PEFC utilizes polymer membrane, and has a feature of relatively low working temperature. It is also characterized by easiness of start-up and shut-down and high power density compared with other types of fuelcells. Development of PEFC for stationery uses is actively performed in Japan. Development of lkW class PEFC fueled by natural gas and LPG for residential use has been advanced, and more than 3,300 units of PEFC were installed in actual houses for four years from 2005 to 2008 in the demonstration project implemented by the government. From 2009, lkW residential PEFC has been released on the market with the government support for the installation of JPY 1.4 million per one unit. The reason the government has provided much support for the commercialization of PEFC is its excellent performance. The power generation efficiency of the most advanced model reached 37 %, and total efficiency reached nearly 90% with heat recovery efficiency which excelled 50%. According to the results of a number of the demonstration units, CO_2 reduction per one site reached 1.2 ton per year on average.
