fuel Cells and Its Evaluation by DFT
G. Selvarani,S. Vinod Selvaganesh,S. Krishnamurthy,G. V. M. Kiruthika,Parthasarathi Sridhar,S. Pitchumani,Ashok Kumar Shukla +6 more
TL;DR: In this article, a carbon-supported Pt-Au alloy was used as the cathode catalyst in a direct methanol fuel cell (DMFC) to achieve a peak power density of 120 mW/cm2 at 70 °C.
Journal ArticleDOI
Nafion and modified-Nafion membranes for polymer electrolyte fuel cells: An overview
TL;DR: In this paper, the authors present an overview on Nafion membranes highlighting their merits and demerits with efforts on modified-Nafion membrane, which is a key component of PEFC and its performance is controlled by several physical parameters, viz. water up-take, ion exchange capacity, proton conductivity and humidity.
Journal ArticleDOI
Cross-linked polymer hydrogel electrolytes for electrochemical capacitors
TL;DR: In this paper, acid polyvinyl alcohol/polyacrylic acid blend hydrogel electrolytes (BHEs) were prepared by cross-linking with glutaraldehyde and perchloric acid.
Journal ArticleDOI
A new mixed-matrix membrane for DMFCs
S. Mohanapriya,Santoshkumar D. Bhat,Akhila Kumar Sahu,S. Pitchumani,Parthasarathi Sridhar,Ashok Kumar Shukla +5 more
TL;DR: In this paper, a mixed-matrix membrane based on stabilized phosphotungstic acid (PTA) incorporated to chitosan (CS)-hydroxy ethyl cellulose (HEC) for application in direct methanol fuel cells (DMFCs) is reported.
Journal ArticleDOI
Sodium-alginate-based proton-exchange membranes as electrolytes for DMFCs
S Mohanapriya,Santoshkumar D. Bhat,Akhila Kumar Sahu,A. Manokaran,R Vijayakumar,S. Pitchumani,Parthasarathi Sridhar,Ashok Kumar Shukla +7 more
TL;DR: In this paper, mixed-matrix membranes prepared by blending NaAlginate (NaAlg) with polyvinyl alcohol (PVA) and certain heteropolyacids (HPAs), such as phosphomolybdic acid (PMoA), phosphotungstic acid (PWA), followed by ex-situ cross-linking with glutaraldehyde (GA) to achieve the desired mechanical and chemical stability, are reported for use as electrolytes in direct methanol fuel cells (DMFCs).
