LINQCELL GDL1500 | 1.5mm Carbon Plate

LINQCELL GDL1500 is a graphitized carbon plate, commonly used as a gas diffusion layer and electrode for fuel cells. Its through plane resistance is less than 13.5 mΩcm2. The thickness is 1.5mm and is measured at 50 kpa. This material has been successfully used in assemblies for hydrogen production electrolyzer components as a gas diffusion layer and electrode.

LINQCELL GDL1500 with a density of ±0.60 g/cm3 is a close, almost direct, alternative to the highly popular and discontinued Spectracarb 6060. Compared to it it has a resistivity of 90mΩ-cm instead of 100mΩ-cm. Shortly, we should be able to die cut circles and most designs that you might require.

Air permeability of LINQCELL GDL1500 was evaluated using the ISO 5636-5 standard test method. Using a sample area of 0.1 in2 and an air volume of 300 mL, the measured air passage times were 9.30 s, 9.45 s, and 8.88 s (average: ~9.2 s).
