摘要：

Application of the diffusion-migration equation to batteries and fuel cells with mixed molten salt electrolytes indicates the likelihood of composition gradients of magnitude dependent on current density, electrode separation, initial electrolyte composition, interdiffusion coefficient, transference number, and electrode reaction. These gradients can progress to phase separation, to chronopotentiometric transition, or to the establishment of a steady state. © 1979, The Electrochemical Society, Inc. All rights reserved.
