1. A junction apparatus comprising:
a first outlet having a first diameter configured to supply a first flow from a first plurality of electrochemical cells or a first electrochemical stack to an outlet manifold having a diameter; and
one or more secondary outlets having second diameters configured to supply one or more secondary flows from one or more second plurality of electrochemical cells or one or more second electrochemical stacks to the outlet manifold, the one or more secondary outlets having inclination angles relative to the outlet manifold configured to reduce a pressure in the outlet manifold by creating a uniform circular flow in the outlet manifold,
wherein a length of the first diameter of the first outlet and a length of the diameter of the outlet manifold are within 10% of each other, and
wherein lengths of the second diameters of the one or more secondary outlets and the length of the diameter of the outlet manifold are within 10% of each other.
