Abstract: High Resolution Image Download MS PowerPoint Slide This study integrates macromixing and micromixing methodologies to characterize an electrochemical reactor with a gas diffusion electrode (GDE) based on computational fluid dynamics (CFD) simulations validated by residence time distribution (RTD) data. It experimentally evaluates two types of GDEs for H 2 O 2 accumulation and uses the validated CFD model to evaluate the distribution of H 2 O 2 in the reactor. The tanks-in-series (T-I-S) model provides a qualitative understanding of the fluid’s macroscopic behavior, while the transition SST model analyzes the fluid’s microscopic dynamics and turbulence zones. The study reveals a significant convergence of current density, volumetric flow rate, and GDE type for H 2 O 2 production. The optimal experimental configuration (carbon/PTFE/fabric with Q = 50 L h –1 ) was evaluated through CFD simulations in the distribution of H 2 O 2 at different flow rates. These results improve our understanding of the hydrodynamics of the electrochemical reactor and offer prospects for optimizing the H 2 O 2 generation and accumulation processes.
