| Research Abstract |
Anion conductive aromatic multiblock copolymers containing ammonium-substituted fluorene groups, were synthesized The quaternized multiblock copolymers produced ductile, bendable, and transparent membranes. A well-controlled multiblock structure was responsible for the developed hydrophobic/hydrophilic phase separation and interconnected ion transporting pathway, as confirmed by scanning transmission electron microscopic observation. The ionomer membranes showed high hydroxide ion conductivities in water. The durabilities of the membranes were evaluated under severe, accelerated-aging conditions, and minor degradation was recognized. A noble metal-free direct hydrazine fuel cell was operated with the QPE membrane at 80 degree C. High maximum power density was achieved.
