Mixed topology optimization: A self-guided boundary-independent approach for power sources
概要
The shift towards more sustainable resources [1–3] has led to a
heightened emphasis on electrochemical technologies as an essential
element in the envisioned societies of the future that rely on renewable
energy [4]. Therefore, any improvement in the performance of these
devices not only has significant implications for the sustainability of
our energy systems and the reduction of greenhouse gas emissions but
also holds the potential to improve human lives by enabling greater
access to clean and reliable energy sources. Considering the pivotal role
played by the microstructure of porous media in governing transport
phenomena [5], the optimization of electrode composition has been
extensively studied to enhance the performance of electrochemical
devices such as batteries [6], fuel cells [7], and electrolyzers [8].
Parametric optimization, along with mathematical modeling, is commonly used to identify the best combination of constituents within an
electrode. For instance, in a study of polymer electrolyte membrane
fuel cells (PEMFCs) [9], researchers used mathematical optimization to
identify the optimal platinum loading, platinum to carbon mass ratio
(Pt/C), and ionomer to carbon ratio (I/C) with the aim of enhancing
cell performance. ...
