A modular fuel cell cassette for use in assembling a fuel cell stack comprising a metal separator plate and a metal cell-mounting plate joined at their edges to form a hollow cassette. A fuel cell subassembly is attached to the mounting plate and extends through an opening in the mounting plate. The plates include openings to form chimney manifolds for supply and exhaust of fuel gas to the anode and air to the cathode. A conductive interconnect element extends from the fuel cell subassembly to make contact with the next cassette in a stack. The anode openings in the mounting plate and separator plate are separated by spacer rings such that the cassette is incompressible. A fuel cell stack comprises a plurality of cassettes, the mounting plate of one cassette being attached to, and insulated from, the separator plate of the next-adjacent cassette by a dielectric seal surrounding the interconnect.

A redox flow battery stack cell frame comprising a support frame and a monolithic bipolar plate integrated within the support frame is disclosed. The bipolar plate comprises a plurality of interdigitated flow channels on at least one surface. The support frame comprises an inlet manifold formed into a facing surface of the first side of the frame, the inlet manifold comprising fluid inlet distribution channels in a serpentine arrangement, each fluid inlet distribution channel aligned with a single inlet flow channel of the bipolar plate; and an outlet manifold formed into the facing surface of the opposing side of the frame, the outlet manifold comprising fluid outlet distribution channels in a serpentine arrangement, each fluid outlet distribution channel aligned with a single outlet flow channel of the bipolar plate. Redox flow battery stack cells and stacks comprising the stack cell frame are also disclosed.
