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
