Controlling the mechanical and transport properties of layer-by-layer films and electrospun mat composite membranes for fuel cell applications
… proton exchange membrane (PEM) has to have high protonic conductivity, low fuel crossover, and be mechanically and chemically stable. In particular, for direct methanol fuel cells and for high temperature (>100 °C), low relative humidity (< 60% RH) hydrogen fuel cells, the current industrial …

Transport and Structure in Fuel Cell Proton Exchange Membranes
… weight copolymers (IV ~ 1.16). Surprisingly, protonic conductivity of the two series was similar. Moreover, the methanol permeability of the low molecular weight copolymers was increased, resulting in lower membrane selectivity and decreased mechanical properties. The feasibility of converting …
