A solid oxide fuel cell (SOFC) system includes high thermal conductivity materials such as copper to increase thermal energy transfer by thermal conduction. The copper is protected from oxidation by nickel electroplating and protected from thermal damage by providing oxidation resistant liners inside combustion chambers.

A gas separation unitfor permeating a gas out from a pressurized feed mixture includes an input manifold, an exhaust manifold,and a permeate assembly. The permeate assembly supports one or more permselective foilsover a hollow cavitysupported by a microscreen element. The microscreen element includes non-porous perimeter wallssupported on a frame surface and a porous central areasupported over the hollow cavity. A porous spacerdisposed inside the hollow cavity structurally supports the entire microscreen surface spanning the hollow cavity while also providing a void volume for receiving fluid passing through the porous central area and for conveying the fluid through the hollow cavity.

Membrane support module for permeate separation in a fuel cell

The invention provides a fuel cell stack including a layer of encapsulating material disposed about the separator plate, MEA, and reactant manifold, wherein the reactant manifold is bounded at least in part by the encapsulating material. The fuel cell stack also includes a first opening through the plate body to the first face from the second face, and an open channel in the second face extending from the opening toward a periphery of the plate. The invention also provides a fuel cell stack having a first face including an opening for passage of a reactant therethrough, a first reactant flow field defined thereon, and a first raised surface formed thereon substantially surrounding the opening. The first raised surface is configured and adapted to mate with a second surface on a face of an adjacent plate to create a flow obstruction for encapsulating material.
