Claims
- 1. A method for making a porous electrode, comprising:
sintering a layer of electrically conductive material to form a sintered porous support having a porosity of greater than about 10%; and infiltrating said sintered porous support with a catalyst.
- 2. A method for making a porous electrode as in claim 1, wherein the porous electrode has a mean pore size of about 2 to about 13 microns.
- 3. A method for making a porous electrode as in claim 1, wherein said material is nickel, cobalt, titanium, zirconium, hafnium, niobium, tungsten, carbon, iron, or mixtures or alloys thereof.
- 4. A method for making a porous electrode as in claim 1, wherein said sintered porous support has a porosity greater than about 40%.
- 5. A method for making a porous electrode, comprising:
coating an electrically conductive material with a catalyst; forming a layer of said coated material; and sintering said layer to form the porous electrode, wherein said porous electrode has a porosity greater than about 20%.
- 6. A method for making a porous electrode as in claim 5, wherein said porous electrode has a porosity greater than about 40%.
- 7. A method for making a porous electrode as in claim 6, wherein said porous electrode has a mean pore size of about 2 to about 13 microns.
- 8. A method for making a porous electrode as in claim 5, wherein said material is nickel, cobalt, titanium, zirconium, hafnium, niobium, tungsten, carbon, iron, or mixtures or alloys thereof.
- 9. A method for making a porous electrode, comprising
coating an electrically conductive, porous support with a solution of catalyst precursor; and converting said catalyst precursor to a catalyst.
- 10. A method for making a porous electrode as in claim 9, wherein the electrode has a porosity greater than about 20% by volume.
- 11. A method for making a porous electrode as in claim 9, wherein the porous electrode has a mean pore size of about 2 to about 13 microns.
- 12. A method for making a porous electrode as in claim 9, wherein said material is nickel, cobalt, titanium, zirconium, hafnium, niobium, tungsten, carbon, iron, or mixtures or alloys thereof.
- 13. A method for making a porous electrode as in claim 9, wherein said sintered porous support has a porosity greater than about 40% by volume.
