“…The literature presents a range of methodologies for investigating and ensuring the optimum compression ratio for fuel cells [8,9,22] and methods for identifying the uniformity and its effect on performance [10,11,15,16]. There are also some works which develop novel endplate structures and designs to improve uniformity [23,24].…”

“…Until recently, the main technique used to determine the GDL structure was scanning electron microscopy (SEM), frequently coupled with energy dispersive X-ray spectroscopy (EDS) analysis. SEM is useful in obtaining surface structural data, layer thickness, 'smoothness' of different interfaces, PTFE bonding, and fibre orientation, but fails to reveal the porosity and internal structure [5,6,[15][16][17][18][19][20][21][22]. Micro and nano X-ray computed tomography (CT) are non-destructive methods that can achieve sufficiently high resolution for the imaging of carbon fibres, which typically have diameters between 5 and 10 m, and they have been increasingly used to characterise GDLs [7,19,[23][24][25][26].…”
