Abstract

Direct methanol fuel cell is one type of direct alcohol fuel cell, where methanol in liquid form enters the anode cell without going through reforming process. Methanol has the advantage of being relatively cheap and has high electrochemical activity. However, direct methanol fuel cells have several disadvantages, namely low efficiency (about 60%), slow methanol oxidation reaction rate, the occurrence of methanol cross over and also the price of the membrane used as an electrolyte membrane in direct methanol fuel cells. The procedure in this research are composite membrane fabrication; characterization and performance composite membrane are membrane functional group analysis; morphology of membrane analysis; density of membrane measurement; methanol permeability measurement; swelling membrane. The result from this research are based on FTIR analysis, The entire membrane has amino and carboxylic acid groups that are bonded to each other and have hydrogen bonds; based on SEM analysis, chitosan: sodium alginate membrane has good pore performance; the density of the membrane increases as the composition of sodium alginate increases. The highest of membrane density is 1.3676 g/mL at 5:2 w/w; there is no methanol crossover so that the membrane can answer the problems of conventional Nafion® membranes; Swelling methanol at 5:1 and 5:2 w/w have the same swelling value, which is 10; Composite membrane from chitosan – sodium alginate can be used as as a substitute for the nafion membrane in DMFC.
