Research Description

Fuel Cell Electrolyte Membranes: The goal of our fuel cell membrane research is a cheap, easily processed, oxidatively stable, proton conducting membrane with high glass transition temperature and tailorable gas permeabilities. We have recently (with C. Cornelius & Cy Fujimoto at Sandia National Labs) developed a class of sulfonated polyarylenes (Figure 1) as polymeric electrolytes with excellent proton conductivity, thermal stability, mechanical properties and chemical stability.¹ The polymer electrolytes were prepared by a Diels-Alder polymerization followed by sulfonation. Hydrogen-oxygen fuel cells built with these membranes out-performed fuel cells built with commercially available membranes.
