Fuel Cells, Volume 26, Issue 4, August 2026.ABSTRACT Gas diffusion layers (GDLs), a critical component in H2${\rm H}_{2}$/O2${\rm O}_{2}$ proton exchange membrane fuel cells (PEMFCs), are commonly treated with polytetrafluoroethylene (PTFE) for controlling hydrophobicity. However, the influence of the GDL's native microstructure on the final PTFE spatial distribution is still poorly understood ...

A New Electrode Paradigm Enabled by Co‐Axial Electrospinning
Small, Volume 22, Issue 46, 18 August 2026.Co‐axial electrospinning creates fuel‐cell electrodes with a division of function: ionomer cores to conduct protons and tailored catalyst‐containing shells for electrochemical reactions. This separation allows a paradigm shift in materials design and functional properties for the core and shell ionomers, targeting chemistries to be tuned independently ...
