Abstract

Zwischenraumspalte in den inaktiven Zufuhrbereichen eines Brennstoffzellenstapels werden durch nicht verbundene, nicht ineinandergesetzte Bipolarplatten gesteuert, um eine Reaktandenströmungsgleichförmigkeit und Druck in Brennstoffzellen und Brennstoffzellenstapeln vorzusehen, die ineinandergesetzte Bipolarplatten in den aktiven Zufuhrbereichen und nicht ineinandergesetzte Bipolarplatten in den inaktiven Zufuhrbereichen verwenden.
