This member function is used to create an object of type gas diffusion layer.

Warning
This class MUST be redeclared in every child.

Reimplemented from FuelCellShop::Layer::CatalystLayer< dim >.

template<int dim>
virtual void FuelCellShop::Layer::HomogeneousCL< dim >::current_density ( std::vector< double > &  )
virtual

This member function will use a FuelCellShop::BaseKinetics class in order to compute the current density production in the CL.

Reimplemented from FuelCellShop::Layer::CatalystLayer< dim >.

Referenced by FuelCellShop::Layer::HomogeneousCL< dim >::current_density().

Here is the caller graph for this function:

template<int dim>
virtual void FuelCellShop::Layer::HomogeneousCL< dim >::current_density ( std::vector< double > &  current,
std::vector< double > &  effectiveness 
)
inlinevirtual

This member function computes the current density production in the CL.

First argument is current density, and second is effectiveness, at all quadrature points in the cell. Since this is a macro-homogeneous layer, effectiveness is filled as 1.0
