Detailed Description

template<int dim>
class FuelCellShop::Geometry::PemfcMPL< dim >

This function generates a PEMFC grid including a membrane, gas diffusion, microporous, and catalyst layers.

The grid contains all material IDs and boundary IDs and default values are shown below in the generate_grid() function.

If you would like to create a cathode, an anode or an MEA without an MPL, simply set the thickness of the layers you do not want to use to zero. The program will automatically remove that domain from the computational mesh.

Default values:

Material ID:

Cathode GDL 2
Cathode MPL 3
Cathode CL 4
Membrane 5
Anode CL 6
Anode MPL 7
Anode GDL 8

Boundary ID:
Cathode GDL/BPP 1
Cathode GDL/Gas Channel 2
Cathode GDL/MPL 9
Cathode MPL/CL 10
Cathode CL/Membrane 4
Anode CL/Membrane 5
Anode CL/MPL 11
Anode MPL/GDL 12
Anode GDL/BPP 7
Anode GDL/Gas Channel 8
Symmetric 0
