Finite Element Simulations in Electrochemistry. 2. Hydrodynamic Voltammetry

A numerical strategy is reported based on the finite element method for simulating the mass transport limited current flowing at macro- and microelectrodes located within a rectangular channel cell. Specifically, simulations of a large planar, microband, and microstrip electrode are presented and the results compared to those predicted using alternative strategies. The finite element method is shown to be a flexible and efficient alternative to the previous strategies employed. The potential to extend finite element simulations to more complex geometries less suited to finite difference simulations is noted.
