1. A flow structure for use in an electrochemical cell, comprising:

  • a compacted porous metallic substrate having a void volume greater than about 55% and yield strength greater than about 12,000 psi, wherein the compacted porous metallic substrate is formed by;

    selecting a porous metallic substrate with a void volume between about 75% and about 98%; and

    compacting uniformly the porous metallic substrate causing plastic deformation and thereby forming the compacted porous metallic substrate and increasing the yield strength to greater than about 12,000 psi;

    at least one micro-porous material layer laminated on one side of the compacted porous metallic substrate, wherein an average pore size of the at least one micro-porous material layer is smaller than an average pore size of the compacted porous metallic substrate.
