PTFE-nafion membrane reactor for hydrogen production

The impact of using a proton exchange membrane on alkaline fuel cell performance

“…Following the parameters set by the electrochemistry, high current densities do not favour energy efficiency, so in this experiment the potentials at 1, 1.23 and 5.0 V, allow us to obtain higher energy efficiency [9,10]. Figure 4 shows the current density when the coupled hydrogen fuel cell with the Nafion 117 membrane is used.…”

“…The studies were performed at constant temperature (300 K), applying Henry's law [9,13], as shown in Eq. (5):…”

Fabrication and characterization of a novel Nafion‐PTFE composite hollow fiber membrane

“…Therefore, the preparation of a composite membrane should be an effective method to reduce Nafion consumption. Many studies have been done to perform a composite membrane with a porous polytetrafluoroethylene (PTFE) membrane as the substrate for its outstanding solvent resistance and good chemical and thermal stability 24–31 . In these studies; however, the Nafion resin was required to impregnate into porous PTFE membrane as thorough as possible to ensure the ion conductivity and operation stability.…”

“…Many studies have been done to perform a composite membrane with a porous polytetrafluoroethylene (PTFE) membrane as the substrate for its outstanding solvent resistance and good chemical and thermal stability. [24][25][26][27][28][29][30][31] In these studies; however, the Nafion resin was required to impregnate into porous PTFE membrane as thorough as possible to ensure the ion conductivity and operation stability. However, as for other usages, like gas separation or pervaporation, the filling of Nafion in the PTFE pores can result in an extra mass transfer resistance and increase the consumption of Nafion.…”
