B‐Site Multi‐Element Micro‐Doping Engineered Air Electrodes With Fast Oxygen Kinetics for Reversible Protonic Ceramic Electrochemical Cells

Advanced Science, EarlyView.
Mo‐tuned multi‐element micro‐doping regulates redox chemistry, oxygen nonstoichiometry, hydration, and interfacial kinetics in PBSCF‐derived air electrodes for reversible protonic ceramic electrochemical cells. The cell with optimized PBSCFMNM03 air electrode delivers 1.10 W cm−2 in fuel cell mode and 1.88 A cm−2 at 1.3 V in electrolysis mode at 650 °C,

Hydrogen Production from Ammonia Electrochemical Cracking

Advanced Science, EarlyView.
NH3 electrochemical cracking (e‐cracking) is a complementary technique to centralized thermal cracking for releasing H2 from NH3. In this article, we review recent advances in catalyst development for these cracking techniques and conduct a techno‐economic analysis (TEA) to evaluate the economic feasibility of e‐cracking.

Dual‐Functional Membranes With Interfacial MXene/PFSA Nanoarchitectures for Low Hydrogen Permeation in Water Electrolysis and Reduced Vanadium Ion Crossover in Flow Batteries

Advanced Science, EarlyView.
A PFSA/MXene composite membrane is developed for both PEMWE and VRFB applications. MXene incorporation simultaneously enhances proton conductivity and suppresses hydrogen/vanadium crossover. The interaction between MXene functional groups and PFSA's –SO3H reduces the proton diffusion barrier via hydrogen‐bonding networks, while the disordered ...
