Abstract: A fuel cell stack and a method of assembling a fuel cell stack includes compressing fuel cells along their stacking axis. A compression retention device made up of an enclosure may be used with one or more optional insertable shims to correct for any stack height variations. Significantly, the enclosure is formed to allow the stack to be loaded in compression by a press such that the cells that make up the stack are placed into and maintained in a substantially compressed state while the compression force is not imparted to the enclosure. By resolving any stack height variances while the cells of the stack are maintained in their substantially compressed state, assembly operations are simplified in that repeated compression and decompression of the stack is avoided while trying to ensure that the stack and enclosure are joined into their final assembly form.

Abstract: A passive tortuous path drain for a directing fluid flow from an enclosure includes a drain body having a front face and a back face. The front face defines a curved trenched channel having a first curved channel end and a second curved channel end. The front face also defines a second trenched channel. The drain body defines at least one egress opening in fluid communication with the second trenched channel. The first curved channel end and a second curved channel end are in fluid communication with the second trenched channel. Characteristically, the drain is adapted to be positioned adjacent to a drain opening in an enclosure such that liquid flows from the drain opening to the curved trenched channel and then to the second trenched channel exiting through the egress opening.

Abstract: A fuel cell stack assembly is provided which includes a first bipolar plate, a second bipolar plate, a sub-gasket, and a gas diffusion layer. The second bipolar plate may define a bypass channel with the first bipolar plate. The bypass channel includes at least one embossment formed therein. The gas diffusion layer may be disposed between the first bipolar plate and the second bipolar plate while the sub-gasket is sandwiched between metal bead seals formed in each of the first bipolar plate and the second bi-polar plate.

Abstract: A system and method for aligning and reducing the relative movement between adjacent fuel cells within a fuel cell stack. The inter-cell cooperation between fuel cells along a stacking dimension is enhanced by one or more datum placed along the edge of a bipolar plate that makes up a part of a cell-containing assembly. The datum is shaped along a thickness that substantially coincides with the cell stacking dimension to avoid shifting between adjacently-stacked cells that may otherwise arise out of the occurrence of a significant acceleration along the dimension that defines the major surfaces of the plates, cells and their respective assemblies. By having the datum be integrally formed with numerous stacked cells, the need to affix individual tabs each plate is avoided.

The inter-cell cooperation between fuel cells along a stacking dimension is enhanced by one or more datum placed along the edge of a bipolar plate that makes up a part of a cell-containing assembly. The datum is shaped along a thickness dimension that substantially coincides with the cell stacking dimension to promote a nested fit with a comparable datum on an adjacently-stacked bipolar plate. This nesting facilitates an interference fit that enhances the resistance to sliding movement between respective cells that may otherwise arise out of the occurrence of a significant acceleration along the dimension that defines the major surfaces of the plates, cells and their respective assemblies.

Abstract: A computer-based method for generating multi-generational relationships within a relational model. The method includes applying, with a processing device, a filter to parent node data and child node data in the relational model, the relational model stored in a computer memory, adding filtered data to a database within a computer memory via instructions executed by the processing device, the filtered data including relational model data that passed through the filter, and applying, through instructions executed by the processing device, a parent node selection process to every child node in the filtered data that is associated with a parent node record not conforming to the filter.

Abstract: A system is provided for improved elections which may separate the identity of the voter from the content of the vote she casts. The system may be implemented using electronic or other communication methods. Separate entities may be used to implement the system, with one entity acting as a member services system, and another entity acting as an election services system. The member services system may control voter information for all members of a group eligible to vote in a specific election. The election services system may control the voting process, including receiving votes from members, without having access to the voter information controlled by the member services system. The two entities might be configured so that no single person or organization may connect the voter information to a particular vote. This separation of voter information from information in the members' votes may comply with various government regulations relating to elections.
