摘要

Deregulation of the electric power industry and more stringent emission controls are stimulating investment into fuel-cell systems, which are virtually free from noxious emissions of nitrogen oxides normally associated with burning fossil fuels. They can convert chemical energy directly into electricity with greater efficiency than most other devices, which both conserves fuel resources and reduces CO_2 emissions. Although hydrogen is considered the ideal fuel for many energy-conversion systems, its widespread use is dependent on technological breakthroughs in its cost and storage. So it is best to assume that in the immediate future, except for a few niche markets, fuel cells will have to use hydrocarbons (such as methane) or alcohols (such as methanol) as fuel. In this context, it is timely to examine the merits of direct electrochemical oxidation of methane in a fuel cell reported by Murray et al. on page 649 of this issue.
