초록

A fuel cell is provided including a single sheet film or ribbon of any leh of a Polymer Electrolyte Membrane ("PEM") wherein the PEM is divided into regions or zones of varying electrical conductivity and ionic conductivity, allowing the elimination of endplates and/or a bipolar configuration. In this non bipolar arrangement, means are provided for distributing fuel to only one side of the PEM and oxidant to only the other side of the PEM so as to prevent mixing of the fuel and oxidant.
