Information

The default properties are based on [Toray2010]. The electronic mobility (μ) is based on the through-plane value of resistivity. The thermal conductivity is through the plane at room temperature.

For more information, please see the CaGDL model.

Extends from CaGDL (Cathode gas diffusion layer).
