Abstract
An electrochemical cell capable of operating in pressure differentials exceeding about 2,000 psi, using a porous electrode. The porous electrode comprises a catalyst adsorbed on or in a porous support that is disposed in intimate contact and fluid communication with the electrolyte membrane.
Claims13
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.
A method for making a porous electrode, comprising:
- coating an electrically conductive material with a catalyst;
- forming a layer of said coated material;
