Lattice Boltzmann Pore-Scale Investigation of Coupled Physical-electrochemical Processes in C/Pt and Non-Precious Metal Cathode Catalyst Layers in Proton Exchange Membrane Fuel Cells

“…This method had a much higher resolution ($2 nm) which allows for a more detailed distribution of Pt particles when compared with previous studies [20][21][22][23]26,27,40]. In the present work, we follow this synthesis guided motivation.…”

“…In the literature, several reconstruction methods have been developed for Pt CLs including the Gaussian random field method proposed by Want et al [20,21], the sphere-based annealing method by Kim and Pitsch [22], and the random carbon sphere method by Lange et al [23,26,27]. Recently, Siddique and Liu [24] developed a reconstruction method based on the specific synthesis process used in fabricating a given CL structure.…”

“…Therefore, numerical simulations capable of spanning these length scales provide a promising method for gaining meaningful insights into the coupled electrochemical processes in a CL. Over the past two decades, numerical investigations of the Pt-based CL have progressed from ultra-thin interface models [17], to homogeneous models [18], to agglomerate models [19], and most recently to pore-scale models [20][21][22][23][24][25][26][27][28]. Each advancement corresponds to a higher resolution of the nanoscale porous structures at the cost of more complicated numerical models [19].…”

“…Porescale simulations can be used to improve the fundamental understanding of reactive transport processes in porous media. The importance of pore-scale simulations is reflected in the increasing number of studies about pore-scale studies of reactive transport phenomena in Pt-based PEMFCs [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36]. However, pore-scale studies related to NPMCs-based PEMFCs has not been reported.…”

“…The present study applies a pore-scale model to CLs to evaluate the effects of nanoscale structural characteristics on the macroscopic transport properties, thus improving the fundamental understanding of reactive transport processes in the nanostructures of CLs. While there are a number of pore-scale studies of mass transport in Pt-based CLs [20][21][22][23][24][25][26][27][28][29][30][31][32], there is no such study on NPMC CLs. Our pore-scale model will be applied to the reactive transport processes in both Pt CLs and NPMC CLs, representing the first such study on NPMC CL systems.…”
