Fabrication of aluminum bipolar plates with Archimedes' screw-shaped channels: a rubber pad forming process assessment

Abstract Bipolar plates are one of the most important components polymer membrane fuel cells. In this manuscript, rubber pad forming aluminum bipolar with Archimedes' screw-shaped channels and draft angle 90 $$^\circ$$ ∘ has been investigated. Hence, all possible combinations process parameters were determined corresponding experimentations performed in order to investigate effects hardness, punch speed hydraulic press force. regard, three pads including polyurethane, silicone natural used. Channel depth thinning percentage corner channel measured effect each parameter is analyzed. Based on results, maximum was achieved using a hardness 60 Shore A. Using very high low number, both, reduces channel. Furthermore, as increases, increases percentage, well.
