1. method that is used to make the flow field, said method comprises step:

  • Substrate is provided;

    The a plurality of radiation sources that are configured to produce a plurality of radiation beams are provided;

    Radiation-sensitive materials is arranged on the said substrate;

    The mask that will form images is placed between said a plurality of radiation source and the said radiation-sensitive materials;

    Said imaging mask has the permeable hole of a plurality of roughly radiation;

    The permeable hole of said roughly radiation comprises at least one in first and the second portion;

    The said first of said hole is configured to be shaped from the said radiation beam of said radiation source in said radiation-sensitive materials, forming a plurality of truss members, and the said second portion of said hole is configured to be shaped said radiation beam from said radiation source in said radiation-sensitive materials, to form a plurality of wall elements;

    AndIn the said first through the permeable hole of said radiation in the said imaging mask and the said second portion of the permeable hole of said radiation at least one;

    Make said radiation-sensitive materials be exposed to said a plurality of radiation beam;

    In said radiation-sensitive materials, to form at least one in said a plurality of truss members and the said a plurality of wall elements;

    Said truss members forms a plurality of truss that are configured to support adjacent diffusion media layers, and said wall elements limits along the fluid path of the length of said substrate.
