We propose a novel idea to improve the surface properties of carbon-based Pt-free electrocatalysts in Polymer Electrolyte Membranes (PEMs) and Alkaline Fuel Cells (AFCs). Our concept is based on the addition of oxygenophilic and hydrophobic ionic liquids (ILs) to form a thin passivating layer at the triple point between the electrocatalyst–electrolyte–gas interface where the Oxygen Reduction Reaction (ORR) takes place.

亲氧离子液体促进无铂碳电催化剂中的氧还原反应

我们提出了一种新颖的想法,以改善聚合物电解质膜(PEMs)和碱性燃料电池(AFCs)中基于碳的无Pt电催化剂的表面性能。我们的概念基于增氧和疏水离子液体(IL),以在发生氧还原反应(ORR)的电催化剂-电解质-气体界面之间的三点处形成一个薄钝化层。
