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.

Abstract: Solid oxide fuel cells and methods for fabricating solid oxide fuel cells include an electrolyte reinforcement (ERI) layer. An ink composition including a ceramic material and a sintering aid, such as a metal or metal oxide material, is applied to select portions of a solid oxide electrolyte and sintered to form an ERI layer. The ERI layer may improve the strength and durability of the electrolyte and may facilitate bonding to a high-temperature seal.

Abstract: Embodiments of the present invention are directed to ternary and/or quaternary catalyst alloys for a direct methanol fuel cell (DMFC). The catalyst has the composition (Pt1-xRux)yM?zM?1-y-z, where M? is selected from the group consisting of W, Mo, Nb, and Ta; M? is selected from the group consisting of V, Co, Ni, Mn, and Cu; x ranges from about 0 to about 1; y ranges from about 0.01 to about 0.99; and y+z is about equal to 1. The catalyst may be deposited onto a porous carrier, and the deposition method may include ion-beam sputtering. The onset voltages of the present compositions are lower than that of conventional Pt—Ru binary systems by approximately 0.355 volts, and thus provide enhanced catalytic activity.
