CO-tolerant electrodes developed with PhosphoMolybdic Acid for Polymer Electrolyte Fuel Cell (PEFCs) application

Development and characterization of chitosan and phosphomolybdic acid (PMA) based composites

“…This shows the semi crystalline nature of chitosan. From the diffractograms of PMA it can be observed that it shows sharp crystalline peaks between 10° 2 to 45° 2 , which indicates the purely crystalline behavior of PMA [18]. The basal spacing (d 001 ) from ) at peak positions.…”

Electrochemical behavior and its electrocatalytic properties of chemically modified electrode with Keggin-type [SiNi(H2O)W11O39]6−

“…Recently, the considerable interests have been focused on polyoxometalates (POMs) clusters not only due to their special intrinsic structure but also due to their potential application in the field of material science, catalysis, biology and medicine [1][2][3][4][5]. Transition metal substituted POMs, as a class of structurally well-defined anionic clusters with an enormous disparity in size, composition, and function, have attracted much attention [6,7].…”

An electro-kinetic study of oxygen reduction in polymer electrolyte fuel cells at intermediate temperatures

“…The electrodes were prepared by a spray technique as described elsewhere [38,39]. In particular, the catalytic layer was obtained by mixing the electro-catalysts previously prepared, (30% Pt/C for anode and 50 wt % PteCo/C for cathode), with a 33% (wt/wt) Nafion alcoholic solution (Aldrich, 5% wt/wt), 20% (wt/wt) of ammonium carbonate (Carlo Erba) as a pore-former.…”
