Anode‐Engineered Protonic Ceramic Fuel Cell with Excellent Performance and Fuel Compatibility

Abstract

Directly utilizing hydrocarbon fuels, particularly methane, is advantageous yet challenging in high-performance protonic ceramic fuel cells. In this work, this technological hurdle is well addressed by selective deposition of secondary electrocatalysts within the porous Ni-cermet anode. This novel strategy sheds light on the development of multifunctional porous structures for energy and catalysis applications.
