摘要：	Over the past thirty-five years, the transportation sector has accounted for approx.25%of the total gross energy consumption in the US. Transportation's share of petroleum use in this time frame has ranged from 50 to 55%. Therefore, the use of fuel cell power plants that could possibly operate more efficiently than internal combustion engines in this type of application has been examined. In addition, these fuel cell power plants can operate on methanol produced from indigenous, non-petroleum sources and thereby reduce US dependency on petroleum resources. Fuel cell power plant use in city buses and automobiles has been explored and feasibility determined from both performance and cost viewpoints. Fuel cell systems for transportation applications have been selected on the basis of state-of-development, performance (both present and projected), and fuel considerations. In the last 25 years, most of the development work by research organizations and industrial firms has focused on five types of fuel cells, classified according to the electrolyte used. In terms of the overall state-of-development of systems, the ranking is as follows: (1) phosphoric acid, (2) alkaline, (3) proton exchange membrane, (4) molten carbonate, and (5) solid oxide.
