Recent Trends and Comparison in Fuel Cell Technology (original) (raw)
The fuel cells are an old technology. Problems have plagued their introduction. Present material science may make them a reality soon in specialized applications. The Solid Oxide Fuel Cell appears to be the most promising technology for small electric power plants over 1 kw. The Direct Alcohol Fuel Cell appears to be the most promising as a battery replacement for portable applications such cellular phones and laptop computers. Fuel cells used as electric power plants may be successful before vehicular ones are. This is because a fuel cell produces electric power which is what is required in this case. In transportation applications the electricity produced must then be converted to mechanical power. It is unclear whether hydrogen fuel will be widely used. This is because solid oxide fuel cells will be become extremely popular and these can cleanly convert renewable hydrocarbon fuels. This paper reviews the advances and typical application of fuel cell comparison in terms of parameters like output, application and advantages.
