Abstract
A fuel cell stack includes a plurality of fuel cells, each of which includes a membrane electrode assembly and a water transport plate, or a fluid flow plate fabricated from graphite. This plate and optionally a separator plate are held in assembled relationship with one another and with the membrane electrode assemblies by a fluoroelastomeric adhesive/sealant that is also coated on the external edges of these components to provide a water-tight seal to better contain the coolant fluid in the form of water provided in the fuel cell stack.
