  1. Developments of a Fuel Cell Micro-Grid Technology 9th International Symposium on Advances in Electrochemical Science and Technology (Chennai, India) December 3, 2010. Dr. Shin’ya Obara Department of Electrical and Electronic Engineering Power Engineering Laboratory Kitami Institute of Technology, Japan

  2. Capacity and Efficiencyof the Power System MCFC： Molten carbonate fuel cell PEFC： Proton-exchange membrane fuel cell SOFC： Solid-oxide fuel cell MGT : Micro gas turbine • The evidence examination of SOFC for stationing is started from 2007. • Microgrid is expected as a next-generation distributed power source.

  3. Outline of Home Cogeneration Using a Small-Scale PEFC in Japan Energyfarm=ENE･FARM Produce: Japanese gas companies and oil company (from 2009) System: PEFC,Two-line use with commercial electric power Electric power: 300~1000W Fuel:NaturalgasorLPG(liquefied petroleum gas) Price: 3.5 million JPY (42 thousand USD, 2 million INR) 1.4 million (40%) is supported by Japanese government. Average total efficiency: 70 ~ 80 % (cogeneration) Cost efficiency: Energy cost reduction per year 40 ~ 50 thousand JPY Drastic reduction of prices, or reduction of the recovery year of facility cost is required for the spread of home fuel cell.
