Numerical calculation of secondary current distribution in a two-dimensional electrochemical cell with a non-uniform resistive electrode H. Kawamoto Manufacturing Engineering Laboratory, FUJI XE#OX Co., IW. 22%4 #on#o, E6mo-a/t2, Kanagawa 243-04, Japan ABSTRACT A new numerical method has been developed to calculate secondary current distri- bution in electrochemical cells. The method is applicable in arbitrary two-dimen- sional systems which include thin, non-uniform, and/or anisotropical resistive elec- trodes with nonlinear polarization kinetics such as the Butler-Volmer polarization at electrolyte-electrode interfaces. The calculation uses a double iterative method employing the boundary element method in the electrolyte region and the uniform resistive electrode region and the finite element method in the non-uniform and/or anisotropical resistive electrode region. Parametric calculations for a corner elec- trode were performed to demonstrate the present met
