“…While water molecules in a matrix are used for proton transport, water uptake is required to not be too great because excess water uptake may lead to low mechanical stability and other undesirable mechanical properties [39]. Xu and coworkers reported the water uptake of PEM to be in the range of 2.51 -67.23 % at 25 °C.…”

Highlight Mordenite and analcime were used as fillers in Nafion composite membranes for DMFC. The composite membranes were fabricated by spray method. Methanol permeability was reduced up to 2-3 times using the composite membranes. Mordenite/Naifon membrane showed 2 times higher DMFC performance than Nafion117. AbstractThe aim of this work was to improve proton exchange membranes (PEMs) used in direct methanol fuel cells (DMFCs). A membrane with a high proton conductivity and low methanol permeability was required. Zeolite filler in Nafion (NF matrix) composite membranes were prepared using two types of zeolite, mordenite (MOR) and analcime (ANA). Spray method was used to prepare the composite membranes, and properties of the membranes were investigated: mechanical properties, solubility, water and methanol uptake, ion-exchange capacity (IEC), proton conductivity, methanol permeability, and DMFC performance. It was found that MOR filler showed higher performance than ANA. The MOR/Nafion composite membrane gave better properties than ANA/Nafion composite membrane, including a higher proton conductivity and a methanol permeability that was 2 -3 times lower. The highest DMFC performance (10.75 mW·cm -2 ) was obtained at 70 °C and with 2 M methanol, with a value 1.5 times higher than that of ANA/Nafion composite membrane and two times higher than that of commercial Nafion 117 (NF 117).

To date high ionic conducting polymer electrolytes are of great interest because of their potential applications in various electrochemical devices such as batteries, fuel cells, solar cells and super capacitors etc., as electrolytes. Ion conduction through polymer electrolytes can occur mostly in amorphous environment exists above their glass transition temperature (Tg). In order to improve ionic conductivity, many approaches such as addition of plasticizer, blending of polymers, nano composite have been employed. This paper reviews the influence of different plasticizers/additives on the ion transport mechanism of Poly(vinyl alcohol) (PVA)-LiClO4 polymer electrolytes since poly vinyl alcohol is a semi crystalline, synthetic biodegradable polymer and lithium perchlorate is one of the most moisture resistant lithium salts. This review also reveals the relation between dynamical disorder in polymer electrolyte with ionic conductivity.

“…Alternatives or modifications and inorganic-organic composite membranes have been prepared to replace Nafion for exploring new types of PEMs. With this development trend, large quantities of sulfonated aromatic polymers have been explored as alternative PEMs to Nafion, such as sulfonated poly(arylene ether nitrile)s (Zheng et al, 2017a(Zheng et al, ,b, 2018Feng et al, 2018), sulfonated polyimides (Perrot et al, 2011;Yin et al, 2011;Yao et al, 2015;Zhang et al, 2017), sulfonated poly(benzimidazole)s (Li et al, 2009;Yue et al, 2015Yue et al, , 2016Singha et al, 2016), sulfonated poly(arylene ether ketone)s (Pang et al, 2015;Xu et al, 2015;Nguyen et al, 2016;Oh et al, 2016), and sulfonated poly(arylene ether sulfone)s (Ko et al, 2015;Kim et al, 2017a,b;Ahn et al, 2018).…”

Metal-organic frameworks (MOFs), as newly emerging filler materials for polyelectrolytes, show many compelling intrinsic features, such as variable structural designability and modifiability of proton conductivity. In this manuscript, UiO-66-NH 2 , a stable MOF with -NH 2 functional groups in its ligands, was selected to achieve a high-performance sulfonated poly(arylene ether nitrile)s (SPENs)/UiO-66-NH 2 -x covalent-ionically cross-linked composite membrane. Simultaneously, the obtained composite membranes displayed excellent thermal stability and dimensional stability. The as-prepared SPEN/UiO-66-NH 2 -x cross-linked membranes exhibited higher proton conductivity than recast SPENs, which can be attributed to the construction of ionic clusters and well-connected ionic nanochannels along the interface between UiO-66-NH 2 -x and SPEN matrix via molecular interactions. Meanwhile, the methanol permeability of the SPEN/UiO-66-NH 2 -x composite membrane had been effectively reduced due to the barrier effect of cross-linking and the addition of UiO-66-NH 2 -x. The SPEN/UiO-66-NH 2 -5 composite membrane had the highest selectivity of 6.42 × 10 5 S·s·cm −3 : 14.3-times higher than that of Nafion 117. The preparation of cross-linked UiO-66-NH 2 /SPEN composite was facile, which provides a new strategy for preparing high performance proton exchange membrane.
