The thickness measurement of the Catalyst layers (CL) revealed for both a decrease as shown in Fig. 3. These thickness decrease along the gas path is mainly due to the H2 inlet/air outlet region in which the membrane degradation is favored [29]. WebMEA thickness, which is usually equal to the gap between the flow field plates under pressure) using the equation below: For example, a relative compression of 15 ± 5% is recommended when using Toray TGP-H-060 substrate.
