Title (EN) FLOW PLATE
(FR) PLAQUE DE DISTRIBUTION
(DE) STRÖMUNGSPLATTE
Abstract:
(EN) The invention relates to a flow plate (lOa-b), in particular a bipolar plate, for a fuel cell (12a-b), in particular for a PEM fuel cell, having at least one porous flow element (14a-b). According to the invention, the flow element (14a-b) has an anisotropic flow resistance.
(FR) L'invention concerne une plaque de distribution (10a-b), en particulier une plaque bipolaire, pour une pile à combustible (12a-b), en particulier pour une pile à combustible à membrane échangeuse de protons, qui comprend au moins un élément de distribution poreux (14a-b). Selon l'invention, cet élément de distribution (14a-b) présente une résistance à l'écoulement anisotrope.
(DE) Die Erfindung geht aus von einer Strömungsplatte (lOa-b), insbesondere von einer Bipolarplatte, für eine Brennstoffzelle (12a-b), insbesondere für eine PEM- Brennstoffzelle, mit zumindest einem porösen Strömungselement (14a-b). Es wird vorgeschlagen, dass das Strömungselement (14a-b) einen anisotropen Strömungswiderstand aufweist.
