Novel sulfonated N-heterocyclic poly(aryl ether ketone ketone)s with pendant phenyl groups for proton exchange membrane performing enhanced oxidative stability and excellent fuel cell properties

Qian Liu et al.

Summary: Novel sulfonated poly(bis-phthalazinone ether ketone ketone)s containing pendant phenyl moieties (SP-BNPs) exhibit excellent properties, including high proton conductivity, tensile strength, and superior oxidation stability compared to other sulfonated membranes. The introduction of phthalazinone units and sulfonated pendant phenyl groups effectively improves membrane performance.

Development of a High-Performance Proton Exchange Membrane:From Structural Optimization to Quantity Production

Weisheng Yu et al.

Summary: This study presents a facile synthesis approach for producing low-cost and high-performance proton exchange membranes (PEMs) used in hydrogen fuel cells. The prepared PEM breaks the trade-off between thermal-dimensional stability and proton conductivity by utilizing a hierarchical polymer structure consisting of flexible ionic side-chains anchored onto a twisted rigid backbone. Microscale topology structure analyses and molecular dynamics simulations reveal the formation of well-connected proton nanochannels through self-assembly of the hydrated ionic groups. Moreover, the PEM can be produced in large quantities using a pilot-scale production line and exhibits excellent fuel cell performance under low relative humidity conditions.

Porous gC3N4-Gd2Zr2O7 enables the high-temperature operation of Nafion membranes in polymer electrolyte fuel cells over 500 hours

Mohanraj Vinothkannan et al.

Summary: This study presents the use of carbon nitride-gadolinium zirconium oxide (gC(3)N(4)-Gd2Zr2O7) as an additive to improve the power density and lifetime of Nafion in high-temperature polymer electrolyte fuel cells (HT-PEFCs). The Nafion/gC(3)N(4)-Gd2Zr2O7 composite membrane exhibits high water uptake, oxidative stability, and thermomechanical stability, resulting in significantly higher power density and lower voltage decay compared to commercial Nafion and pristine Nafion membranes. This research provides valuable insights into the development of advanced Nafion composite membranes for HT-PEFCs.

Superacid sulfated SnO2 doped with CeO2: A novel inorganic filler to simultaneously enhance conductivity and stabilities of proton exchange membrane

Lili Liu et al.

Summary: By compositing with superacids of sulfated SnO2 and SnO2-xCeO(2), the trade-off between proton conductivity and stabilities of sulfonated poly(aryl ether sulfone) (SPAES)-based proton exchange membranes is broken, resulting in composite membranes with excellent performance. The superacids in the composite membranes provide additional active sites and proton-conducting channels, leading to higher water absorption and proton conductivity compared to the control membrane.

Durability enhancement of proton exchange membrane fuel cells by ferrocyanide or ferricyanide additives

Xin Liu et al.

Summary: The introduction of ferrocyanide-ferricyanide (Fc (II)-Fc (III)) redox cycle has been found to significantly enhance the chemical stability of proton exchange membranes (PEMs), leading to improved durability and longevity in proton exchange membrane fuel cells (PEMFCs). Additionally, the incorporation of Fc (II)/Fc (III) species not only enhances the performance of composite membranes, but also increases proton sites, thereby improving conductivity and power output.

Proton conductors for heavy-duty vehicle fuel cells

Craig S. Gittleman et al.

Summary: In the short term, stability of proton exchange membranes must be ensured, achieving stable conductivity of proton conductors under hot and dynamic conditions is desirable in the mid-term, and in the long term, high thermal stability and water tolerance are targeted to enable the utilization of high energy density liquid fuels.
