Abstract
A laminated fluid flow field assembly for an electrochemical fuel cell comprises a separator layer and a stencil layer. The separator layer is formed of electrically conductive, substantially fluid impermeable sheet material. The stencil layer is formed of electrically conductive sheet material, and has a fluid inlet and at least one opening extending between its major surfaces and in fluid communication with the fluid inlet. The separator layer and the stencil layer are consolidated along one of their major surfaces. In operation, the separator layer and the stencil layer cooperate to form an open-faced channel for conducting pressurized fluid introduced at the fluid inlet.
