The performance of PEMFC with pure oxygen or air as oxidant is experimentally com- pared.
0;相对于阴极通空气的情况,阴极通氧气时电池性能显著提高,故在条件允许的前提下应尽量以纯氧作为氧化气体。

The results showed that NO reduction and NO oxidation.
结果表明:NO还原和氧化在其脱除过程中同时共存,当NO,N2,O2,H2O和CO2的体积浓度分别为200×10-6,80%,5%,6%和9%时,NO氧化所占的比例比NO还原的大很多;脉冲频率增大导致NO还原率和氧化率均增大;H2O浓度增大导致HNO3浓度增大,表明NO氧化所占的比例随H2O浓度增大而增大。
The catalytic activities of four kinds of supports γ Al 2O 3, ZrO 2, TiO 2 and SiO 2 as well as the Pt catalysts supported on them were investigated for the NO oxidation at the reaction temperature 423K.
研究了载体在 SO2 影响 NO催化氧化过程中的作用 ,考察了反应温度为 42 3 K时 ,γ-Al2 O3、Zr O2 、Ti O2 和 Si O2 4种载体及其负载的 Pt催化剂对 NO的氧化性能 ,与 SO2 存在下的 NO反应活性相比 ,只有 γ-Al2 O3及其负载的 Pt催化剂上存在 SO2 促进 NO氧化的现象。
A study is carried out to see the effects of reaction temperatures and / molar ratios on NO oxidation by ozone in a tube reactor.
当[O3]/[NO]=1、反应温度分别为常温和200℃时,NO氧化率都达到100%,而在275℃时,NO氧化率只有72%,表明反应温度影响显著,其原因主要与较高温度下O3分解加快有关。
