The Electrolyte Phase node defines the governing domain equations for the electrolyte phase.

Note that this node is added by default, and that you cannot alter the selection of the node by settings on the node itself. The node will be active on domains selected by Membrane, Separator, Gas Diffusion Electrode or Gas-Electrolyte Compartment nodes.

The Electrolyte conductivity, σl (SI unit: S/m), parameter will define how the current in the domain depends on the gradient of the potential. This section is unavailable if Solve for electrolyte phase potential is cleared in the interface top node.

A user-defined electrolyte potential (SI unit: V) can be entered here if Solve for electrolyte phase potential is cleared on the interface top node.
