TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Method: A gas comprising carbon monoxide and hydrogen is reacted with the solution of oxidized POM. The oxidation of carbon monoxide to carbon dioxide yields a product gas comprising hydrogen and a depleted amount of carbon monoxide. The product gas is oxidized in a fuel call to generate energy. The carbon monoxide is reacted with an aqueous solution comprising an oxidized POM. The carbon monoxide is reacted within the oxidized POM at not greater than 300oK.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Compounds: The oxidized POM has a Keggin structure. It may be of formula (I) or (II).(Y3-18)n+ (X1-4M1-36O10-60)n- (I)(Y3-18)n+ (M1-36O10-60)n- (II)X = element or molecular moiety having less than or equal to4 atoms (preferably P, Si, As, Ge, B, Co, S, or Fe);M = metal (preferably W, V, Ti, Co, Cu, Zn, Fe, Ni, Cr, lanthanide, Ce, Al, Ga, In, or Tl);Y = counter-ion (preferably H, Zn, Co, Cu, Bi, Na, Li, K, Rb, Cs, Ba, Mg, Sr, ammonium, or 1-12C alkylammonium or alkylamine); andn = integer.It may also be of formula (III).(Yy)n+ )(XM12O40)n- (III)X = Si, P or Ge;M = Mo, W or V;Y = H, Zn, Co, Cu, Bi, Na, Li, K, Rb, Cs, Ba, Mg, Sr, ammonium, and/or 1-12C alkylammonium or alkylamine; andn, y = integers.Preferably, it may be oxidized H3PMO12O40.    TECHNOLOGY FOCUS - METALLURGY - Preferred Materials: The metal-containing catalyst is transition metal-containing catalyst or inner transition metal-containing catalyst. It may be a Group VIIIB metal-containing catalyst or Group IB metal-containing catalyst. It may be a noble metal-containing catalyst, preferably a gold-containing catalyst. The metal-containing catalyst is a nanotube and/or a nanoparticle. It may be immobilized on a substrate, within pores of the substrate, or on a track-etched template. The anode and the cathode of the fuel cell are fabricated from gold, silver, platinum, or carbon. They may also be devoid of precious metals.    TECHNOLOGY FOCUS - POLYMERS - Preferred Material: The template comprises polycarbonate.
