TL;DR: In this article, a micro-scale numerical model is developed to predict the electrical contact resistance between BPP and GDL by simulating the BPP surface topology and the GDL structure and numerically determining the status for each contact spot.

TL;DR: In this article, the effects of assembly pressure and operating temperature and humidity on PEM fuel cell stack deformation, contact resistance, overall performance and current distribution were analyzed by advancing a model previously developed by the authors.

TL;DR: In this article, a sequential approach was developed to study the pressure effects by combining the mechanical and electrochemical phenomena in fuel cells, which showed that higher assembly pressure increases cell resistance to gas mass transfer, causes an uneven current density distribution, and reduces electrical contact resistance.

TL;DR: In this paper, a finite element-based structural and mass transfer model was developed by integrating mechanical deformation, mass transfer resistance, and electrical contact resistance to study the effects of assembly pressure and the fuel cell overall performance.
