What are the design considerations for electrochemical reactors?

Key considerations: electrode selection (material, surface area, catalyst loading), electrolyte composition and conductivity, cell potential optimization (overpotential minimizes energy loss), current density (balance conversion rate vs efficiency), mass transfer to/from electrodes (agitation, flow-through electrodes), bubble management (gas evolution reactions), temperature control (affects kinetics and conductivity), and cell configuration (monopolar vs bipolar, flow-by vs flow-through). Scale-up maintains electrode spacing and current distribution. Applications: chlor-alkali, electrowinning, and emerging electrolysis.
