“…The decomposition profiles of membranes measured by TGA depend on many factors, including heating rate, gas (nitrogen or oxygen) flow rate, and sample preparation technique (Mishra et al, 2012). There are generally three stages in the decomposition process of membranes: (1) the release of free and bound water molecules; (2) the decomposition of functional groups; and (3) the separation of core series of the membrane (Zakaria et al, 2016). Meanwhile, thermal transition behaviour (glass transition) of PEMs is obtained by differential scanning calorimetry (DSC) study (Tripathi and Shahi, 2011).…”

“…In response to this growing energy demand, several alternative energy technologies have been proposed, among which fuel cell (FC) technology has attracted considerable attention (Ramaswamy et al, 2014 . The utilisation of liquid fuels such as ethanol and methanol in FCs would reduce the requirements of establishing totally new infrastructure as required for hydrogen as a fuel source (Zakaria et al, 2016). Furthermore, both methanol and ethanol are considered renewable fuels (biofuels) when generated from biomass resources.…”

“…Furthermore, both methanol and ethanol are considered renewable fuels (biofuels) when generated from biomass resources. It is worth quoting that currently bioethanol dominates the global biofuel production capacity and can be produced in bulk from biomass feedstocks via a fermentation process (Badwal et al, 2015;Zakaria et al, 2016).…”

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.

Over the past decade or so, alternative energy plays a pivotal role in addressing challenges posed by nature. Polymer electrolyte membrane fuel cell is one of the promising alternative energy and there has been significant research and technological investments done in this field. The key information and future prospective of the field is energy conversion and storage, both of which are essential in order to meet the challenges of global warming and the limited fossil fuel supply. However, polymer membrane in particular plays a crucial role in advancing this technology further. The utilization of conducting polymers in manufacturing membranes combining their electrochemical properties along with mechanical properties is of primary importance to enhance the efficiency of this system. In the present study blends of high impact polystyrene (HIPS) and polyaniline (PAni) were obtained with the aim of producing membranes for fuel cell. HIPS and PAni were dissolved in tetrachloroethylene, a common solvent for both materials. After dissolution, PAni was dispersed in an HIPS polymeric matrix. The membranes were molded on to glass plates using a laminator to keep thickness constant, and the solvent evaporated slowly for 24 h under room temperature. The amount of polyaniline used was 10 and 20 % weight. The electronic and structural properties were carried out using X-ray photoelectron spectroscopy (XPS), Thermogravimetric Analysis (TGA) Raman spectroscopy, Scanning electronic microscopic (SEM). The analysis indicate that PAni incorporation and its dispersion into the polymeric matrix modifies the membranes properties and show improvement in efficiency.
