Ultrastable and Phosphoric Acid-Resistant PtRhCu@Pt Oxygen Reduction Electrocatalyst for High-Temperature Polymer Electrolyte Fuel Cells

Zhao An,
Huanqiao Li,
Xiaoming Zhang
et al.

Abstract: With much enhanced fuel flexibility to overcome the shortcomings of hydrogen production and storage, high-temperature polymer electrolyte membrane fuel cells (HT-PEMFCs) are still facing challenges of activity loss of oxygen reduction electrocatalyst under the working circumstance of phosphoric acid (PA) electrolyte. Dissolution and leaching of metal component of PtM (M = Cu, Co, Ni•••) electrocatalysts is one of the key factors that degrade their initial resistance toward PA and hinder the accessing of activi… Show more
