Interconnect for fuel cell stack

A metal interconnect for a fuel cell stack is formed from an electrically conductive metal sheet having at least four stamped slots through the metal sheet, and often many more than four slots. The stamped slots individually extend lengthwise parallel to the direction of fluid flow during operation of the fuel cell stack assembly and are disposed on the metal sheet in a pattern extending parallel and perpendicular to the direction of fluid flow, so as to define at least one metal strip portion between adjacent slots extending parallel to the direction of fluid flow and at least one metal strip portion between adjacent slots extending perpendicular to the direction of fluid flow. The metal strip portion(s) include portions of reduced thickness that allow for fluid flow between adjacent slots and portions of greater thickness that provide discrete locations of electrical connection between the separator plate fuel cell electrode.

Multiple stack fuel cell system

A fuel cell system is disclosed comprising a plurality of fuel cell modules including a sealed planar fuel cell stack, the stack including internal manifold channels for transport of fuel and air to fuel cells within the stack and transport of tail gas and spent air away from fuel cells within the stack. Each of the fuel cell stacks is mounted on a stack footprint area of a top member of a base manifold. The base manifolds are configured to allow for interconnection of a number of fuel cell stack modules to provide a fuel cell system capable of producing power outputs that otherwise would have required large surface area cells or stack with a large number of cells.

Multiple stack fuel cell system with shared plenum

A multi-stack fuel cell system is disclosed where multiple fuel cell stacks can be efficiently connected together. The fuel cell system includes a plurality of fuel cell modules include a sealed planar fuel cell stack that has internal manifold channels for transport of fuel and air to fuel cells within the stack and transport of tail gas and spent air away from fuel cells within the stack. Each of the fuel cell stacks is mounted on a base manifold, and the base manifold has side openings in fluid communication with the stack internal manifold channels. The side openings on the base manifold are configured so that the modules can be efficiently connected together.
