Filed:

Nov 15, 2012

Appl. No.:

13/677836

Inventors:

Bloom Energy Corporation - Sunnyvale CA, US
Eric Petersen - San Jose CA, US
Mina Touma - Sunnyvale CA, US
Richard Stephenson - Sunnyvale CA, US

Assignee:

BLOOM ENERGY CORPORATION - Sunnyvale CA

International Classification:

H01M 8/04
H01M 2/16
H01M 8/00
H01M 2/14

US Classification:

429460, 429468, 429508, 429535, 429509

Abstract:

A solid oxide fuel cell (SOFC) stack including a plurality of SOFCs and a plurality of interconnects. Each interconnect is located between two adjacent SOFCs, and each interconnect contains a Mn or Co containing, electrically conductive metal oxide layer on an air side of the interconnect. The SOFC stack also includes a barrier layer located between the electrically conductive metal oxide layer and an adjacent SOFC. The barrier layer is configured to prevent Mn or Co diffusion from the electrically conductive metal oxide layer to the adjacent SOFC.

International Classification:

H01M 4/86
H01M 4/90
H01M 8/124
H01M 4/88

Abstract:

A method for forming a solid oxide fuel cell (SOFC) includes co-firing the anode and cathode electrode layers, which involves placing an unfired anode onto a surface during the cathode print cycle. To avoid damage to the electrolyte and cathode production cycle by the green anode ink, an abrasion resistant ink is used to print the anode electrode layer.

Richard Stephenson - Sunnyvale CA, US

International Classification:

H01M 8/1226
H01M 8/1253
H01M 8/1246

Abstract:

A solid oxide fuel cell (SOFC) that includes an anode electrode, a cathode electrode and a solid oxide electrolyte having a fuel inlet riser opening and a fuel outlet riser opening. The electrolyte is located between the anode electrode and the cathode electrode. The SOFC also includes a ceramic support layer on the electrolyte. The ceramic support is layer located around the at least one of a periphery of the electrolyte or at least partially around perimeters of the fuel inlet and fuel outlet riser openings. The ceramic support layer comprises a multi-component material comprising yttria stabilized zirconia (YSZ) and alpha alumina.
