ALEXANDRIA, Va., June 25 -- United States Patent no. 12,338,333, issued on June 24, was assigned to Rensselaer Polytechnic Institute (Troy, N.Y.).
"Elastic sulfonated styrene diene block copolymers" was invented by Chulsung Bae (Cohoes, N.Y.).
According to the abstract* released by the U.S. Patent & Trademark Office: "The electrochemical energy conversion system include an anode, a cathode, and a proton exchange membrane disposed between the anode and the cathode. The proton exchange membrane includes a polymer having a hard block polymer, a soft block polymer, and one or more hydrophilic functional groups attached to the soft block polymer. The glass transition temperature of the hard block polymer is higher than a glass transition tempe...
