The following disclosure relates to junctions for combining a flow at an outlet manifold. More specifically, the following disclosure relates to junctions configured to reduce outlet manifold pressure enabling the use of smaller outlet manifolds for electrochemical cells and cell stacks.

Geometric shapes for reduced manifold pressure drop

A flow field plate comprises a first flow field; an opposing second flow field; and at least one flow channel formed in the first flow field, the at least one flow channel comprising: a first side and an opposing second side separated by an open-faced top and a bottom; and a first side channel formed in a portion of the open-faced top and in a portion of the first side along a continuous length of the at least one flow channel, the first side channel comprising a first side wall and a first bottom wall; wherein the first side wall of the first side channel and the first bottom wall of the first side channel form an obtuse angle in cross-section; and a depth of the bottom of the at least one flow channel is greater than a depth of the bottom wall of the first side channel.

Flow field plate for electrochemical fuel cell

An electrochemical fuel cell stack having staggered fuel and oxidant plenums is disclosed. This construction allows for reduced cell pitch without reducing plenum thickness and hence fluid flow.
