Nanopore Confinement of Electrocatalysts Optimizing Triple Transport for an Ultrahigh‐Power‐Density Zinc–Air Fuel Cell with Robust Stability

Metal–air fuel cells with high energy density, eco‐friendliness, and low cost bring significantly high security to future power systems. However, the impending challenges of low power density and high‐current‐density stability limit their widespread applications. In this study, an ultrahigh‐power‐density Zn–air fuel cell with robust stability is highlighted. Benefiting from the water‐resistance effect of the confined nanopores, the highly active...
