Abstract
The present invention concerns improvements in fuel cell fabrication. It concerns an improved, integrated and modular BSP/MEA/Manifolds, which facilitates single cell (module) leak and performance testing prior to assembly in a fuel cell stack as well as facilitating manufacturing and cost reduction.
Claims18
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.
