Dynamic Model-based Analysis of Oxygen Reduction Reaction in Gas Diffusion Electrodes
Dissertations in Series (Dissertationen in Schriftenreihe)
Abstract
In this work, the first simulation model of oxygen depolarized cathodes (ODC), which are silver catalyst-based gas diffusion electrodes, is presented that considers the phase equilibrium of the gas-liquid interface and structure-related inhomogeneities in electrolyte distribution. By means of the model it has been identified that mass transport of water and ions in the liquid phase is a crucial factor for electrode performance and how it is influenced by the electrode structure.
