Title: Interconnect for fuel cell stack

Abstract

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.
