Present status and future prospects for fuel cell power systems
Article Abstract:
Low environmental impact of fuel-cell power plants and recent worldwide clean-air movements have increased the focus on the development of new types of fuel-cell systems. The phosphoric acid fuel cell (PAFC) is the most advanced type of fuel-cell system, but its cost is a barrier to commercialization of the technology. Improvements in stack performance and the mass production of standard design products should reduce these costs in the future. Market expansion may also help reduce costs, but market expansion usually follows cost reductions, resulting in a vicious cycle that must be broken through cooperation by manufacturers and users. Manufacturers need to demonstrate the stable operation and social reliability of fuel-cell plants. Molten carbonate (MCFC), solid oxide (SOFC) and proton exchange membrane (PEMFC) technologies are showing remarkable progress, but commercialization is not expected until around the turn of the century.

Power electronics - a technology review
Article Abstract:
Power electronics is an important emerging discipline in electrical engineering. Its use is growing in a variety of areas and is gaining special significance in the areas of energy conservation and urban pollution control. Electrical energy demand is increasing as a means of improving our standard of living, but power is generated without due consideration for the impact on the environment. Power electronics helps in reducing both power consumption and environmental impact. Power electronics is expected to impact industrial productivity as well as reducing pollution problems and conserving energy. A review of power electronics technology and current trends is presented.
