Low Temperature Formation of Hydrogen from CO + H ₂ O

Hydrogen is one of the better fuels for use in fuel cells. In the production of hydrogen by reacting hydrocarbons with steam, large quantities of CO must be converted to hydrogen by the classical water-gas shift reaction. Newer catalysts operating at low temperatures offer certain advantages over “conventional” catalysts. Several applications, are discussed, illustrating the advantages of the low-temperature CO conversion catalyst (400 F and higher).
