Research emphasized 1 the search for non-noble catalysts, 2 the development of non-corrosive intermediate temperature electrolytes and 3 studies to improve noble metal utilization. Freeze drying can be an effective method for producing conductive high surface area metal tungsten oxides catalysts but these materials did not show any increased activity. Raney nickel- cobalt alloy catalysts have demonstrated electrochemical activity on butane in the 250 C phosphate melt electrolyte. This appears to be the first case of saturated hydrocarbon activity with a non-noble catalyst system in a CO2- rejecting electrolyte. Supported platinum catalysts continue to show promise of significant activity improvement in both low and intermediate temperature cells.
