平成27 年頃以降の普及期に対応すべく最優先しなければならないシステムのコスト低減と性能、耐久性を主とする商品性を両立する革新的技術開発を目的とし、以下に示す4 つのサブテーマに取り組む。各サブテーマを推進するに当たっては、サブテーマ毎にワーキンググループ(以下、WG と記載)を設定した。
英文要約Title: Strategic Development of PEFC Technologies for Practical Application/ Development of Fundamental Technology/ Performance Improvement of Membrane Electrode Assembly (MEA) of PEFC for Cost Reduction of Stationary Co-generation Systems (FY2010-FY2011)/ FY2010 Annual Report Significant cost reduction is required for the full-fledged commercialization of residential PEFC co-generation systems. The objectives of this project are to develop the reliable and robust MEA components and associated sub-systems, which contribute to simplify the whole system with reduced cost.

The final targets are:
1) To develop the polymer electrolytes which can keep the same cell voltage under the conditions of high temperature (Tcell = 80-90°C) and low relative humidity (anode dew point Tda = 60°C with supplying dry air to the cathode) as that under the previous conditions (Tcell = 80°C, Tda = Tdc = 65°C).
2) To develop highly CO-tolerant anode catalysts and the optimized operation conditions, resulting in the voltage loss < 20 mV operated with reformate containing 500 ppm CO.
3) To develop durable CO shift catalysts and CO selective methanation catalysts which can keep the CO concentration below 500 ppm at the exit of the reformer to simplify the CO reduction subsystem for the reformer.
4) To develop the evaluation technology to predict the effects of impurities in the fuel or air on the cell voltages.
We made effort to improve the MEA components, and achieved the following results.

1)Electrolyte material suppliers have improved the conductivity of the electrolyte materials at the high temperature and low humidity conditions. We have also standardized the tests and test conditions for Electrolyte materials.
2) We have succeeded to prepare new anode catalysts (Pt-Ru and Pt-Ru with rhodium porphyrin) having higher CO-tolerance than the commercial one. The CO-tolerant mechanism has been analyzed. These developed catalysts have been examined in MEAs. It was found that new MEAs exhibited lower voltage loss and higher durability.
3) We have succeeded to prepare candidates of the CO-shift catalysts (Cu262,Cu266) which shows the potential of high performance and durability and found the design guide to achieve both high performance for CO selective methanation reaction and low CO2 methanation reaction. We also found the operating condition as the basic data to design the subsystem.
4) We have accumulated and classified the basic data. We also made effort to find out the governing parameters to predict the effects of impurities, and showed some candidates.
