Polymeric fuel cells based on proton exchange membranes (PEMs) are promising electrochemical devices for clean energy generation. A key factor in optimizing their performance lies in understanding the structural and mechanical behaviour of PEMs under varying temperature and humidity conditions. In this context, Dynamic Mechanical Analysis combined with Small- and Wide-Angle X-ray Scattering (DMA-SWAXS) provides a powerful approach to simultaneously probe nanostructural features—such as size, shape, and interfacial properties—and mechanical response.

This talk presents a comparative study of the nanostructure and mechanical properties of two PEMs, investigated using DMA-SWAXS at the ForMAX beamline at MAX IV (Lund, Sweden).
