<p>The reactant flow field on the cathode side of a fuel cell assembly is formed from a plate (12) made from carbon particles that are bonded together by a fluorocarbon polymer binder. The cathode reactant flow field is non-porous, and is hydrophobic due to the presence of the polymer binder. The carbon particles are preferably carbon flakes which pack together very tightly, and require only a minor amount of the polymer binder to form a solid plate. The plate will provide cathode reactant flow channels (14), will conduct electrons and heat and will minimize acid absorption in a fuel cell stack due to its hydrophobic nature.</p> |
