摘要

It has become commonplace to discuss fuel cells and fuel cell systems in connection with environmental protection and methods to eliminate the consumption of fossil fuels. Many scientists bought into the concept of a hydrogen economy several years ago when the focus was on hydrogen production from renewable sources, with hydrogen promoted as the energy carrier of the future. I have been surprised to see this concept reoriented to the production of hydrogen from fossil fuels, while retaining the advantages set forth by the pioneers for hydrogen from renewable sources. If hydrogen is to be produced from fossil fuel, and used in hydrogen systems then it must stand on it's own merit in efficiency and cost, and compete with fossil fuels on overall environmental and economic impact. For example in large plants, the production of hydrogen from natural gas carries a penalty of about 27%. In other words, only 73% of the energy contained in the fossil fuel is now available for use. This production efficiency and the environmental impact of the facility must be included in the evaluation of the overall hydrogen system.
