A method of making an interconnect for an electrochemical cell stack includes providing the interconnect, and creep flattening the interconnect prior to placing the interconnect into the electrochemical cell stack.

Methods and devices for preventing thermally-induced stress cracks in large footprint solid oxide fuel cell columns

A solid oxide fuel cell system and method, the system including a hotbox containing a fuel cell stack, a fuel supply configured to provide a fuel to the fuel cell stack, and a blower configured to provide air to the fuel cell stack. During a shutdown operation, the blower is configured to cool the fuel cell stack at a rate ranging from about 0.75&#xb0; C./min to about 3.0&#xb0; C./min, until the temperature of the fuel cell stack is reduced to a temperature at which oxidation of anodes of the fuel cell stack is substantially prevented.

SOFC system and method to decrease anode oxidation

A fuel cell assembly includes a fuel cell stack including a plurality of fuel cells, an incoming oxidizing gas flow path configured to deliver an oxidizing gas to the plurality of fuel cells, and a chromium-getter material located in the incoming oxidizing flow path. A fuel cell includes an electrolyte, a cathode electrode on a first side of the electrolyte, an anode electrode on a second side of the electrolyte, and a chromium-getter material on the cathode electrode.

Systems and methods for suppressing chromium poisoning in fuel cells

Various methods of treating a chromium iron interconnect for a solid oxide fuel cell stack and coating the interconnect with a ceramic layer are provided.

Coatings for SOFC metallic interconnects

A method of coating an interconnect for a solid oxide fuel cell includes providing an interconnect including Cr and Fe, and coating an air side of the interconnect with a manganese cobalt oxide spinel coating using a plasma spray process.

Coatings for metal interconnects to reduce SOFC degradation

A method of operating a solid oxide fuel cell (SOFC) system which contains a plurality of SOFCs having cermet anode electrodes includes operating the SOFC system above 760&#xb0; C. to generate electricity and intentionally oxidizing the cermet anode electrodes at a temperature of at least 760&#xb0; C. when the SOFC system stops operating to generate electricity.
