Description
− 金属塩の電気めっきの工程が、前記金属粒子の表面上への高い吸収力を有し且つ前記金属塩の還元電位よりも高い酸化電位を有するブロッキング化学種の存在下で行なわれ、
・ その結果、ブロッキング化学種が、前記金属塩の還元反応の間そのブロッキング力を保存し、
・ 前記電気導電性触媒電極を構成する形成された金属粒子の大きさを低減する工程と、
− ブロッキング化学種の脱着の工程と
を含むことを特徴とする方法である。
− H2PtCl6酸性溶液、
− 硫酸、
− Na2SO3の存在下で行なわれる。
− 粒子の大きさ。基本的には成長抑制種の量および吸着力だけが粒子の大きさに影響を与えるはずであるので、これは理論においては金属の充填とは関わりがないため。
−特に簡単な酸化によってブロッキング種を容易に除去できること。これは、Pt上への水素の吸着および脱着を示すPt電極の電気化学的特徴に関して固有領域に相当する表面の0.05V〜0.3VERHの間の増加をモニタすることにより電極の表面がブロッキングガスを全く含有しないかどうかin situ観察することによって行なわれる。Eに対してボルタモグラムiにこれらのピークが存在しないことは、サイクルを繰り返した後で別の種による白金の吸着部位のブロッキングを示す。
− 燃料電池の文脈において、そして粘性液体の使用が触媒効果に強く影響を与える場合がある先行技術において行なわれているものとは逆に、ガス種を使用することによって酸素の還元のために同様に関与させられる部位に達することができること。
− COは、空気中で20ppmで白金吸着部位のほとんど完全なブロッキング(96%)を可能にする。
− 酸化窒素については、たった400ppbで全ての吸着部位の固定化が得られる。
− 二酸化硫黄については、同じ結果を得るために500ppbが必要である。
− プロパンもまた重要であり得、90ppmで当該部位を全てブロッキングする。
電気化学的堆積が商用拡散層(Sigracet(商標)製のSGL“Gas Diffusion Layer”GDL)などの多孔性炭素支持体上の電気めっきセル内で行われる。電気めっきセルは、その上に堆積が行われる作用電極から1cm離れたタンタルフォーム対向電極を含む。
jpcは、パルスの間に印加された電流:100mA/cm2である。
θonはパルス時間であり、10msに等しい。
θoffは2つのパルスの間の時間:180msである。
npeaksはパルス数であり、この実施例においてそれは24である。
