A cross-flow interconnect and a fuel cell stack including the same, the interconnect including fuel inlets and outlets that extend through the interconnect adjacent to opposing first and second peripheral edges of the interconnect; an air side; and an opposing fuel side. The air side includes an air flow field including air channels that extend in a first direction, from a third peripheral edge of the interconnect to an opposing fourth peripheral edge of the interconnect; and riser seal surfaces disposed on two opposing sides of the air flow field and in which the fuel inlets and outlets are formed. The fuel side includes a fuel flow field including fuel channels that extend in a second direction substantially perpendicular to the first direction, between the fuel inlets and outlets; and a perimeter seal surface surrounding the fuel flow field and the fuel inlets and outlets.

Cross-flow interconnect and fuel cell system including same

A fuel cell system performance recovery method includes applying a DC current load pulse waveform to one or more of the fuel cells for a recovery period sufficient to desorb a contaminant from the one or more fuel cells.

Systems and methods of restoring fuel cell system performance

A fuel cell system and method, the system including power generating fuel cells disposed in a stack, each power generating fuel cell including an anode, a cathode, and an electrolyte, a sensing fuel cell including an anode, a cathode, and an electrolyte, and a fuel processor configured to purify a fuel provided to the power generating fuel cells and the sensing fuel cell. The anode of the sensing fuel cell is thinner than the anodes of the power generating fuel cells.

Fuel cell systems and methods for detecting fuel contaminants and hydrocarbon content

A buffer layer between an interconnect and an electrolyte of a solid oxide fuel cell, the buffer layer having a gradient in coefficient of thermal expansion (CTE), wherein the buffer layer minimizes electrolyte damage due to a difference in CTE between the interconnect and electrolyte.

Method of providing a functionally graded composite layer for coefficient of thermal expansion compliance in solid oxide fuel cell stacks and system components

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 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.
