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.

Fuel cell stack assembly - datum design for fuel cell stacking and collision protection

Номер: US20160072145A1
Автор: David A. Martinchek, Martin Heinzmann, Robert C. Thompson
Принадлежит: GM GLOBAL TECHNOLOGY OPERATIONS LLC

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 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. In one form, the use of welding, bonding or related attachment of the datum to the plate promotes enhanced metallic support without the need for increasing the plate footprint and without having to overmold the datum directly onto the plate.

Seal material with latent adhesive properties and a method of sealing fuel cell components with same

Номер: US20170226392A1
Автор: Andrew P. Nowak, Anita Luong, Yeh-Hung Lai
Принадлежит: GM GLOBAL TECHNOLOGY OPERATIONS LLC

A composition with latent adhesion, fuel cell stack with a bipolar plate assembly with latent adhesion and a method of assembling a fuel cell stack with a seal that has latent adhesion such that reactant or coolant leakage through the seal is reduced. Bipolar plates within the stack include reactant channels and coolant channels that are fluidly coupled to inlet and outlet flowpaths, all of which are formed within a coolant-engaging or reactant-engaging surface of the plate. One or more thin or low aspect-ratio seals are formed on a metal bead that is integrally-formed on a surface of the plate and is used to help reduce leakage by maintaining fluid isolation of the reactants and coolant as they flow through their respective channels and flowpaths that are defined between adjacently-placed plates. By proper formulation of the precursor materials that make up the seal, the activation of the adhesive bond formed between the seal and an adjacent surface within the fuel cell can be delayed to allow ample time to aligned and compressively join the cell assemblies in a stack housing. This in turn improves the ability of the seal and its adjacent surface to avoid seal damage and concomitant reactant or coolant leakage.
