固体電解質型燃料電池の開発－１１０平方ｃｍ級単セルの試作および発電試験結果－

タイトル（英文）

SOLID-OXIDE FUEL CELLS -TRIAL PRODUCT AND SINGLE-CELL PERFORMANCE OF LARGE SOFC

概要 （図表や脚注は「報告書全文」に掲載しております）

発電面積１１０平方ｃｍの固体電解質型燃料電池を発電試験した結果，高出力密度発電で４１Ｗ（Ｈ２／Ｏ２），３４Ｗ（Ｈ２／Ａｉｒ）を得た。均等なガス流配と適切な集電方法を用いれば，小型単セルと同等の性能が得られることを実証した。

概要 （英文）

THERE IS GROWING INTEREST IN DEVELOPMENT OF PLANAR SOLID-OXIDE FUEL CELLS BECAUSE THEY ARE EXPECTED TO HAVE HIGH EFFICIENCY AND HIGH POWER DENSITY FOR ELECTRIC POWER GENERATION SYSTEMS. IN 1990,CRIEPI SUCCEEDED IN GENERATING ELECTRICITY USING SMALL SINGLE CELLS WITH A 3-SQUARE CM ELECTRODE AREA. AS THE NEXT STEP,CRIEPI MADE LARGE SINGLE CELLS WITH A GENERATION AREA EXCEEDING 100 SQUARE CM AND EXAMINED THE PERFORMANCE. THE SINGLE CELL USED IN THE TEST WAS 13CM PHI AND 300- M THICK. THE EFFECTIVE ELECTRODE AREA WAS ABOUT 110 SQUARE CM. THE MAXIMUM CELL POWER AT 1000 DEGREE UNDER O2 AND H2 WAS ABOUT 41 W AT 60 A AND 0.68 V.
