| 英文摘要 | we reconstruct a proton exchange membrane fuel cell (pemfc) catalyst layer (cl) and a non-woven carbon paper gas diffusion layer (gdl) by specially-designed stochastic methods. the reconstructed microstructures evidently distinguish all the participating components in the composite gdl/cl. characterization analyses with respect to the reconstructed gdl/cl give important structural properties such as geometrical connectivity of an individual phase, pore size distribution, and volume-specific interfacial area. self-developed lattice boltzmann (lb) models are established to calculate effective transport physical properties including effective thermal/electric conductivity and effective species diffusivity of the reconstructed gdl/cl, and permeability of the reconstructed gdl. accordingly, we obtain tortuosity values for pore or solid phase in the reconstructed gdl/cl. copyright (c) 2014, hydrogen energy publications, llc. published by elsevier ltd. all rights reserved. |
