Abstract

A cassette less SOFC assembly and a method for creating such an assembly. The SOFC stack is characterized by an electrically isolated stack current path which allows welded interconnection between frame portions of the stack. In one embodiment electrically isolating a current path comprises the step of sealing a interconnect plate to a interconnect plate frame with an insulating seal. This enables the current path portion to be isolated from the structural frame an enables the cell frame to be welded together.

Cassettes for solid-oxide fuel cell stacks and methods of making the same

Patent Weil, K. Scott; Meinhardt, Kerry D; Sprenkle, Vincent L

Solid-oxide fuel cell (SOFC) stack assembly designs are consistently investigated to develop an assembly that provides optimal performance, and durability, within desired cost parameters. A new design includes a repeat unit having a SOFC cassette and being characterized by a three-component construct. The three components include an oxidation-resistant, metal window frame hermetically joined to an electrolyte layer of a multi-layer, anode-supported ceramic cell and a pre-cassette including a separator plate having a plurality of vias that provide electrical contact between an anode-side collector within the pre-cassette and a cathode-side current collector of an adjacent cell. The third component is amore » « less

Method of nucleic acid cassette assembly

Patent Venter, J. Craig; Smith, Hamilton O.; Hutchison, III, Clyde A.; ...

Methods are provided for constructing a synthetic genome, comprising generating and assembling nucleic acid cassettes comprising portions of the genome, wherein at least one of the nucleic acid cassettes is constructed from nucleic acid components that have been chemically synthesized, or from copies of the chemically synthesized nucleic acid components. In one embodiment, the entire synthetic genome is constructed from nucleic acid components that have been chemically synthesized, or from copies of the chemically synthesized nucleic acid components. Rational methods may be used to design the synthetic genome (e.g., to establish a minimal genome and/or to optimize the function ofmore » « less

Fuel cell stack including non-fuel cell cassette

Patent Haltiner, Jr., Karl J.; Maczynski, Stefan M.; Hendler, Peter E.

A fuel cell stack is disclosed including a non-fuel cell cassette having temperature sensing elements disposed therein. The temperature sensing elements are disposed in one or more void spaces in the non-fuel cell cassette, which void spaces are connected to openings in the side of the non-fuel cell cassette for lead wires to communicate information from the temperature sensing elements to components outside of the fuel cell stack.
