Abstract
A composite plate () is formed in a mold () by placing one of two preforms () of between about 80 wt. % and about 85 wt. % flake graphite, balance polymer binder, into the mold and disposing a coolant tube array () thereon, depositing a powder () of the flake/polymer around the tube array, placing a second preform on the powder and a mold plunger () on the second preform, heating the mold to the melting temperature of the polymer under a pressure of 625 psi (4311 kPa), cooling the mold to the solidification temperature of the polymer while still under pressure, cooling the mold further, disassembling the mold, and removing the composite plate. The composite plate has reactant gas flow field channels () in major surfaces thereof, is devoid of any acid edge protection layer or film and is devoid of any acid impervious separator plate between either of the fuel cell reactant gas flow fields and the coolant tube array.
