Porous Matrix Adsorption/Desorption Reaction
Use this node to model non-faradaic reactions on the porous electrode particle surface, for instance hydrogen adsorption/desorption in a NiMH battery.
The Porous Matrix Adsorption/Desorption Reaction can be added as a subnode to a Porous Electrode parent node.
Enter values or expressions for the Rate expression k (SI unit: mol/(m2·s)) of the surface reaction and the stoichiometric Coefficient vs (dimensionless) of the intercalating species for this reaction. The Active specific surface area av (SI unit: 1/m) will only have an impact on post precessing of the volumetric source variable (mol/(m3·s)) of the intercalating species.
