A conduit assembly includes a dielectric tube having a first end and a second end, a first metal tube including a first flange coupled to the first end of the inner dielectric tube, the first flange including relief openings, a first dielectric ring coupled to the first flange, a second metal tube including a second flange coupled to the second end of the inner dielectric tube, the second flange including relief openings, and a second dielectric ring coupled to the second flange.

Dielectric conduit assemblies and methods of making thereof

A method of forming a fuel cell interconnect includes depositing a Cr alloy powder, sintering the Cr alloy powder, and repeating the depositing and the sintering to form the fuel cell interconnect. The Cr alloy powder may include a pre-alloyed powder containing from about 4 wt. % to about 6 wt. % Fe, and from about 94 wt. % to about 96 wt. % Cr.

Methods for manufacturing fuel cell interconnects using 3D printing

A fuel cell stack assembly includes a fuel cell stack column, and side baffles disposed on opposing sides of the column. The side baffles include side baffle plates containing at least one ceramic matrix composite (CMC) panel having at least one hole, and at least one denser ceramic element joined to the at least one CMC panel at the hole in the CMC panel.

Method for joining a ceramic matrix composite to dense ceramics for improved joint strength

Various embodiments of a reactant feed and return assembly, such as an anode splitter plate (ASP), are provided for facilitating reactant feed and exhaust flow in a solid oxide fuel cell (SOFC) stack system. Embodiments include a reactant feed and return assembly including at least a first portion formed of a chromium-based alloy, such as a chromium-iron alloy, having a similar coefficient of thermal expansion as other SOFC components and may therefore reduce internal stress in an SOFC stack. Methods for making an a reactant feed and return assembly comprising a chromium-based alloy are also provided.

Anode splitter plate and methods for making the same

Methods for fabricating an interconnect for a fuel cell stack that include providing a protective layer over at least one surface of an interconnect formed by powder pressing pre-alloyed particles containing two or more metal elements and annealing the interconnect and the protective layer at elevated temperature to bond the protective layer to the at least one surface of the interconnect.

Method of fabricating an interconnect for a fuel cell stack

Various embodiments include methods of fabricating an interconnect for a fuel cell stack. Methods for controlled pre-oxidation of an interconnect include oxidizing in a nitride-inhibiting environment to inhibit the formation of nitrides.

Thermal processing of interconnects

Various embodiments include interconnects for a fuel cell stack that includes a first support frame having a first surface that is configured to be secured to a first surface of a fuel cell. A gas flow separator section is secured to a second surface of the first support frame, opposite the first surface of the first support frame. A second support frame is secured to a second surface of a second fuel cell, opposite the first surface of the first fuel cell. The first and second support frames have a coefficient of thermal expansion (CTE) that substantially matches the CTE of the electrolyte material of the fuel cells, and the gas flow separator section has a CTE that does not substantially match a CTE of an electrolyte material of the fuel cells.

Interconnect for fuel cell stack

A method of making a solid oxide fuel cell (SOFC) includes providing a solid oxide electrolyte and depositing at least one electrode on the electrolyte by PVD, such as sputtering. A method of making an interconnect for a fuel cell stack includes providing an electrically conductive interconnect, and depositing a layer on the interconnect by PVD, such as depositing a LSM barrier layer by sputtering. The SOFC and the interconnect may be located in the same fuel cell stack.
