Cost, durability, and reliability are the major issues hindering the commercialization of polymer electrolyte membrane fuel cells. Electrolyte membranes present in the fuel cell fails under chemical, thermal, and mechanical influences, which, in turn, results in the overall fuel cell failure.

The viscoelastic fluids showed a trade-off between shear thinning and elasticity. Thtee fluids were Boger-like in that they exhibited nearly constant viscosity in simple shear but had significant elasticity. Two liquids obeyed the Carreau model but showed significant elasticity. AJl five liquids exhibited varying degrees of the Weissenberg effect. Slot Die Coating - Kerone In the Slot Die process, the coating is pressed out by gravity or under weight through a slot and onto the substrate. In the event that the coating is 100% solids, the process is termed "Extrusion" and for this situation, the line velocity is regularly much speedier than the rate of the extrusion.
