Abstract:
1. A fuel cell cassette comprising: a membrane electrode assembly, a fuel flow field, and an oxidant flow field, each component having at least one reactant manifold opening extending through the thickness thereof and at least one sealant manifold opening extending through the thickness thereof; wherein the membrane electrode assembly, the fuel flow field, and the oxidant flow field are assembled relative to each other such that the respective reactant manifold openings are aligned, and at least a portion of the respective sealant manifold openings are aligned; and wherein a resin is introduced into the peripheral edges of the membrane electrode assembly, the fuel flow field, and the oxidant flow field to encapsulate the periphery of the fuel cell cassette, and a sealant is introduced into the sealant manifold openings to enclose those reactant manifold openings which are not intended to deliver material to a particular flow field.
