Capacity and Efficiency of 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.

(from 2009) System PEFC, Two-line use with
commercial electric power Electric power 300
1000 W Fuel Natural gas or LPG (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.
