oxidation reduction catalyst 解釋
氧化還原催化劑
  • oxidation : n. 【化學】氧化(作用),正化。
  • reduction : n 1 縮小,減少;降級,降位;(刑罰等的)輕減;減速;減價,折扣。2 (城市、國家等的)陷落,投降,...
  • catalyst : n. 【化學】觸媒,催化劑,接觸劑〈又作 catalytic agent〉;〈比喻〉觸發因素,〈口語〉(善用熱情、言語等打動他人的)有感染力的人。
  1. Each electrode is impregnated with a catalyst to speed the oxidation reduction or half reaction.

    每個電極摻入催化劑,以加重電池半氧化或還原反應。
  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. Carbon nanotubes ( cnt ) are new promising materials of catalyst supports for pemfcs. previous studies reveal that cnts supported catalysts show enhanced catalytic activity towards oxygen reduction reaction ( orr ) and methanol oxidation
