Computing Multiple Local Minimizers for the Topology Optimization of Bipolar Plates in Electrolysis Cells
arxiv(2024)
Abstract
In this paper we consider the topology optimization for a bipolar plate of a
hydrogen electrolysis cell. We use the Borvall-Petersson model to describe the
fluid flow and derive a criterion for a uniform flow distribution in the
bipolar plate. Furthermore, we introduce a novel deflation approach to compute
multiple local minimizers of topology optimization problems. The approach is
based on a penalty method that discourages convergence towards previously found
solutions. Finally, we demonstrate this technique on the topology optimization
for bipolar plates and show that multiple distinct local solutions can be
found.
