Ordered Nanostructural Engineering of Cathode Catalyst Layer With High Mass Transport Efficiency for High‐Performance Ultra‐Low Pt Loading Proton Exchange Membrane Fuel Cells

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
An ordered cathode catalyst layer with efficient mass transport capability was developed based on the ALD of Pt onto VACNTs for high‐performance ultra‐low Pt loading PEMFC. The order‐structured cathode catalyst layer (CCL) has been considered the most promising solution to construct low‐cost proton exchange membrane fuel cells (PEMFCs) with an ultra ...

Support‐Driven Hydrogen Migration Enhances Ammonia Decomposition in Direct Ammonia Protonic Ceramic Fuel Cells

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Enhanced hydrogen species migration enabled by FN/BZY catalyst mitigates intermediate accumulation and improves DA‐PCFC performance during ammonia decomposition. Ammonia, with its high hydrogen density and carbon‐free nature, serves as ideal fuel for direct ammonia protonic ceramic fuel cells (DA‐PCFCs).

One‐Step Synthesis of Si–Graphene Heterostructures via in‐Flight Gas‐Phase Mixing for High‐Capacity Silicon‐Rich Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A one‐step gas‐phase synthesis directly assembles amorphous Si nanoparticles with few‐layer graphene heterostructures via in‐flight mixing. Compositions with only 15 wt.% FLG deliver ~2800 mAh g−1 (Si + FLG) at 0.05 C and retain ~1400 mAh g−1 after 100 cycles at a high cycling rate of 1 C, enabled by a percolated, strain‐buffering graphene network that
