연료전지용 Poly(styrene sulfonic acid)를 갖는 Poly(2,6-dimethyl-1,4-phenylene oxid)의 합성

Synthesis of Poly(2,6-dimethyl-1,4-phenylene oxide) containing Poly(styrene sulfonic acid) for Fuel Cell

The development and improvement of advanced fuel cell systems is a major topic of current research, since fuel cells are considerably more efficient than other energy converters$^1$. In proton exchange membrane fuel cell and direct methanol fuel cell the polymer membrane represents a key component. The membrane materials fulfill complex requirements. It has to combine electrochemical stability, workability, high ionic conductivity, low permeation of the reactants (methanol etc.) (omitted)
