中文摘要	This study prepares novel metal mesh hybrid polymer composite bipolar plates for proton exchange membrane fuel cells (PEMFCs) via inserting a copper or aluminum mesh in polymer composites. The composition of polymer composites consists of 70 wt% graphite powder and 0-2 wt% modified multi-walled carbon nanotubes (m-MWCNTs). Results indicate that the in-plane electrical conductivity of m-MWCNTs/polymer composite bipolar plates increased from 156 S cm/sup -1/ (0 wt% MWCNT) to 643 S cm/sup -1/ (with 1 wt% MWCNT) (D.O.E. target >100 S cm/sup -1/). The bulk thermal conductivities of the copper and aluminum mesh hybrid polymer composite bipolar plates (abbreviated to Cu-HPBP and Al-HPBP) increase from 27.2 W m/sup -1/ K/sup -1/ to 30.0 W m/sup -1/ K/sup -1/ and 30.4 W m/sup -1/ K/sup -1/, respectively. The through-plane conductivities decrease from 37.8 S cm/sup -1/ to 36.7 S cm/sup -1/ for Cu-HPBP and 22.9 S cm/sup -1/ for Al-HPBP. Furthermore, the current and power densities of a single fuel cell using copper or aluminum mesh hybrid polymer composite bipolar plates are more stable than that of using neat polymer composite bipolar plates, especially in the ohmic overpotential region of the polarization curves of single fuel cell tests. The overall performance confirms that the metal mesh hybrid polymer composite bipolar plates prepared in this study are promising for PEMFC application. [All rights reserved Elsevier].
