摘要：
Sulfonated chitosan (SCS) was prepared and characterized to be used in the preparation of poly electrolyte membranesinfuel cells (PEMFCs). The studied parameters were: sulfonating agents and their concentrations; reaction time; temperatures; and stirring rates. The characterizations of chitosan (CS) and SCS were investigated by 1HNMR, FTIR, XRD, TGA, and DTG. Degree of sulfonation (DS), ionic exchange capacity (IEC),andsulfurcontent(Sc)ofSCSwere71.256%,0.4502mmol/g,and1.447%,respectively,atoptimumsulfonatingconditionsof12hr,70oC,and600rpmbyusing4Msulfuricacid.ThewateruptakeoftheSCSmembranewas37.4%,andthemechanicalpropertieswere6.95MPaand14%fortensilestrengthand elongation at break, respectively.
