Witryna15 sie 2024 · A nitrogen-stabilized single-atom catalyst containing low-valence zinc atoms (Zn δ+-NC) is reported.It contains saturated four-coordinate (Zn-N 4) and … WitrynaNafion™ polymer functions as an acid catalyst due to the strongly acid properties of the sulfonic acid group. Nafion™ polymer functions as an ion exchange resin when exposed to solutions. Nafion™ polymer very readily absorbs water, from the vapor phase or from the liquid phase. Each sulfonic acid group will absorb up to 13 molecules of water.

As shown in Fig. 3b, the high frequency resistance and the charge transfer resistance of the directly deposited membrane are significantly lower than the reference MEA with Nafion® HP membrane. We find an R ct 2 for the directly deposited membrane whereas the Nafion HP fuel cell reveals an R … WitrynaThe free volume size V f for Nafion® HP JP reflect the α-transition temperature at about 98°C. In addition the free volume size V f for Nafion® HP JP is smaller than that for Nafion® NRE212 membrane which leads to lower methanol permeability of the former membrane. The proton conductivity σ for Nafion® HP JP decreases with increase of ... columbus oh city tax
