Advanced 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 ...

Advanced Energy and Sustainability Research, EarlyView.Considerable improvement in the performance of fully‐hydrocarbon‐based fuel cells is necessary to replace and compete with Per‐ and polyfluoroalkyl substances‐containing fuel cells. Herein, a way to enhance the ionic conductivity of the catalyst layer (CL) by incorporating insoluble ionomer particles into the CL is presented.
