A fuel cell stack formed of repeating cell units is provided wherein each cell unit includes a fuel cell having an anode side and a cathode side; an anode side frame; a cathode side frame; a bipolar plate having an anode side interconnect adjacent to the anode side frame and a cathode side interconnect adjacent to a cathode side frame of an adjacent cell unit; a cathode side seal between the fuel cell and the cathode side frame; and an anode side seal between the fuel cell and the anode side frame, wherein at least one of the anode side interconnect, cathode side interconnect, anode side seal and cathode side seal are compliant.

Compliant stack for a planar solid oxide fuel cell

A power system for an aircraft includes a solid oxide fuel cell system which generates electric power for the aircraft and an exhaust stream; and a heat exchanger for transferring heat from the exhaust stream of the solid oxide fuel cell to a heat requiring system or component of the aircraft. The heat can be transferred to fuel for the primary engine of the aircraft. Further, the same fuel can be used to power both the primary engine and the SOFC. A heat exchanger is positioned to cool reformate before feeding to the fuel cell. SOFC exhaust is treated and used as inerting gas. Finally, oxidant to the SOFC can be obtained from the aircraft cabin, or exterior, or both.

Jet fuel based high pressure solid oxide fuel cell system

A standard phosphoric acid fuel cell power plant has its heat exchanger removed such that a higher temperature coolant flow can be directed from the system to the generator of an absorption chiller to obtain improved efficiency in the chiller. In one embodiment, the higher temperature coolant may flow directly from the fuel cell stack to the generator and then back to the high temperature coolant loop. Either a double effect absorption chiller or a single effect absorption chiller may be used.
