TL;DR: The research focuses on the durability of polymer electrolyte fuel cells (PEFCs), in particular, membrane degradation, and he has been involved in NEDO R&D research projects on PEFC durability since 2001.

TL;DR: Devising systems that can conduct protons with little or no water is perhaps the greatest challenge for new membrane materials, and new membranes that have significantly reduced methanol permeability and water transport (through diffusion and electro-osmotic drag) are required for automotive applications.

TL;DR: In this paper, a biphenol-based wholly aromatic poly(arylene ether sulfone)s containing up to two pendant sulfonate groups per repeat unit were prepared by potassium carbonate mediated direct aromatic nucleophilic substitution polycondensation of disodium 3,3′-disulfonate-4,4′-dichlorodiphenylsulfone (SDCDPS), 4, 4′-dimethylactamide (DCDPS).

TL;DR: A review of the fundamental scientific principles underpinning the operation of polymers for gas separations, including the solution-diffusion model and various structure/property relations, is presented in this paper.

TL;DR: In this paper, the authors summarized the nature of the global water problem and reviewed the state of the art of membrane technology and identified existing deficiencies of current membranes and the opportunities to resolve them with innovative polymer chemistry and physics.
