Ohmic and activation losses in a polymer electrolyte membrane water electrolyzer cell
Application ID: 139561
In a polymer electrolyte membrane water electrolyzer cell, hydrogen and oxygen gas is produced by electrolysis. The hydrogen and oxygen compartments are separated by a polymer membrane, that also acts as electrolyte.
This introductory tutorial computes the ohmic and activation losses in a membrane-electrode assembly (MEA) in a polymer-electrolyte membrane water electrolyzer. The model geometry is in 1D and comprises two porous transport layers (PTLs) and one membrane domain.
The exterior boundaries of the hydrogen and oxygen PTLs are assumed to be at equilibrium with fully humidified gas streams, and gas diffusion is assumed to be fast, hence no mass transport or momentum transfer is included in the model
