The present invention relates to a separator plate in an electrochemical cell having a body with an electrically conductive first section having fluid flow fields with a plurality of flow channels formed therein and a second section 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. Further, the present invention contemplates methods to form such a separator plate.
A separator plate for use in a fuel cell stack, said plate comprising:
A method for forming a separator plate comprising forming first and second separator plate sections and joining said first and second separator plate sections into an integral body;
A separator plate for use in a fuel cell, said plate comprising:
