本文將tffa模型應用於堿性燃料電池（ afc ）和質子交換膜燃料電池（ pemfc ）陰極，推導出陰極各種傳遞和反應過程的描述方程，包括氧氣在氣體擴散層和反應層氣體通道中的擴散，氧氣在反應層薄膜中的溶解和擴散，氧在反應層浸漬聚集體中的反應和擴散以及電子和離子的傳導，並給出方程的數值解法。Ir - ta - ti metal oxide coated titanium anodes of variable composition were prepared by thermal decomposition. their micro morphorogies and electrochemical properties were characterized by scanning electron microscope, open circuit potential, cyclic voltammetry, consumption rate measurements and accelerated life test. the sem results indicated that all coatings were of a porous and cracked - mud microstructure influenced greatly by the composition of coatings. the electrochemical measurements showed that the ir - ta - ti ternary oxide - coated anodes exhibited excellent electrochemical activity and electrochemical stability in both acidic media and seawater which were affected by the composition and microstructure of the coatings. owing to good corrosion resistance and low consumption rate in seawater, metal oxde coated anodes belong to insoluble material, and can be potentially applid in impressed current cathodic protection systems as an anode
採用熱分解方法在鈦基體上制備銥鉭鈦金屬氧化物陽極，用掃描電鏡對陽極塗層顯微形貌進行分析，通過強化電解壽命試驗、開路電位測試、消耗率試驗及循環伏安曲線研究了金屬氧化物陽極的電化學性能. sem分析結果表明銥鉭鈦金屬氧化物陽極塗層呈現多孔多裂紋形貌結構.隨陽極塗層組成不同，塗層顯微形貌表現出很大差異，這種差異直接影響陽極電化學性能.電化學性能試驗結果表明銥鉭鈦金屬氧化物陽極在酸性介質和海水中具有良好的電化學穩定性和電化學活性.此外，銥鉭鈦金屬氧化物陽極在海水中的消耗率很低，屬于不溶性的陽極材料，作為外加電流陰極保護用輔助陽極具有廣泛的應用前景Determination of trace selenium in selenium - riched yeast by cathodic stripping voltammetry
陰極溶出伏安法測定硒酵母中微量硒As a new method of polymerization, electroless polymerization was introduced to form polyaniline film on substrate of any shape. in electroless polymerization, aniline molecules were oxidized to form pn film by soluble oxygen on the catalytic surface of pt or pd substrate without the supply of electric current. similar to the mechanism of electroless plating, electroless polymerization of aniline involves local and spontaneous electrochemical reactions on only substrate
提出了一種新的聚合方法無電聚合。在沒有外電流的情況下，溶液中的苯胺分子在具有催化活性的鉑或鈀基底表面上被溶解氧氧化為聚苯胺膜。與化學鍍的原理類似，苯胺的無電聚合反應過程包含陰極半反應和陽極半反應兩個電化學反應。The analytic results of the effects on the micromorphological structure of the film by the electrochemical condition ' s showed that the carbon is apt to improve the boundary combination between the scfs and the surface of the cathode and the seperation of the films, and that the micromorphological structure of the mpgcfs is greatly affected by the dring and the power voltage, which remarkably affluence ion move in swelling cathode film, and that higher temperature and concentration of cu2 + in the medium solution are also advanagable to the deposition of cu in scfs. the plot of deformation behavior of mpgcfs showed that the maximum strench ratio decreases and the brittleness increases due to the existence of the metal phase, and that the strengh trend of the composite films is fistly up and down followed with the content of metal phase because of the change of the role of the metal phase from acting as the physical cross - linking to weakening the films due to destroying the whole structure of the polymer
另外它作為基體的另一個突出的優點是制備的溶脹復合膜（ scf ）中的溶劑與電解液中的溶劑相同都是水，克服了以前膜內外不同溶劑之間擴散的問題，結果使得電流最終趨於一種穩態，因此可以更好實現用電化學條件來控制mpgcf的形態結構；硬質石墨材料的多孔的結構和石墨本身的結構性能特點使得碳作為陰極材料時有利於溶漲復合膜（ scf ）與電極表面的結合以及膜的剝離，因此是作為陰極的理想材料；電化學條件中的乾燥程度和電壓能夠明顯的影響離子在膜內的遷移，從而對mpgcf的形態結構造成較大的影響；而提高反應溫度和增大電解液中銅離子的濃度也有利於銅在膜中的沉積生長。分享友人
