Sealing arrangement for thin large area parts

摘要

The arrangement has individual sealing elements (10) inserted into apertures to form an integral unit with the associated bipolar plates. Free vol. or spaces (13) are formed between the side walls (11) of the sealing elements and the adjacent walls of the apertures to accommodate the elastic sealing material displaced by compression, whereby prior to compression the sealing elements only partly fill the apertures or gaps and the height of the sealing elements is greater than the depth of the apertures or gaps
