Proton exchange membrane fuel cell for bipolar separator plate as increased water permeability relative to electronic conductivity; crush strength of plate; functionality of the plate to its ability to maintain water absorption capabilities and increased thermocycling between frozen and thawed state

摘要

A gas impervious bi-polar separator plate for a proton exchange membrane fuel cell having at least one electronically conductive material in an amount in a range of about 50% to about 95% by weight of the separator plate, at least one resin in an amount of at least about 5% by weight of the separator plate, and at least one hydrophilic agent, where the electronically conductive material, the resin, and the hydrophilic agent are substantially uniformly dispersed throughout the separator plate.
