This paper reports the development of a fuel cell consisting of a vanadium flow battery in which the vanadium ions are reduced by sugar (from a carbohydrate) to oxidation state +3 on one side of a membrane, and are oxidized to state +5 on the other s

Platinum and other nobel metals have been found to catalyze the complete oxidation of sucrose and other sugars by vanadium(IV) in acid environments. As the redox potential of vanadium(IV)/vanadium(III) differs substantially from that of dioxygen/wate

Linear relationships between the core electron binding energies and atomic charges previously derived in our laboratory have been tested on XPS data for Cu 2 O, CuO, Cu(NO 3 ) 2 and CuFeS 2 , as well as for CuF 2 and CuCl 2 . Atomic charges are obtai

The kinetics of the reduction of TiO2+ with H2 has been studied using a platinum catalyst in hydrochloric acid medium. The kinetic results were used to design the performance of a chemically regenerative redox fuel cell with the Ti3+/TiO2+ redox coup

A method for internal calibration of ESCA (XPS ) spectra is described that permits the use of a simple relation between binding energy ( E b ) and atomic charge ( q ) : E b = kq + E b0 . This relation has been shown to hold for a large number of elem

Three different types of membrane have been tested in a chemically regenerative redox fuel cell. It was found that a Nafion membrane gave the best polarization curves, but also that a much cheaper silica-filled polyethylene membrane could be used. A

IR intensity and ESCA measurements have been used to determine the distribution of atomic charges in the bis (triphenylphosphoranylidene) ammonium ion. The central nitrogen atom has a charge of -0.5 whereas the two phosphorous atoms have positive cha
