Abstract
Description
103:燃料極用の触媒層
104:電解質膜
105:酸化剤極用の触媒層
106:酸化剤極用のガス拡散層
触媒粒子の下地層となるアルミニウム(純アルミニウム)をスパッタリング処理より基板(基体)の表面に成膜させた。アルミニウムの膜の厚みは4~6ナノメートル(5ナノメートル)とした。その後、基板の表面をアセトンで洗浄した。基板は4インチ四方のシリコン基板(厚み:0.5ミリメートル)とした。全部の試験例について共通条件とした。
所定濃度となるように、アルコールであるエタノールに、硝酸鉄(III)・9水和物を常温にて投入した。その後、常温にてスターラ(攪拌機)により攪拌し、触媒液を形成した。触媒液には、テルピネオールは配合されていない。従って触媒液はテルピネオールを含まない。更に、触媒液には、増粘作用をもつポリアクリル酸ナトリウム、ポリビニルアルコール、ポリエチレンオキシド、ポリビニルピロリドン、精油も配合されていない。このため触媒液には、テルピネオール、ポリアクリル酸ナトリウム、ポリビニルアルコール、ポリエチレンオキシド、ポリビニルピロリドン、精油は含まれていない。この場合、試験例1では触媒液の濃度は0.05Mとした。試験例2では触媒液の濃度は0.1Mとした。試験例3では触媒液の濃度は0.2Mとした。試験例4では触媒液の濃度は0.3Mとした。試験例5では触媒液の濃度は0.4Mとした。試験例6では触媒液の濃度は0.5Mとした。試験例7では触媒液の濃度は0.6Mとした。試験例8では触媒液の濃度は0.7Mとした。試験例9では触媒液の濃度は0.8Mとした。試験例10では触媒液の濃度は0.9Mとした。試験例11では触媒液の濃度は1Mとした。試験例12では触媒液の濃度は1.1Mとした。
常温にて基板をディップコータにより上記触媒液に10秒間浸漬させた。その後、60ミリメートル/minの速度で基板を触媒液から引き上げた。その後、100℃×5分間で大気中において基板を乾燥させた。これにより触媒粒子を有する触媒層を基板の表面に形成した。これにより複数の島状をなす複数個の触媒粒子が分散した群を基板の表面に形成した。
熱CVD装置を用い、予め10Paに真空引きされた反応容器中にキャリヤガスとして窒素ガスを導入し、反応容器内の圧力を0.1MPaに調整した。その後、反応容器内の基板の温度を750℃に昇温させた状態で、流量10sccmのアセチレンガスと45sccmの窒素とが混合した原料ガスを反応容器内に供給した。sccmは、standard cc/minの略であり、1atm、0℃で規格化されたccmを示す。そして原料ガスの雰囲気下で、基板温度750℃
、266Paの雰囲気において10分間反応させることにより、カーボンナノチューブを基板の表面に生成させた。この結果、基板の表面においてカーボンナノチューブからなる群が得られた。なお基板温度は750℃であり、金属塩触媒上における反応ガスの分解の促進を考慮したものである。
上記した試験例1~12は、テルピネオール等の増粘剤を配合していない触媒液を用いて実施されている。この場合、触媒液の溶媒はエタノール100%とされている。試験例1~12によって製造されたカーボンナノチューブのSEM写真を、触媒液の濃度毎に図1に示す。図1から理解できるように、テルピネオールを配合していない触媒液が用いられている場合には、試験例1(触媒液の濃度:0.05M)ではカーボンナノチューブは良好に成長せず、カーボンナノチューブの垂直配向性は良好ではなかった。更に、試験例2(触媒液の濃度:0.1M)ではカーボンナノチューブの垂直配向性は良好ではなかった。
試験例1(触媒液の濃度:0.05M)… 3マイクロメートル程度
試験例2(触媒液の濃度:0.1M)… 7~30マイクロメートル程度
試験例3(触媒液の濃度:0.2M)… 50マイクロメートル程度
試験例4(触媒液の濃度:0.3M)… 35マイクロメートル程度
試験例5(触媒液の濃度:0.4M)… 60マイクロメートル程度
試験例6(触媒液の濃度:0.5M)… 60マイクロメートル程度
試験例7(触媒液の濃度:0.6M)… 40マイクロメートル程度
試験例8(触媒液の濃度:0.7M)… 25マイクロメートル程度
試験例9(触媒液の濃度:0.8M)… 45マイクロメートル程度
試験例10(触媒液の濃度:0.9M)… 2マイクロメートル程度
試験例11(触媒液の濃度:1M)… 2マイクロメートル程度
試験例12(触媒液の濃度:1.1M)… 17マイクロメートル程度
図3はシート型の高分子形の燃料電池の要部の断面を模式的に示す。燃料電池は、燃料極用の配流板101と、燃料極用のガス拡散層102と、燃料極用の触媒を有する触媒層103と、炭化フッ素系または炭化水素系の高分子材料で形成されたイオン伝導性(プロトン伝導性)を有する電解質膜104と、酸化剤極用の触媒を有する触媒層105と、酸化剤極用のガス拡散層106と、酸化剤極用の配流板107とを厚み方向に順に積層して形成されている。ガス拡散層102,106は、反応ガスを透過できるようにガス透過性を有する。電解質膜104はイオン伝導性(プロトン伝導性)を有するガラス系で形成しても良い。
図4は集電用のキャパシタを模式的に示す。キャパシタは、炭素系材料で形成された多孔質の正極201と、炭素系材料で形成された多孔質の負極202と、正極201および負極202を仕切るセパレータ203とを有する。正極201の表面に対して垂直方向に沿った垂直配向性をもつカーボンナノチューブが正極201の表面に設けられている。負極202の表面に対して垂直方向に沿った垂直配向性をもつカーボンナノチューブが負極202の表面に設けられている。本発明に係るカーボンナノチューブは、大きな比表面積をもち、多孔質であるため、正極201および/または負極202に使用されるとき、集電容量の増加を期待でき、キャパシタの能力を向上できる。基板に形成されたカーボンナノチューブを負極202、正極201の表面に転写させることができる。
