제목: Materials Interface Engineering for Membrane-Electrode-Assembly from Hydrogen Fuel Cell to Water Electrolyzer

내용: Advances in fuel cell and water electrolyzer are urgently needed to increase the performance and utilization of hydrogen and reduce the cost of electrochemical conversion systems. Polymer membrane and noble metal nanomaterial electrodes are the core components to produce the electrochemical reaction and the rapid progress in their development has increased its electrochemical-power conversion efficiencies and lifetime. Recent research and application activities include high performance Pt or Ir alloy catalysts, thin film nanostructured electrocatalyts, durable catalyst support, polymer composite membrane, and radical scavengers. Furthermore, 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.
