Two-phase mass transfer in porous transport layers of the electrolysis cell based on a polymer electrolyte membrane: Analysis of the limitations
Original language description
Various regimes of gas–liquid flows in porous transport layers/current collectors and their effect on the performance of a model electrolysis cell based on a polymer electrolyte membrane (PEM) are described, based on mathematical simulation. The latter is based on the utilization of a standard description of the two-phase transfer of liquid water, water vapor, and noncondensable gasses in porous media. Numerical calculation with usage of model developed for porous transport layers of an electrolysis cell allowed the determination of the optimal operational parameters for the basic components of the electrolysis cell in dependence of their parameters. Operating conditions causing critical modes of mass transport were identified as well. This study reports of the results of a numerical analysis and discuss consequences for the components of the PEM-based electrolysis cell selection and on its electrical characteristics. © 2021
