The dynamics of fuel cell coolant flow with charged nanoparticles were modeled using COMSOL Multiphysics. A computational fluid dynamics physicochemical model of the multi-phase coolant flow has been formulated.

For nanoparticles in the fluid, electrokinetic force, hydrodynamic force, and buoyancy forces have been taken into account for the prediction of electrodeposition rate onto channel walls. Electrochemistry, fluid mechanics, steric stabilization, and heat transfer are coupled in this model.
