Summary: The constant increase in global emission standards has led to the importance of fuel cell (FC) technology. Research in the past two decades has focused on developing more active catalysts for high-temperature polymer electrolyte membrane fuel cells (HT-PEMFC) and improving their durability. Two main approaches have been suggested: alloying platinum (Pt) with low-cost transition metals to reduce Pt usage, and developing novel catalyst supports to enhance metal particle anchoring and inhibit corrosion phenomena. This comprehensive review details the recent development of platinum group metal (PGM) and platinum group metal free (PGM-free) catalysts, as well as alternative carbon (C) supports for HT-PEMFCs.

Summary: This study presents an innovative PBS-GC system to assess the mechanical fatigue of commercial Nafion membranes under PEMFC operating conditions. Results indicate that hydrogen gas is more effective in inducing mechanical losses, confirmed by changes in proton conductivity and hydrogen permeability after aging tests. The developed system demonstrates the capability of screening and characterizing membrane candidates in a relatively short period of time.

Summary: In this study, we found that ceria weakens the Pt-surface oxophilicity, improves the durability of polymer electrolyte membrane fuel cells (PEMFCs), and can be finely tuned through nanostructuring. Among various ceria nanostructures, tubular ceria nanoarchitectures enable the most potent interaction between Pt and Ce, resulting in superior antioxidant therapeutic efficacy and durability.
