Fast Irreversible Surface Reaction
This boundary node defines an irreversible reaction where the kinetics is so fast that the only factor limiting the reaction rate is the transport of a species to the reacting surface.
The node will set the Rate limiting species concentration to zero at the boundary, and balance the fluxes of the species participating in the reaction and the current densities according to the Stoichiometric Coefficients settings.
This feature is only available in a limited set of add-on products. See http://www.comsol.com/products/specifications/ for more details on availability.
