Abstract
A separator plate in an electrochemical cell and method for making the same includes a body with an electrically conductive first section having fluid flow fields with a plurality of flow channels formed therein. A second section is provided adjacent to the first section that has a header area defining a manifold that supplies fluids to the flow fields of each fuel cell. The second section is non-conductive to prevent possible electrical interaction with any aqueous fluids of finite ionic conductivity present in the fuel cell, which may result in inefficient fuel cell operations.
