The montmorillonite (MMT)/multi walled carbon nanotube (MCNTs)/sulfonated polyether ether ketone (sPEEK) nanocomposite membrane were prepared by a method of solution casting for fuel cells application.The MMT and MCNTs were modified with sodium sulfanilateand poly (styrene sulfonic acid) (PSSA), respectively. The proton conductivity of theas-prepared membranes containing 0.5wt.% PSSA grafted MCNTs (PSS-g-MCNTs) and 0.5wt.% sulfonatedmontmorillonite (sMMT) increased by 0.013 Scm−1compared to the plain sPEEK.The tensile strength and yield strength of which increased by 34.37MPa and 34.20MPa relative to the 1.0 wt.% PSS-g-MCNTs loaded sPEEK, which indicated that PSS-g-MCNTs and sMMT may generate a proton conducting cocontinuous networkwithin the SPEEK matrix.

Sulfonated polyether ether ketone (SPEEK) was utilized as a proton exchange membrane (PEM) in Microbial Fuel Cell (MFC). The SPEEK performance in producing electricity had been observed in MFC using wastewater and glucose as substrates. The MFC with catering and tofu wastewater produced maximum power density about 0.31 mW/m2 and 0.03 mW/m2, respectively, lower that of MFC with tapioca average power density of 39.4 W/m2 over 48 h. The power density boosted because of the presence of Saccharomyces cerevisiae as inoculum. The study using of S. cerevisiae and Acetobacter acetii, separately, were also conducted in with glucose as substrate. The MFC produced an average power densities were 7.3 and 6.4 mW/m2 for S. cerevisiae and A. acetii, respectively. The results of this study indicated that SPEEK membrane has the potential usage in MFCs and can substitute the commercial membrane, Nafion.Article History: Received: Juni 14th 2017; Received: Sept 25th 2017; Accepted: December 16th 2017; Available onlineHow to Cite This Article: Putra, H.E., Permana, D and Djaenudin, D.

ABSTRACTThis work presents the synthesis and characterization of a pearylated polysiloxane material (PAP) from a polycondensation reaction, followed by functionalization with HClSO3 by an electrophilic substitution reaction. According to the characterization techniques applied, a sulfonated pearylated polysiloxane was also obtained, (SPAP). The purpose of this sulfonated material is to obtain an ionomer able to be applied in hydrogen fuel cells of the proton exchange membrane kind (PEMFC). The reaction to produce the polysiloxane precursor was carried out with the commercial reagents: PhSiCl3, Ph2SiCl2 and Ph3SiCl in anhydrous THF at 75 °C and the SPAP material was obtained by sulfonation of the precursor with chlorosulfonic acid. PAP and SPAP were characterized by 1H, NMR for liquids, 29Si NMR for solids, IR-ATR, SEM, and cyclic voltammetry. The NMR 29Si spectra show that PAP and PAPS contain crosslinking regions due to PhSiCl3, growing chain zones due to Ph2SiCl2 and polymer termination zones due to Ph3SiCl, obtaining a mixture of siloxanes. The analysis by cyclic voltammetry indicates that by integrating the area under the curve of the adsorption peaks of H2, a value of 0.062 mC/cm2 is obtained, a value close to the commercial ionomer of Nafion®.
