Abstract
(DE)
Die Erfindung bezieht sich auf eine Verteilerstruktur (12, 20), insbesondere eine Bipolarplattefür einen Stapelaufbau (10) einer Brennstoffzelle oder eines Elektrolyseurs. Die Verteilerstruktur (12, 20) umfasst eine Kanalstruktur (48), die mit mindestens einer Polymermembran (16) zusammenwirkt. Die Verteilerstruktur (12, 20) ist als Kunststoffteil (40) ausgeführt, das elektrisch leitende Eigenschaften aufweist.
(EN)
The invention relates to a distributor structure (12, 20), particularly a bipolar plate for a stack structure (10) of a fuel cell or of an electrolyser. The distributor structure (12, 20) comprises a channel structure (48) that interacts with at least one polymer membrane (16). The distributor structure (12, 20) is designed as a plastic part (40) that has electrically conductive properties.
(FR)
L’invention concerne une structure de distribution (12, 20), en particulier une plaque bipolaire, pour un empilage (10) d’une pile à combustible ou d’un électrolyseur. La structure de distribution (12, 20) comprend une structure de canal (48), qui interagit avec au moins une membrane polymère (16). La structure de distribution (12, 20) est réalisée sous la forme d’une pièce en matière plastique (40), qui présente des propriétés de conduction électrique.
