Furthermore, we showed how to navigate the critical trade-off between GDL properties. Prioritizing maximum GDL diffusivity and minimum contact resistance, which exhibit an inverse correlation, necessitates the utilization of low fiber concentration and low compression ratio. On the other hand, achieving maximum electrical and/or thermal conductivities while minimizing contact resistance require high fiber concentration accompanied by high compression ratio. These key findings would ultimately pave the way for autonomous optimization within GDL manufacturing processes.
