Publication number: 20130108944Abstract: A proton conducting copolymer electrolyte with competitive voltage versus current density characteristics and superior durability comprises a proton conducting hydrophilic domain comprising a sulfonated poly(phenylene) polymer, and a hydrophobic domain comprising a main chain comprising a plurality of bonded arylene groups wherein essentially all of the bonds in the main chain of the copolymer are carbon-carbon or, to a certain extent, carbon-sulfone bonds. More particularly, none of the bonds in the chains of the copolymer are ether bonds. Due to the absence of ether bonds, the copolymer electrolyte is less susceptible to degradation in solid polymer fuel cells.Type: ApplicationFiled: October 25, 2012Publication date: May 2, 2013Applicants: FORD MOTOR COMPANY, DAIMLER AGInventors: DAIMLER AG, FORD MOTOR COMPANY
