Effect of polymer-coating on carbon blacks for Pt utilization efficiency of polymer electrolyte membrane fuel cells

Samindi Madhubha Jayawickrama et al.

Summary: In order to reduce the usage of Pt in polymer electrolyte membrane fuel cell electrocatalysts, improving the Pt utilization efficiency is crucial. This study investigates the effect of polybenzimidazole (PBI) wrapping on carbon blacks (CBs) to enhance Pt utilization efficiency, with HSA CBs showing a greater improvement compared to LSA CBs. The mechanism behind the improvement is mainly related to the micropore capping by PBI wrapping, which increases the electrochemical active surface area as well as the proton conductivity and O-2 diffusion.

Synergistically integrated phosphonated poly(pentafluorostyrene) for fuel cells

Vladimir Atanasov et al.

Summary: Phosphonated polymers have been proposed as anhydrous proton conductors for fuel cells, but anhydride formation lowers conductivity. By synergistically integrating phosphonated poly(pentafluorostyrene) and maintaining protonic conductivity above 200 degrees C, advanced fuel cells with peak power densities surpassing traditional materials have been achieved. This study presents a promising pathway for utilizing phosphonated polymers in high-performance fuel cells under hot and dry operating conditions.

On the stability of imidazolium and benzimidazolium salts in phosphoric acid based fuel cell electrolytes

Hongying Tang et al.

Summary: Polymers containing organic cations are promising materials for high temperature polymer electrolyte membranes due to their high PA retention and wider operation temperature range. However, the stability of these organic cations needs further investigation. By designing and preparing model cations, assessing their stability, and using a blend membrane with PBI and PA, significant progress has been made in developing durable high-performance HT-PEMs for green energy conversion.

NMR Quantification of Hydrogen-Bond-Accepting Ability for Organic Molecules

Mira Milic et al.

Summary: By utilizing F-19 and P-31 NMR spectroscopy, the hydrogen-bond-accepting abilities of over 100 organic molecules can be quantified using PFBA and PPA as probes. Analysis indicates that changes in NMR shifts can predict contributions to H-bond-accepting ability, and the binding of PFBA and PPA can predict electronic trends.

Enhancing oxygen reduction electrocatalysis by tuning interfacial hydrogen bonds

Tao Wang et al.

Summary: The proton activity at the electrified interface plays a crucial role in the kinetics of proton-coupled electron transfer reactions. By using a library of protic ionic liquids on platinum and gold interfaces, researchers have successfully enhanced the oxygen reduction reaction activity by up to fivefold, showing a volcano-shaped dependence on the pK(a) of the ionic liquid. This enhancement is attributed to strengthened hydrogen bonds between ORR products and ionic liquids with similar pK(a)s, leading to favorable PCET kinetics.
