熱可塑性樹脂、導電性フィラー、及び親水性無機集合体を、表1及び表2に記載された含有量で使用して、下記実施例1乃至6及び比較例1乃至7の燃料電池用バイポーラプレートをそれぞれ製造した。
燃料電池用バイポーラプレートの樹脂基材を形成するために、熱可塑性樹脂としてポリフェニレンサルファイド(polyphenylene sulfide:PPS)樹脂を使用した。このようなポリフェニレンサルファイドとして、315.5℃の温度及び窒素雰囲気において測定した零粘度(Zero viscosity)が、300[P]である、Chevron Phillips Chemical(CPC)社のRyton PR−11(登録商標)を使用した。
バイポーラプレートの炭素系導電性フィラーとして、平均直径が100μmである人工のグラファイトを使用した。
マイクロスケールの二酸化チタン粒子の表面に、ナノスケールのカーボンブラック粒子が埋込まれたハイブリッド粒子を含む親水性無機集合体を使用した。ナノスケールのカーボンブラック粒子は、ASTM D3037−89測定法による表面積が70m2/gであり、超音波放射器で超音波を10分加えた後の平均直径が35nmであった。マイクロスケールの二酸化チタン粒子は、J.Phys.Chem.98(1994)1366に記載された方法に応じて、チタニウムテトライソプロポキシドの調節された加水分解から得られ、平均直径5.3μmであった。
