Ionomers membrane, oxidant solubility

In Eqn (2.82), Cm is normally treated as the solubility of the oxidant in the ionomer membrane. The diffusion layer thickness 5o can be obtained using a rotating disk electrode technique, which will be given in a very detailed discussion in Chapter 5. The equivalent thickness of the ionomer membrane can be calculated according to the amount of ionomer applied in the electrode layer using the following equation ...
