Deadline: 21 Aug 2022

Alkaline water electrolyzers, for green hydrogen production, have been used at a large scale for about a century. Presently, a large scale-up in the number and size of industrial electrolyzers and electrolyzer plants is taking place, using modern materials and construction techniques. Their larger size and higher current densities require a partial re-design in which numerical simulations can be of great assistance.

Removing the large amounts of gas produced in stacks consisting of many cells, while avoiding large shunt currents, requires careful consideration of the geometry and dimensions of the manifold and channels. Inside each cell, the membrane-electrode and electrode-bipolar plate distances, and the elastic element properties influence the gas distribution, pressure drop, and energy efficiency in a yet unknown way.

In this project, in collaboration with McPhy, multiphysics multiphase simulations will be used to answer some of the design questions associated with the scale-up of future water electrolyzers.
