Detailed Description

template<int dim>
class FuelCellShop::Layer::SGL24BA< dim >

This class defines a SGL-24-BA GDL, for which effective transport properties are constant.

Todo:: Effective electron and thermal properties are estimates. Better values need to be obtained from the literature for accurate use of this class. The values for the electron and thermal conducitivities should be added to the constructor (lines 26-34 in SGL_24_BA.cc)

Todo:: Premeability values also needed.
