High-Performing Unitized Regenerative Fuel Cell Using PGM-Free Bifunctional Catalysts from Waste-Derived Carbon

Abstract Unitized regenerative alkaline-exchange membrane fuel cells (UR-AEMFCs) are a promising technology for energy storage, attending to their ability to operate in both galvanic (FC) and electrolytic (WE) modes. However, their round-trip efficiency (RTE) is greatly dependent...

Ultra-Stable Zinc Nitroprusside Cathode Operating at High Potentials for Inexpensive, Simpler-to-Scale Sodium-Ion Batteries

Abstract Driven by the demand for low-cost and environmentally sustainable energy storage technologies, sodium-ion batteries (NIBs) have emerged as a promising alternative to lithium-ion batteries. Among the various cathode candidates, Prussian blue analogs (PBAs) stand out due t...
