Catalyst improves prospects for fuel cells

Published in Chemistry World, 23 Sep 2010

Chemists in theĀ US have developed a new catalyst that could help in a key reaction used to generate hydrogen for fuel cells.

The so-called water-gas shift (WGS) reaction is often used in industry to help purify the hydrogen that is generated as a by-product in the reforming of natural gas. In the reaction, residual carbon monoxide in the hydrogen is combined with steam in the presence of a catalyst to produce hydrogen and carbon dioxide. The process purifies the hydrogen gas to a level where it can be used in fuel cells. […]
