In order to create a bipolar plate for an electrochemical device, comprising at least one first bipolar plate layer and one second bipolar plate layer, between which an edge channel extending along a longitudinal direction is formed, and comprising a fluid channel running substantially in parallel to the edge channel, in which bipolar plate at least an edge channel portion of the edge channel can be flowed through by a fluid media to be supplied to the electrochemical device, for example by a fluid reaction media or by a cooling media, even though the edge channel has no direct fluidic connection to a medium channel by which the respective fluid media is supplied to the electrochemical device, it is proposed that the bipolar plate comprises at least one fluidic connection through which a fluid medium can flow from the edge channel into the adjacent fluid channel and/or from the adjacent fluid channel into the edge channel.

A fuel cell includes a cell stacked body and a manifold. The cell stacked body has elements stacked, each element having: a fuel electrode and an oxidant electrode between which the electrolyte membrane is interposed; a fuel electrode flow channel plate; and an oxidant electrode flow channel plate. The manifold is provided on a lateral surface, of the cell stacked body, along a stacking direction of the cell stacked body and feeds a reaction gas to the fuel electrode flow channel plate or the oxidant electrode flow channel plate. The manifold includes a gas flow channel part that is provided between a plurality of the cell stacked bodies arranged to line up in a first direction perpendicular to the stacking direction and that allows communication between the cell stacked bodies such that the reaction gas passes through.

A fuel cell system includes a hydrogen tank to store hydrogen, a fuel cell to receive hydrogen gas from the hydrogen tank to generate electricity, a temperature controller to adjust a temperature inside the hydrogen tank, and a control unit to control the temperature controller based on the amount of hydrogen remaining in the hydrogen tank, the control unit being configured to increase the temperature inside the hydrogen tank when the amount of the remaining hydrogen is equal to or less than a first predetermined value.
