Use the Positive Porous Electrode node to set up current balances for the electrode and the pore electrolyte in the lead oxide electrode, a material balance for the salt, and a mass balance for lead, lead oxide, and lead sulfate, using the porosity variable. In addition, the feature is also able to define the charge transfer reactions that take place in the lead oxide electrode.

See Negative Porous Electrode for all settings.

The difference between the Positive and Negative Porous Electrode nodes are the default values for some of the parameters, for instance of the Equilibrium Potential of the Porous Electrode subnode.
