Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:

Re Claim 1. Rodriguez teaches a method for manufacturing a bipolar plate (Fig. 1, item 12) for an electrochemical cell comprising: providing a fluid impermeable carrier (item 26), applying a fluid-impermeable coating (item 30) over at least one subregion of a surface of the carrier, and forming a flow channel (item 14) on the surface of the carrier prior to applying the coating (P4), wherein the coating is applied by at least one of cold gas spraying (P3), and wherein the coating includes at least one of niobium, tantalum, tin, vanadium, silicon, or at least one of an oxide or a carbide thereof (P4).
Re Claim 2. Rodriguez teaches wherein the coating includes at least one of titanium, molybdenum, tungsten, or oxides or carbides thereof (P4).
Re Claim 3. Rodriguez teaches wherein the coating includes a titanium alloy, wherein the titanium alloy includes at least one of molybdenum, vanadium, or oxides or carbides thereof (P4).
Re Claim 4. Rodriguez teaches wherein the carrier is formed of an electrically conductive material (P5).
Re Claim 5. The method according to claim 1, wherein during the application of the coating, at least one of a composition of coating material applied to the surface is changed (P4).
Re Claim 6. Rodriguez teaches forming a plurality of flow channels on the surface of the carrier prior to applying the coating (Fig. 1, P4).
Re Claim 7. Rodriguez teaches wherein the coating is applied to elevations between the flow channels and depressions of the flow channels remain uncoated (Fig. 1, P4).
Re Claim 12. Rodriguez teaches applying particles (Fig. 2, item 32) to at least one of the surface of the carrier during applying the coating, wherein the particles include an electrically conductive material (P6)and reduce a contact resistance at the surface of the coated carrier.
