M Hamer, Can bio-booze fuel the hydrogen economy?, NewScientist, 21 February 2004, p 23

In US, the University of Minnesota has developed a compact reactor to transform ethanol, water and air into hydrogen and carbon dioxide. The fuel-air mix is injected into the 10 cm long reactor, and vaporised at 140 ºC, the gases then passing over a rhodium and cerium oxide catalyst to produce hydrogen, carbon monoxide and carbon dioxide at 700 ºC. These gases pass to a chamber where they cool to 400 ºC and make contact with a platinum and cesium oxide catalyst where CO and water react to equal quantities of H2 and CO2. The initial ethanol could be derived from vegetable crops.
