A support member (20) is useful for supporting membranes such as solid polymer electrolyte ion exchange membranes such as those used in electrochemical cell applications. The support member (20) has a first lattice pattern (24) on a first side (28) of a single piece (22) of material. A second lattice pattern (30) on a second side (32) of the single piece (22) of material cooperates with the first lattice pattern (24) to establish a plurality of flow passages across the material. Each lattice pattern (24, 30) has a corresponding plurality of recesses (26, 34) that extend partway through the material and overlapping portions of the recesses (26, 34) define the flow passages. In a disclosed example, the monolithic support member lattice patterns (24, 30) are established using chemical etching. |
