“…19 Based on the alcohol used, DAFCs can be categorized into two types namely DMFC (direct methanol fuel cell) and DEFC (direct ethanol fuel cell).Both types have been used in laboratory and industrial scale. However, they still have some weakness in their performance because catalyst oxidation is used based pure noble metals (Pt, Au, Pd) 20,21 and high alcohol crossover. To improve the performance of DAFCs, previous studies have modified membrane used, by replacing it to zeolite based membrane.…”

“…Further, graphite based collector is used to collect all electrons obtained in the anode, that it inject electron to the cathode. 20,34,36 The most membrane used in DAFC is Nafion because of its physical properties are suitable to apply in chemical mixture and mild temperature condition up to 80-100°C. 37 However, Nafion has high alcohol crossover, so that permeated methanol or ethanol and its oxidation of the intermediate products could poison the cathode catalyst.…”

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.
