Abstract:
1. A modular fuel cell for assembly within a fuel cell stack comprising an array of fuel cells, comprising: a single bipolar separator plate; a flexible membrane electrode assembly; a flexible bond, seal or gasket interposed between said single separator plate and said flexible membrane electrode assembly; and wherein said flexible bond, seal or gasket seals the edge portions of said flexible membrane assembly to prevent the release of reactants from the fuel cell; a manifold for the delivery and removal of reactants and reactant products to and from the fuel cell reactive areas; and a bond interposed between said manifold and said separator plate, wherein said bond affixes said manifold to said separator plate and wherein said bond provides a seal between said manifold and said separator plate to prevent the release of reactants from the fuel cell; wherein said bipolar separator plate, membrane electrode assembly, manifold, flexible bond, and seal or gasket are arranged so as to form a single fuel cell comprising a sealed, integrated unit independently removable from the fuel cell stack.
