  • Anion-exchange membrane fuel cells (AEMFCs) face performance challenges due to CO2 in ambient air, which forms carbonate ions that reduce ionic conductivity. In this Perspective, the authors explore CO2 management strategies and discuss its potential stabilizing effects, offering insights to enhance AEMFC performance and stability.

  • Membranes formed from porous adsorbents can improve the economics of industrially difficult separations but require support materials that reduce gas permeance. Here an amorphous glassy foam membrane without a support is formed from ZIF-62 that shows high selectivity and permeance for CH4/N2 separations.

  • Microporous organic polymers (MOPs) are technologically important for low-dielectric materials, gas separation and gas-storage applications. A class of amorphous MOPs prepared by cycloaddition modification is shown to exhibit outstanding CO2 separation performance and super-permeable characteristics

  • Through-plane conductivity in anion-exchange membranes is beneficial for their use in fuel cells as it aids movement of ions from cathode to anode. Liu and colleagues use ferrocenium polymers and an applied magnetic field to orient ion channels appropriately and achieve improvements in stability by formation of magnetically induced mixed-valence states.

  • Proton exchange membranes with short-pathway through-plane proton conductivity are attractive for proton exchange membrane fuel cells. Here the authors align proton conducting channels orthogonal to the plane of composite proton exchange membranes using a magnetic field for improved fuel cell performance.

  • Most proton exchange membrane fuel cells are designed to operate within a temperature range of a few tens of degrees, but functioning in a broader range of conditions could be advantageous. Here the authors use ultramicroporous, phosphoric acid-doped membranes that allow fuel cell operation from −20 °C to 200 °C.

  • The suppressed Cl- transport under micropore confinement is a critical challenge. Here, authors report tailoring the pore chemistry of framework polymer membranes, which alters the interaction between Cl- and membranes and speeds Cl- transport, improving flow battery performance.

  • Rigidity, as seen in crosslinked polymers, and plastic processability are mutually exclusive properties. Here, the authors prepare a solution-processable conjugated microporous thermoset with permanent pores and demonstrate its application as a two-dimensional molecular sieving membrane for hydrogen separation.
