Detailed Description

Class characterizing a carbon black support.

This material is commonly used in catalyst layers and micro-porous layers.

There are many types of carbon black used in fuel cells such as VulcanXC, Ketjen black, graphatized Ketjen black and HISPEC. Each one of these carbons have different densities and bulk propeties. This class provides an example for further development of other catalyst support objects. Note that in this case the propeties of the material can be modified in the input file. This is done in order to allow for investigation of different properties.

Parameters that can be specified in the input file for this class are as follows:

subsection Fuel cell data
  subsection Materials
    subsection Carbon Black
      set Density [g/cm^3] = 2.0
      set Electrical conductivity [S/cm] = 88.84  # Electrical conductivity of a group of particles packed to have 0% porosity
      set Thermal conductivity [W/(cm-K)] = 1.0
    end
  end
end

Usage Details:

As with most routines you need to first declare_parameters, then set_parameters (only if using optimization/parameter estimation), then initialize. After this the class is ready for use.

See for example FuelCell::OperatingConditions class for more details.

Constructor & Destructor Documentation

FuelCellShop::Material::CarbonBlack::CarbonBlack

(

const bool

)

PROTOTYE Constructor.

Warning

For internal use only.

FuelCellShop::Material::CarbonBlack::~CarbonBlack

(

)

Destructor.

FuelCellShop::Material::CarbonBlack::CarbonBlack ( )

private

Constructor The constructor initialize parameters using the default values.

This is so that if I do not want to call declare_parameters and initialize, I can still use the routine with the hard coded values.

privatevirtual

Member function used to change the values in the parameter file for a given list of parameters.

• name_dvar should ideally contain the string as it would appear in the input parameter file.
• value_dvar contains the value that the variable should be set at.
• param is the ParameterHandler that contains all the information that has been read from file.

List of available std::string that can be changed, i.e. name_dvar are given below:

• "electrical_conductivity_carbon" : electrical conductivity [S/cm] of carbon black support material.
• "thermal_conductivity_carbon" : thermal conductivity [W/(cm-K )] of carbon black support material.
• "density_carbon" : density [gm/cm^3] of carbon black support material.
