A study on high proton conducting polymer electrolytes pore-filling membranes with lower methanol cross-over for direct methanol fuel cell |
| 초록 |
High proton conducting polymer electrolyte pore-filling membranes consisting of whole hydrocarbon materials were prepared with lower methanol cross-over against commercial perfluorinated polymer membranes and characterized on the properties for applying to direct methanol fuel cell. Various porous polyolefin substrates were used for preparation of the pore-filling membranes. The proton conductances of the polymer electrolyte membranes prepared in this research were dependent on the composition ratio of an electrolyte monomer and crosslinking agents used for polymerization. Methanol cross-over permeabilities of the prepared membranes was 10 30 times lower than those of the compared commercial membranes even though their proton conductances were higher than those of the compared commercial membranes. |
