State-of-the-art and developmental trends in platinum group metal-free cathode catalyst for anion exchange membrane fuel cell (AEMFC)

Mosaddek Hossen et al.

Summary: Non-platinum catalysts are essential for the economical application of AEMFC, and this review summarizes the advancements in the synthesis of different components and structures of catalysts. Thirteen catalysts have surpassed the peak power density threshold of 1000 mW.cm-2, including Metal-Nitrogen-Carbon (M-N-C), Bimetals-Nitrogen-Carbon (MM-N-C), Transition metal oxides (TMO), and non-metallic catalysts (NMC). The improvement in catalyst's porosity, surface area, conjugation of active sites, and synthesis procedures greatly affect the ORR activity and fuel cell performance.

High-performance radiation grafted anion-exchange membranes for fuel cell applications: Effects of irradiation conditions on ETFE-based membranes properties

Ana Laura G. Biancolli et al.

Summary: Anion-exchange membrane fuel cells (AEMFCs) are gaining attention in clean energy research for their high power output and cost reduction potential but face challenges in operational stability. The radiation-induced changes in polymer properties impact AEM mechanical performance and durability. Low absorbed doses and inert atmosphere during irradiation improve backbone stability and AEMFC durability.

Performance optimization of PGM and PGM-free catalysts in anion-exchange membrane fuel cells

John C. Douglin et al.

Summary: This study focuses on the performance of H-2-O(2) operando AEMFC using platinum group metal (PGM) and PGM-free catalysts. The as-synthesized PtRu/C catalyst showed significantly high performance and promising stability, reaching a peak power density of 1900 mW cm(-2). Additionally, AEMFCs using Pd-CeO2/C anodes paired with Pt/C and N-doped carbon cathodes achieved peak power densities of 890 and 537 mW cm(-2) respectively. The findings of this study provide insights into the development of AEMFCs using both PGM and PGM-free catalysts.

Crosslinked quaternary phosphonium-functionalized poly(ether ether ketone) polymer-based anion-exchange membranes

Mamta Kumari et al.

Summary: A series of mechanically robust and highly conducting crosslinked anion-exchange membranes were synthesized using quaternary phosphonium-functionalized poly(ether ether ketone) (QPPEEK) as the base polymer and poly(ethylene glycol) (PEG) as the crosslinker. Among different compositions, the QPPEEK-PEG 20 membrane showed the best properties with high hydroxide conductivity, good mechanical strength, and flexibility. This crosslinked membrane was chemically stable in alkaline environment and performed well in anion-exchange membrane fuel cell applications, indicating the potential of PEEK-based membranes for such applications.
