Compression bar

Two compression bars are shown across the top of each module in Figure 12. These bars are used to maintain compression on all of the stacks during operation in order to minimise electrical contact resistance between the cells, flow fields and interconnects. The bars are held in compression via spring-loaded tie-downs located outside of the hot zone under the base plate.

Figure 7.13 Schematic view of a simple JUm trough A and B are movable barriers, is the compression bar, are barrier ribbons, is the torsion wire, is thejloat.

The barrier is left a few centimeters away from the end of the trough. This operation is repeated with another barrier B from the other end of the trough. A third barrier C, also called a compression bar is then placed in position. It can be moved horizontally to decrease or increase the film covered area (Figure 7.14). The surface of the solution is separated into two parts by means of a teflon-coated aluminium or mica float, F. A torsion wire W, is connected to the float. The float also has two non-wettable ribbons T, and T connected to the sides of the trough. 

Viscoelastic properties are often determined with steady state oscillation or vibratory tests using small tensile (compressive) bars, thin cylinders or flat strips in torsion, beams in bending, etc. The approach is usually referred to as dynamic mechanical analysis (DMA) testing or sometimes dynamic mechanical thermal analysis (DMTA). The latter term is more appropriate as properties are often determined and expressed in terms of temperature...
