Verfahren zur Herstellung von gasdurchlaessigen,hydrophoben Folien fuer elektrochemische Zellen,insbesondere Brennstoffzellen

摘要

Gas permeable hydrophobic foils useful for electrochemical cells prepared by covering a temperature resistant hot plate or mold with a temperature resistant release layer, spraying a suspension or solution of a fluorine containing polymer onto said release layer and sintering the polymer.
