Based on previous research and development, Nippon Oil Corporation (NOC) has been developing stationary Polymer Electrolyte Fuel Cell (PEFC) systems that use petroleum fuels since 1999.
NOC have developed a 1-kW class powered petroleum gas (LPG) powered stationary PEFC system was co-developed with SANYO Electric Co., Ltd. Under a joint development and started commercial sales in March, 2005. The power generation efficiency of the unit is 34%. The total energy efficiency is achieved to 76% in this unit by the heat recovery system. NOC will install 150 fuel cell systems within 2005 fiscal year.
In April 2004, kerosene powered 1kW PEFC stationary demonstration system was co-developed with EBARA Ballard CORPORATION under a joint development. The power generation efficiency of the unit is 33%. The total energy efficiency is achieved to 76% in this unit by the heat recovery system. The system was also tested below freezing point and was confirmed operability without any problem. A power generation efficiency of 36% will be achieved as a target in the next generation. After realizing an improvement of electrical efficiency and overall efficiency and downsizing, and passing through a field examination from now on, the early market injection is aimed at.
