CATALYTIC ENHANCEMENT OF CARBON MONOXIDE AND REFORMER GAS OXIDATION IN FUEL CELLS BY SODIUM TUNGSTEN BRONZES

Abstract

Relatively high surface area sodium tungsten bronzes (4 to 6 sq m/g) have been prepared; these materials serve as promoters for catalytic oxidation of carbon monoxide and reformer gas in fuel cells much same as tungsten oxides; effectiveness of bronze promoters increases with increasing sodium content.
