AbstrakDi era globalisasi ini, kebutuhan bahan bakar fosil semakin meningkat dan ketersediannya semakin menipis. Oleh karena itu, dibutuhkan bahan bakar alternatif seperti Proton Exchange Membrane Fuel Cell (PEMFC). Tujuan dari penelitian ini adalah membuat dan mengkarakterisasi membran komposit kitosan-sodium alginat dari rumput laut coklat (Sargassum sp.) terfosforilasi sebagai Proton Exchange Membrane Fuel Cell (PEMFC). PEM dibuat dengan 4 variasi perbandingan konsentrasi antara kitosan dengan sodium alginat 8:0, 8:1, 8:2, dan 8:4 (b/b). Membran komposit kitosan-sodium alginat difosforilasi dengan STPP 2N. Karakterisasi PEM meliputi: uji tarik, swelling air, kapasitas penukar ion, FTIR, SEM, permeabilitas metanol, dan konduktivitas proton. Berdasarkan hasil analisis tersebut, membran yang optimal adalah perbandingan 8:1 (b/b) dengan nilai modulus young sebesar 0,0901 kN/cm2, swelling air sebesar 19,14 %, permeabilitas metanol sebesar 72,7 x 10-7, dan konduktivitas proton sebesar 4,7 x 10-5 S/cm. Membran komposit kitosan-sodium alginat terfosforilasi memiliki kemampuan yang cukup baik untuk bisa diaplikasikan sebagai membran polimer elektrolit dalam PEMFC. Kata kunci: kitosan, sodium alginat, terfosforilasi, PEMFC  AbstractIn this globalization era, the needs of fossil fuel certainly increases, but its providence decreases. Therefore, we need alternative fuels such as Proton Exchange Membrane Fuel Cell (PEMFC). The purpose of this study is preparationand characterization of phosphorylated chitosan-sodium alginate composite membrane from brown seaweed (Sargassum sp.) as Proton Exchange Membrane Fuel Cell (PEMFC). PEM is produced with 4 variations of concentration ratio between chitosan and sodium alginate 8:0, 8:1, 8:2, and 8:4 (w/w). Chitosan-sodium alginate composite membrane phosphorylated with 2 N STPP. The characterization of PEM include: tensile test, water swelling, ion exchange capacity, FTIR, SEM, methanol permeability, and proton conductivity. Based on the analysis result, the optimal membrane is ratio of 8:1 (w/w) with the value of Young’s modulus about 0.0901 kN/cm2, water swelling at 19.14%, methanol permeability about 72.7 x 10-7, and proton conductivity about 4.7 x 10-5 S/cm. The phosphorylated chitosan-sodium alginate composite membrane has good potentials for the application of the polymer electrolyte membrane in PEMFC. Keywords: chitosan, sodium alginate, phosphorylated, PEMFC

A proton exchange membrane of poly (vinylidene fluoride) grafted onto poly (2-acrylamido-2-methylpropane sulfonic acid) (PVDF-g-PAMPS) was prepared as follows: acrylamido-2-methylpropane sulfonic acid (AMPS) was first added to a N-Methyl pyrrolidone (NMP) solution containing poly (vinylidene fluoride) (PVDF) that was modified with plain sodium silicate. Ammonium persulfate was then added as an evocating agent and PAMPS was directly grafted onto the PVDF that was modified with plain sodium silicate. The influences of AMPS contents on the proton conductivity and methanol permeability were studied. The results showed that AMPS is easily grafted into PVDF modified by Plain sodium silicate (Na4SiO4), with increasing of the content of 2-acrylamido-2-methylpropane sulfonic acid, the methanol permeability became large gradually of PVDF-g-PAMPS membranes was increased.

The polystyrene-poly(arylene ether sulfone)-polystyrene (PS-PAES-PS) coil-semirod-coil triblock copolymer was synthesized by the condensation reaction of PS-COCl and H2N-PAES-NH2 telechelic polymers. The reaction was facile characterized by high yields with a perfect control over the block lengths. Following a known reaction protocol it was possible to selectively sulfonate the PS block of the triblock copolymer that led to the sulfonated copolymer sPS-PAES-sPS. Studies on its proton conductivity and methanol permeability were carried out to evaluate its use as the proton exchange membrane in direct methanol fuel cells. Proton conductivity of the membranes was increased depending on the sulfonic acid group content in the sulfonated polymer. The membranes exhibited good dimensional and thermal stability, and low methanol permeability compared to Nafion 117.
