Some conditions are taken from the outer environment model. In particular,
environment.T is used as the initial temperature
throughout the cell, the temperature at each inlet, and the
exterior temperature of each end plate in the yz plane.environment.p is used as the initial pressure
throughout the cell and the pressure at each outlet.environment.RH is used as the initial relative
humidity throughout the cell.environment.psi_O2_dry is used as the dry-gas
concentration of O2 at the cathode inlet.
