Fuel cell is considered as the fourth generation power system after thermal power,hydropower,nuclear power generation,it has been known as the most century clean,efficient power source in 21st century,received widespread attention at home and abroad. In this paper,based on the fundamental principle of fuel cell,several main kinds of fuel cells are introduced. The practical experience in markets for fuel cell is summed up. The proton exchange membrane fuel cell (PEMFC) and solid oxide fuel cell (SOFC),methanol fuel cell (DMFC) are reviewed on the basic principle,development status of fuel cell,the latest market applications and future development directions as they have been received much rapid development in recent years. Combining with the great pressure of energy shortage and environment pollution,we proposed a suitable fuel cell technology development scheme for Macao and other densely populated areas. <<
