新日本石油における家庭用燃料電池システム開発の取り組み

抄録

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.
