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).

“…They are hydrophilic substances with molecular sieve properties [5,12], preferring to adsorb water to alcohol and providing a good proton pathway through the membrane while blocking the diffusion path of alcohol inside a Nafion composite membrane. In addition, mordenite and analcime are stable in acid and have high temperature tolerance.…”

“…Several works have been reported on Nafion-zeolite composite membranes, including reports on the incorporation of acid functionalized zeolites to improve the proton conductivity of the composite membrane [25,[30][31][32] or to improve the dispersion of the zeolite particles, and studies on the effect of the zeolite particle size, the Si/Al ratio [33], or the solvent used in membrane fabrication. Some of these studies confirmed that zeolites can improve the performance of Nafion based DMFCs operating at temperature higher than 70 • C and with O 2 fed at the cathode, although the impact of the zeolite incorporation on the proton conductivity and methanol permeability of membranes varies between the reported works.…”

a b s t r a c tAlthough zeolites are introduced to decrease methanol crossover of Nafion membranes for direct methanol fuel cells (DMFCs), little is known about the effect of their intrinsic properties and the interaction with the ionomer. In this work, Nafion-Faujasite composite membranes prepared by solution casting were characterized by extensive physicochemical and electrochemical techniques. Faujasite was found to undergo severe dealumination during the membrane activation, but its structure remained intact. The zeolite interacts with Nafion probably through hydrogen bonding between Si-OH and SO 3 H groups, which combined with the increase of the water uptake and the water mobility, and the addition of a less conductive phase (the zeolite) leads to an optimum proton conductivity between 0.98 and 2 wt% of zeolite. Hot pressing the membranes before their assembling with the electrodes enhanced the DMFC performance by reducing the methanol crossover and the serial resistance.

“…The zeolite itself has a similarity to other PEM materials which makes it suitable for a DAFC. The zeolite membrane may appear in the form of pure zeolite itself, 68 as a composite with mentioned materials 73,75,76,[81][82][83] or as a composite form with other new materials. 84 Compared to the existing membrane materials, the zeolite composite membranes give improved performance in term of proton conductivity and alcohol crossover.…”

Abstract. The increase of energy demand and global warming issues has driven studies of alternative energy sources. The polymer electrolyte membrane fuel cell (PEMFC) can be an alternative energy source by (partially) replacing the use of fossil fuel which is in line with the green technology concept. However, the usage of hydrogen as a fuel has several disadvantages mainly transportation and storage related to its safety aspects. Recently, alcohol has gained attention as an energy source for fuel cell application, namely direct alcohol fuel cell (DAFC). Among alcohols, high-mass energy density methanol and ethanol are widely used as direct methanol fuel cell (DMFC) and direct ethanol fuel cell (DEFC), respectively. Currently, the performance of DMFC is still rudimentary. Furthermore, the use of ethanol gives some additional privileges such as non-toxic property, renewable, ease of production in great quantity by the fermentation of sugar-containing raw materials. Direct alcohol fuel cell (DAFC) still has weakness in the low proton conductivity and high alcohol crossover. Therefore, to increase the performance of DAFC, modification using zeolite has been performed to improve proton conductivity and decrease alcohol crossover. Zeolite also has high thermal resistance properties, thereby increasing DAFC performance. This paper will discuss briefly about modification of catalyst and membrane for DAFC using zeolite. Zeolite modification effect on fuel cell performance especially proton conductivity and alcohol crossover will be presented in detail.
