Abstract:
1. A separator for electrochemical systems, comprising: a first conductive plate having a face and defining a plane; and a second conductive plate having a face; wherein each plate includes a series of projections extending outwardly therefrom; wherein each of the projections have a corresponding cavity defined on the opposite side thereof in the face of the respective plate; wherein when the faces of the first and second plates are brought into an overlapping relationship facing one another, at least a subset of the cavities of the first plate engage a subset of the cavities of the second plate to provide at least one flow path between the first plate and the second plate; wherein the cavities of the first plate are dissimilar in shape from the cavities of the second plate; wherein the cavities on the first plate are discrete and spaced from one another in a distributed manner over the face of the first plate defining a region having a periphery, such that the cavities on the face of the first plate form no continuous channel entirely within the plane of the first plate and linking one edge of the periphery of the region of the face of the first plate with another edge of the periphery of the region of the face of the first plate; and wherein the cavities on the second plate form at least one connecting passage between discrete and spaced apart cavities on the first plate.
