Anode gas diffusion layer FCSys.Regions.AnGDLs.AnGDL

Information

This model represents the anode gas diffusion layer of a PEMFC. The x axis extends from the anode to the cathode. By default, the cross-sectional area in the yz plane is 50 cm².

The default porosity (ε = 0.88) is that of SGL Carbon Group Sigracet® 24 BC GDLs. The porosity of a GDL may be lower than specified due to compression (e.g., 0.4 according to [Bernardi1992, p. 2483], although that reference may be outdated). The default thermal conductivity of the carbon (θ = U.m*U.K/(1.18*U.W)) represents a compressed Sigracet® 10 BA gas diffusion layer [Nitta2008]. The default electrical conductivity is also for Sigracet® 10 BA [SGL2007].

The default pore radius (32 µm) is for SGL 25 BC according to [Parikh2012].

Default assumptions (may be adjusted):

All of the species have the same temperature, even in different phases.

For more information, please see the Region model.

Extends from Region (Base model for a 3D array of subregions).
