ABSTRACT:
A flexible flow field separator includes a substrate layer formed of a flexible material and having first and second surfaces. A structured flow field pattern is defined on the first surface of the substrate layer. The structured flow field pattern defines one or more fluid channels. The separator includes a first layer formed of one or more metals and disposed on the first surface of the substrate layer. The first layer is formed of an electrically conductive material. The separator further includes a second layer disposed on the second surface of the substrate layer. The second layer is formed of a flexible electrically conductive material. The first layer contacts the second layer at one or more locations to define an electrical connection between the first and second layers.
