ABSTRACT:
Electrolyte migrates inter-cell in fuel cell stacks due to an electric potential gradient across the stack. This migration can be substantially inhibited with a graphite separator plate which has been laminated to the electrolyte reservoir plates of adjacent fuel cells with a fluoropolymer resin. In such an arrangement, the fluoropolymer resin forms an electrolyte barrier between the graphite separator plate while maintaining an electrically conductive pathway between the electrolyte reservoir plate and the graphite separator plate.
