Catalyst Layer Modifications for Enhanced Performance of Fluorine‐Free Proton Exchange Membrane Fuel Cells

open access: yesAdvanced 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.

An Exploratory Study on Graphene‐Based Hybrid Epoxy Coatings for Corrosion Resistance and Self‐Healing

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Corrosion of metallic process equipment in chemical, marine, and offshore industries leads to significant maintenance costs and safety concerns. Conventional epoxy coatings, though widely applied, often deteriorate under harsh conditions due to microcracking, moisture ingress and lack of self‐healing capability.
