The microstructure and the properties of nickel diffusion layer were also investigated 同時,對擴散層的組織和性能進行了研究。
In addition , treating the cathode diffusion layer with ptfe can further enhance the cell performance 另外,通過對陰極擴散層的疏水處理,有效地改善了陰極水的排出,進一步提高了電池性能。
The studied domain consists of fluid channels , diffusion layers and catalyst layers of anode and cathode , and membrane 研究的區域包括陽極和陰極的流道、擴散層和催化層,以及中間的質子交換膜在內的整個電池。
For pc , the pulse diffusion layer only depends on the diffusion coefficient of cations and the pulse length , is not related to the concentration of the mass 單脈沖擴散層的厚度僅取決于陽離子擴散系數和脈沖導通時間,與溶液本體濃度無關。
The function of diffusion layer and hydrophobic layer is affected by channel and depends on the pore diameter , the porosity and the thickness of diffusion layer and catalyst layer 擴散層和疏水層對氣體作用的結果受流道影響,取決于孔徑、空隙率和厚度的變化。
When the width of the channel is unchangeable , the more are the numbers of the channels , the narrower the channel becomes , the evener the oxygen on the surface of diffusion layer becomes 當流道寬度不變時,流道數目越多,流道間隔越窄,越有利于氧氣在擴散層表面上的均勻化分布。
The decrease of active surface area in the anode caused by co2 accumulation is reduced through treating the diffusion layer and catalyst layer with ptfe , resulting in increased dmfc performance 通過對陽極擴散層和催化劑層的疏水處理,降低了陽極產生的co2導致的催化活性比表面積損失,有效地提高了電池性能。
The research results show that the radius of the gas channels and the electronic conductivity in carbon phase of the reaction layer , and the porosity of the gas diffusion layer are relatively less important 研究結果表明氣體擴散層孔隙率,反應層氣體通道的半徑以及碳相中電子傳導率等參數的變化對電極性能影響不大。
The thin - film and flooded - agglomerate ( tffa ) model assumes that the oxygen diffusion electrode made of a gas - diffusion layer and a reaction layer possesses a double - scales of porous structure in the reaction layer 薄膜浸漬聚集體( tffa )模型假定由氣體擴散層和反應層構成的氧氣擴散電極在反應層中是一種二次構造形式的多孔結構。
The calculation results show that the radius of the gas channels in the reaction layer and the porosity and average pore radius of the gas - diffusion layer seem to be less important for the performance of the electrode 模型結果表明對于電極性能而言,氣體擴散層的孔隙率與平均孔徑以及反應層氣體通道的半徑,相對其他參數來說顯得不太重要。
In the electrochemistry, the diffusion layer contains the material that is analyzed. According to IUPAC, the diffusion layer is defined as the "region in the vicinity of an electrode where the concentrations are different from their value in the bulk solution.
