Stack of electro-chemical cells is each separated from adjacent cell by bipolar partition panel with apertures associated with crimped elastic closures

摘要

An electro-chemical gas compressor has a stack (1) of electrochemical cells (2) bipolar plate partitions (3. 3'). The plates have apertures for the admission and discharge of media to and from the cells. The stack shape is retained by compression fixtures. The apertures (4, 5a, 5b, 10) especially have elastic crimped closures which open or shut off a zone within the cell. On one side each electrochemical cell is separated from the bipolar partition by a gas diffusion panel (9) fabricated from a conductor e.g. made of metal fibers. The crimped zones have an elastic coating of an agent applied by screen printing, tampon print, spray or the cured in-place gasket process.
