Abstract

A contact element for contacting a bipolar plate of a fuel cell stack includes a contact body extending along a longitudinal axis. The contact body has a channel extending along the longitudinal axis and delimited by a pair of channel walls disposed opposite one another in a direction transverse to the longitudinal axis. The channel is adapted to receive a portion of the bipolar plate. The contact body has a contact spring on a first channel wall of the pair of channel walls. The contact spring protrudes into the channel and has a cutting edge directed toward a second channel wall of the pair of channels walls and adapted to contact the bipolar plate.
