Mordenite-incorporated PVA–PSSA membranes as electrolytes for DMFCs

Direct methanol fuel cell based on poly(vinyl alcohol)/titanium oxide nanotubes/poly(styrene sulfonic acid) (PVA/nt-TiO2/PSSA) composite polymer membrane

“…It was found that the peak power densities of the DMFCs with these Furthermore, Qiao et al [34] prepared the proton-conducting composite membranes based on high molecular weight PVA and poly(2-acrylamido-2-methyl-1-propanesulfonic acid) (PAMPS) for DMFC applications. The peak power density of the DMFC fabricated with the acidic PVA/PAMPS membrane was 15.8 mW cm −2 at 30 • C, which reached 42.9 mW cm −2 at 80 • C. Recently, Bhat et al [35] studied the poly(vinyl alcohol)/polystyrene sulfonic acid/mordenite (PVA/PSSA/MOR) composite blend membrane for DMFCs. The peak power density of 74 mW cm −2 was achieved for the DMFC using PVA/PSSA electrolyte with 50% degree of sulfonation and 10 wt.% mordenite (MOR) at 70 • C. These comparisons indicate that the DMFC comprised of the PVA/nt-TiO 2 /PSSA composite membrane showed excellent electrochemical performance under ambient conditions.…”

Natural and synthetic solid polymer hybrid dual network membranes as electrolytes for direct methanol fuel cells

“…Thermal properties of the membranes Three main degradation stages occur due to the processes of thermal dehydration, thermal degradation, and thermal decomposition of the polymeric membranes as shown in Fig. 6 [40,46,67,68]. The first weight loss between 0 and 200°C is due to the loss of absorbed water molecules from the CS-PVA-GA and CS-PVA-SSA matrix.…”

“…Our recent findings suggest that PVA-PSSA, modernite (MOR)-incorporated PVA-PSSA with varying degrees of sulfonation, and PVA-SSA-HPA composite membranes exhibit attractive mechanical stability and provide promising DMFC performance [45][46][47]. It was also found that CS-hydroxyethyl cellulose (HEC), CSgelatin (GL), and sodium alginate (NaAlg)-PVA blends on modification by incorporating HPAs can be successfully employed as solid polymer electrolyte membranes for DMFCs owing to their low cost and excellent methanol barrier properties in relation to commercially available membranes [40,48,49].…”
