FUEL CELL SEPARATOR PLATE ASSEMBLY

摘要

A fuel cell separator plate assembly ( 20 ) includes a separator plate layer ( 22 ) and flow field layers ( 24, 26 ). In one disclosed example, the separator plate layer ( 22 ) comprises graphite and a hydrophobic resin. The hydrophobic resin of the separator plate layer ( 22 ) serves to secure the separator plate layer to flow field layers on opposite sides of the separator plate layer. In one example, at least one of the flow field layers ( 24, 26 ) comprises graphite and a hydrophobic resin such that the flow field layer is hydrophobic and nonporous. In another example, two graphite and hydrophobic resin flow field layers are used on opposite sides of a separator plate layer. One disclosed example includes all three layers comprising graphite and a hydrophobic resin.
