(545c) Materials Interface Engineering for Membrane-Electrode-Assembly from Hydrogen Fuel Cell to Water Electrolyzer

Advances in hydrogen fuel cell and water electrolyzer are urgently needed to increase the performance and reduce the cost of electrochemical conversion and utilization of hydrogen. Polymer membrane and catalyst electrodes are the core components to produce the electrochemical reaction and rapid progress in their development has increased its electrochemical-power conversion efficiencies and lifetime. Recent research and application activities include high performance noble metal alloy catalysts, thin film nanostructured electrocatalysts, durable catalyst support, polymer composite membrane, radical scavengers and oxygen-permeable ionomers. Moreover, the nanometer and micrometer scale interfaces in the membrane-electrode assembled layers are crucial for the scalable and sustainable electrochemical processes. In this talk, our recent results from these activities will be presented.
