1. A collector plate comprising a conductive body comprising a cathode collecting face and an anode collecting face, and at least one channel on the cathode collecting face or the anode collecting face, wherein the cathode collecting face and the anode collecting face are configured to form a seal so that the at least one channel is closed; wherein at least a part of a wall of the at least one channel comprises a bulk-solidifying amorphous alloy, wherein the bulk-solidifying amorphous alloy has an elastic strain limit of about 1.8% or more, wherein the bulk solidifying amorphous alloy retains an amorphous atomic structure in a thickness of 1 mm or more when cooled from a molten state at a cooling rate of 500 K/sec or less. 2. The collector plate of claim 1, wherein the bulk solidifying amorphous alloy has a high fracture toughness of at least 20 ksi-in0.5. 3. The collector plate of claim 1, wherein the bulk solidifying amorphous alloy has a ΔT of 60° C. or greater. 4. The collector plate of claim 1, wherein the bulk solidifying amorphous alloy has a glass transition temperature Tg of greater than 300° C. 5. The collector plate of claim 1, wherein the bulk solidifying amorphous alloy has a strength of 200 ksi or more. 6. The collector plate of claim 1, wherein the bulk solidifying amorphous alloy has a hardness of 400 Vickers or more. 7. The collector plate of claim 1, wherein the bulk solidifying amorphous alloy has an electrical conductivity of about 5000 S/cm or more. 8. The collector plate of claim 1, wherein the bulk solidifying amorphous alloy is described by the molecular formula: (Zr, Ti)a(Ni, Cu, Fe)b(Be, Al, Si, B)c, wherein “a” is in the range of from 30 to 75, “b” is in the range of from 5 to 60, and “c” in the range of from 0 to 50 in atomic percentages or the bulk solidifying amorphous alloy is described by the following molecular formula: (Zr, Ti)a(Ni, Cu)b(Be)c, wherein “a” is in the range of from 40 to 75, “b” is in the range of from 5 to 50, and “c” in the range of from 5 to 50 in atomic percentages. 9. The collector plate of claim 1, wherein the bulk-solidifying amorphous alloy comprises a composition being represented by the following general formula: Nia (Zr1-xTix)b Sic where a, b and c are atomic percentages of nickel, zirconium plus titanium and silicon, respectively, and x is an atomic fraction of titanium to zirconium, wherein 45 atomic %≦a≦63 atomic %, 32 atomic %≦b≦48 atomic %, 1 atomic %≦c≦11 atomic %, and 0.4≦x≦0.6. 10. A collector plate of claim 1, wherein the wall has a thickness of 1 mm or less. 11. The collector plate of claim 10, wherein the conductive body comprises a heat exchange channel between the cathode collecting face and the anode collecting face. 12. A device comprising the collector plate of claim 1, wherein the device is configured to generate electricity from a fuel, wherein the device comprises a catalyst configured to oxidize the fuel, an opposing electrode, an electrolyte/ion exchange layer and reactants. 13. The device of claim 12, further comprising an oxidizing agent. 14. The device of claim 12, wherein the fuel is located in the at least one channel in the anode collecting face. 15. The device of claim 12, wherein the oxidizing agent is located in the at least one channel in the cathode collecting face. 16. The device of claim 13, wherein the oxidizing agent is a gas comprising oxygen. 17. The device of claim 12, wherein the fuel comprises hydrogen gas.
