Abstract
A bipolar plate, for an electrochemical system, having a rectangular basic shape is provided. The bipolar plate includes two operating media ports and one coolant port arranged next to one another on each of the plate narrow sides. The coolant port is located between the operating media ports and has a port longitudinal side aligned parallel to the plate narrow side. Each operating media port has a port longitudinal side aligned parallel to a plate longitudinal side. A rectangular active field is located between the three ports on one plate narrow side and the three ports on the opposite plate narrow side. The active field has two active-field longitudinal sides. The active field includes linear channels for directing the flow of the operating media and the coolant parallel to the active-field longitudinal sides.

A bipolar plate for an electrochemical system, having a rectangular basic shape, the bipolar plate comprising:
- three ports positioned on a plate narrow side, the three ports include two operating media-means ports and one coolant port arranged next to one another, wherein the coolant port is positioned between the operating media ports and has a port longitudinal side oriented parallel to the plate narrow side, wherein each operating media port has a port longitudinal side oriented parallel to a plate longitudinal side,
- a rectangular active field arranged between the three ports on a plate narrow side and the three ports on the opposite plate narrow side, wherein the rectangular active field includes:
- two active-field longitudinal sides, each active-field longitudinal side arranged parallel to the plate longitudinal sides, and
- linear channels for directing flow of the operating media and directing flow of the coolant parallel to the active-field longitudinal sides,
- wherein a product of a length of the port longitudinal side of the coolant port and a length of the port longitudinal side of one of the two operating media ports adjacent to the coolant port is at least six times a product of a length of a port narrow side of the coolant port and a length of a port narrow side of the operating media port.
