Fuel cell stack has at least one bipolar plate forming flow field, at least one flow control element arranged inside supply channel and associated with at least one flow field and/or flow channel

摘要

The fuel cell stack (1) has at least one bipolar plate (1.1) forming a flow field with at least one associated supply channel (2) for a liquid and/or a gas. The supply channel has flow connections to several flow channels (1.2) in the flow fields. At least one flow control element (2.1) is arranged inside the supply channel and is associated with at least one flow field and/or the flow channel.
