Leveraging Digital Advanced Manufacturing to Enable Polymer Electrolyte Fuel Cells With Ultrahigh Gravimetric Power Density

open access: yesAdvanced Energy Materials, EarlyView.
This study employs digital advanced manufacturing to develop lightweight, compact porous distributors as alternatives to conventional bipolar plates in PEM fuel cells. A graphene‐coated nickel foam achieves a power density of 1.52 W cm−2, while titanium‐based designs deliver lightweight solutions: an LPBF‐fabricated Gyroid lattice reaches 1.36 W cm−2 ...

Insight‐Guided Optimization of the Individual Steps in Ambient Slot‐Die‐Coated Perovskite Solar Cells

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This graphical abstract presents an integrated workflow for optimizing perovskite thin film fabrication by tuning ink rheology, refining processing parameters, and controlling crystallization. Viscosity control and process optimization precisely regulate wet film thickness and drying time, while crystallization directed by solvent additives yields ...
