Crown Ether As a Chemical Stabilizer for Enhanced Cerium Stability and Radical Scavenging in Proton Exchange Membranes

Autor: Tanya Agarwal, Siddharth Komini Babu, Allen Sievert, Andrew M Park, Tim Hopkins, Suresh Advani, Ajay Krishna Prasad, Rod L. Borup

Publikováno v: ECS Meeting Abstracts. :1521-1521

Nafion is one of the standard proton exchange membranes that serves as the electrolyte membrane in fuel cells. However, it has been found to chemically degrade over time due to the generation of harmful peroxide and hydroxyl radicals. Attack by such
