The Electronic Conducting Phase node defines the governing equations for the electronic conducting (electrode) phase.

Note that the 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 Current Collector, Gas Diffusion Electrode or Gas Diffusion Layer nodes. The electronic conductivity, Electrical conductivity, σs (SI unit: S/m), used in the domain equations, is defined on these domains.
