  1. Oxygen diffusion transport and electrochemical reaction in the oxygen cathode of direct methanol fuel cell ( dmfc ) have been expressed with the tffa model. model calculation has been carried out to investigate the effects of structural parameters of the dmfc cathode on the electrode performance, which is respectively represented by the curve of cathode overpotential versus current density. much attention has been paid to parameters including the porosity of the reaction layer, the thickness of the thin - film on the flooded - agglomerate, the radius of the flooded - agglomerate, the volume fraction of the flooded - agglomerates in the reaction layer

    本文首先運用tffa模型描述直接甲醇燃料電池（ dmfc ）陰極氧氣的傳遞和電化學反應過程，研究了過電位-電流密度曲線受陰極結構參數變化的影響程度，其中著重考慮了以下幾個參數：催化層的孔隙率，浸漬聚集體薄膜的厚度，浸漬聚集體的半徑，浸漬聚集體在催化層中的體積分數。
  2. Transport in the diffusion layers and catalyst layers are described by a superposition of knudsen diffusion and stefan - maxwell diffusion, and electrochemical kinetics for anodic methanol oxidation and cathodic oxygen reduction are described by tafel equation

    模型以stefan - maxwell擴散和knudsen擴散的疊加描述了氣體混合物在多孔電極中的擴散過程，以tafel方程描述了甲醇在陽極氧化和氧在陰極還原的電化學動力學。
  3. N sources ( including organic and inorganic n tested ) and c sources tested could restrain methane oxidation. cellulose inhibited methane oxidation most weakly while the high concentration of methanol and glucose did dramatically, but the proper concentration of methanol could stimulate soil methane oxidation sharply. in the middle process of methane oxidation, addition of glucose could restrain methane oxidation shortly but the inhibition could be relieved about 5 days later when supplied again with enough oxygen

    土壤微生物是甲烷氧化的主要生物類群，含水量對土壤甲烷氧化活性有明顯影響，過高或過低對甲烷氧化均具有抑制作用；氮源（包括有機和無機氮源）對甲烷氧化均有抑制作用；不同碳源對甲烷氧化的影響各異，纖維素對甲烷氧化抑制作用最小，而高濃度的甲醇、葡萄糖則對甲烷氧化具有強烈抑制作用；而適當濃度的甲醇可極大促進土壤對甲烷的氧化：在甲烷氧化過程中加入葡萄糖能迅速抑制甲烷氧化；在加入葡萄糖的同時保持瓶中充足的氧氣，則這種抑制作用可以在重新培養一定時間后得到解除。
  4. 6 ), the process that h20 is adsorbed on the electrode surface and the hydroxyl group is formed to oxidize the co may be the rate - determining step ; in the region iil ( logi > l. 6 ), all of the tafel curves show a curvature until the current densities reach the peak value, indicative of a possible limiting current. the effect of rare earth elements on methanol electro - oxidation has not been reported in literatures

    在低極化區（ logi 1 . 3 ） ，甲醇發生脫氫反應並形成反應中間體，其中co成為未被氧化的毒物，此過程成為速率限制步驟；在更高的極化區（ 1 . 3 logi 1 . 6 ） ， h _ 2o吸附在電極表面並解離生成[ oh ] ，促進了co的氧化，此為此階段速率控制步驟：在第3個極化區（ 10gi 1 . 6 ） ， tafel曲線發生彎曲，電流密度也最終達到峰值。
  5.

    文摘:利用苯駢三氮唑、丙醛分別和甲醇、乙醇、丙醇- 1 、丙醇- 2 、丁醇- 1 、丁醇- 2 、 2 -甲基丙醇- 1 、 2 -甲基丁醇- 2反應合成了八種烷氧基烷基苯駢三氮唑，通過元素分析、 ir 、 1hnmr對上述化合物的結構進行了測定，並討論了這類加成反應的歷程。
  6. Special attention is paid to the consequences of methanol crossover in cathode reaction and cathode over - potential. good agreement is found between simulations and experiments in regard to the v - i character of dmfcs. based on the theory of parallel electrode reaction, it becomes possible to obtain quantitatively the value of over - potential caused by methanol crossover, which is either implicit or not included in the overall cathode over - potential in previous models

    該模型涵蓋了dmfc中的主要物理化學過程，包括：甲醇水溶液在膜電極內的擴散、對流和電遷移；質子在陽極催化劑層和陰極催化劑層內的傳遞；氧氣、水蒸汽在陰極的擴散；陽極催化劑層內的甲醇氧化反應動力學；以及陰極催化劑層內的氧還原和甲醇氧化反應動力學。
