recordFC

Base constants and units that are well-scaled for fuel cell simulation and analysis

Extends from Base (Base constants and units).

Information

The values of this record result in the following values for the base SI units (besides cd = 1, which is the default):

  • A ≈ 1e-5 (⇒ 1e3 C ≈ 1)
  • K ≈ 8.617
  • kg = 1e4 (⇒ 0.1 g = 1)
  • m = 10 (⇒ 10 cm = 1)
  • mol ≈ 96.485 (⇒ 0.01036 mol ≈1)
  • s = 100 (⇒ 10 ms = 1)
which are well-scaled for the states and efforts of a single-cell PEMFC. Also, with these settings:
  • 10 m/s ≈ 1
  • 9.872e-5 atm ≈ 1

For more information, please see the documentation for the Units package.
