| Summary: | Nowaday, oil fuel is main resources energy in the world. So, petroleum crisis was making a big problem which have to find out the alternative. One of the alternative is a fuel cell. Direct methanol fuel cell (DMFC) is a kind of fuel cell. Fuel cell construction generally consists of a fuel electrode (anode) and an oxidant electrode (cathode) separated by an ion-conducting membrane. In fuel cell construction, electrolite membrane play an important rule.The purpose of this research is synthesis chitosan and chitosan-tetraetilortosilicate (TEOS) membrane as a electrolite membrane for high temperature fuel cells. Result of this research showed that chitosan give 79,3% deasetilation degree. Beside that membrane chitosan-TEOS was succesfully synthesize under the suggestion condition. Existance of silica and silanol group in membrane matrix was prove by spectra IR. The membrane was named with CTSN, CTSN-0,5, CTSN-1, CTSN-1,5, and CTSN-2 code for easy of analysis. Resistance membrane toward temperatures as a one of the characterization membran reach to 1200C. The biggest value of ionic exchange was showed in CTSN-1,5 membrane as big as 0,114 meq/gram. The permeability measurement of methanol showed that the membrane have to modification. SEM analysis showed that membrane are porous. |
