Abstract
Fuel Cell is an environment friendly generation device. Among several kind of fuel cell types. PAFC (Phosphoric Acid Fuel Cell) is the most developed one, and its wide penetration to the commercial market can be expected after the accomplishment of cost reduction or after the development of its attractive applications which meet user's needs. Also, PEFC (Polymer Electrolyte Fuel Cell) has been on development aggressively, of its attractive features for use of automobile and stationary power source. This report focused on these two types of fuel cells, PAFC and PEFC, and describes their characteristics, system, typical introduction examples of new application or development status. It is expected that these newly developed environment friendly fuel cell systems would be accepted and penetrated in the market, and contribute to the preservation of global environment.
