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.
Journal ArticleDOI
Pervaporation membranes in direct methanol fuel cells
TL;DR: In this paper, polybenzimidazoleolemic membranes have been used for direct methanol fuel cell applications and have been shown to have up to a 15-fold improvement over Nafion.
Journal ArticleDOI
Mechanism of Tetraalkylammonium Headgroup Degradation in Alkaline Fuel Cell Membranes
Shaji Chempath,Brian R. Einsla,Lawrence R. Pratt,Clay S. Macomber,James M. Boncella,Jonathan A. Rau,Bryan S. Pivovar +6 more
TL;DR: In this article, the effect of the medium and the water content on the calculated reaction barrier was discussed. But the authors focused on the effect on the reaction path of tetramethylammonium (TMA) head groups.
Journal ArticleDOI
The Chemical and Structural Nature of Proton Exchange Membrane Fuel Cell Properties
TL;DR: In this article, the key chemical and structural features of proton exchange membranes that impact properties critical for fuel cell applications are discussed, focusing on the fuel cell relevant transport properties of Proton conductivity, methanol permeability and water diffusion coefficient.
Journal ArticleDOI
Sulfonated poly(arylene ether sulfone) copolymer proton exchange membranes: composition and morphology effects on the methanol permeability
TL;DR: In this paper, the authors investigated the methanol permeability of directly copolymerized 4,4′-biphenol based disulfonated poly(arylene ether sulfone) copolymers.
