Abstract
Official abstract text for this publication.
A bipolar plate and regenerative fuel cell stacks including the bipolar plates and membrane electrode assemblies (MEAs) alternately stacked. The bipolar plate comprises a plate main body formed of an electrically conductive material. The plate main body has a first surface and a second surface opposite the first surface. Each surface has reaction flow channels through which fluids pass. The reaction flow channels on the first surface have a plurality of ribs therebetween forming an interdigitate flow field pattern. The reaction flow channels on the second surface have a plurality of ribs therebetween forming an interdigitate flow field pattern or a flow field pattern different from an interdigitate flow field pattern, e.g., a serpentine flow field pattern.
First claim
Opening claim text (preview).
What is claimed is: 1. A frame for a bipolar plate, said frame comprising: a frame main body formed of an insulation material, said frame main body having a first surface and a second surface opposite the first surface; said frame main body having an aperture therethrough; and connection channels that are formed in the frame main body to connect to reaction flow channels in the bipolar plate; wherein the bipolar plate comprises: a plate main body formed of an electrically co…
