    Notes: Abstract A novel chemically regenerative redox fuel cell is described. The electrode reactions are based on the following redox reactions: cathodic reaction: anodic reaction: VO 2 + +2H++e → VO2++H2O (E 0 ∼+1V), SiW12O 40 5− → SiW12O 40 4− +e (E 0∼ 0V). Regeneration of the oxidant by direct oxidation with O2 was achieved by using the soluble heteropoly acid catalysts, H3PMo12O40 or H5PMo10V2O40, whereas regeneration of the tungstosilicic acid, H3SiW12O40, was accomplished by direct reduction with H2 utilizing small amounts of Pt, Pd, Rh, Ru or the soluble Pd-4, 4′, 4″, 4″'-tetrasulphophthalocyanine complex as catalysts. Some aspects of the regeneration kinetics and their influence on the overall performance of the redox fuel cell are discussed.

    Notes: Abstract Our previous paper [1] has described an unconventional chemically regenerative redox fuel cell, including a modest amount of performance data, and has pointed out a number of problem areas. This paper describes additional work and some attempts that have been made to improve the cell performance in several of the problem areas described in the first paper. Two different redox fuel cell systems employing the V2+/V3+ and Mo3+Mo4+ redox couples as the anolyte, and a new NO 3 −/NO catalyst system for VO2+ oxidation were explored and described. The reduction of Na2MoO4 to Mo4+ and Mo3+ by H2 in concentrated H2SO4 solution was studied in small scale laboratory experiments and discussed. The performance of a redox cell in which H2 was obtained from the Pd-catalysed decomposition of formic acid, HCOOH, is described and the results of experiments with different membranes are reported. The results of experiments using WC as a hydrogenation catalyst at a temperature of 70–90° C with mixed molybdo-tungsto-silicic acids are reported and discussed.

    High power density performance of WPt and WRh electrodes in the alkali metal thermoelectric converter (1989)
    In:  Other Sources
    Details
    Publication Date: 2011-08-19
    Description: The properties of the alkali metal thermoelectric converter (AMTEC) are discussed together with those of an efficient AMTEC electrode. Three groups of electrodes were prepared and tested for their performance as AMTEC electrodes, including WPt-T3, WRh-B1, and WRh-B2. The best electrodes of both WPt and WRh types typically exhibited low porosity, and thickness greater than 0.8 micron, which indicated that transport in these electrodes does not occur by a purely free-molecular flow mode. The observed values of the exchange current were found to be within the range of those observed for oxide-free Mo electrodes under similar conditions.
