Verfahren zur Herstellung einer Brennstoffzelle auf einem porösen Untergrund

摘要

The method involves forming an electrode-membrane-electrode assembly constituted of an anode, a solid proton conducting membrane and a cathode on a porous support (2), where the support has pores (2a) delimited by walls (2b) of the support. The membrane is formed by depositing and drying a liquid electrolyte. A film (10), which is constituted by a material i.e. polymer, presenting a contact angle greater than 90 degree with a drop of the liquid electrolyte, is formed on a part of the walls, where the film has a thickness allowing the passage of a reactive fluid in the pores.
