Abstract
An edge manifold assembly conducts, introduces and receives reactant and coolant streams to and from an electrochemical fuel cell stack. The assembly comprises a plurality of manifold plates. Each of the fuel cells has a pair of manifold plates attached thereto. Each of the manifold plates has at least one manifold opening formed therein for containing a fluid and at least one channel formed therein for effecting fluid communication between the manifold opening and the fuel cell to which the manifold plate is attached.
