Fuel cell electrode
Abstract
Abstract A fuel cell electrode is composed of catalytic and gas adsorbing materials which consist of a chromium-tungsten oxide as a support, a metal dispersed on the support, the metal selected from the class consisting of noble metals and alloys of noble metals, a current collector, and a binder bonding the materials together and to the current collector in electronically conductive relationship. Further, the catalytic and gas adsorbing materials comprise a chromium-tungsten oxide as a support, a support of carbon with boron dissolved therein, a mixture of carbon with boron dissolved therein and boron carbide, or carbon, and a metal dispersed on both of the supports, the metal selected from the class consisting of noble metals and alloys of noble metals. An adhesive binder is employed which is not chemically attacked by the electrolyte or the reactant fluid of the cell in which the electrode is used. Such an electrode is particularly useful in a fuel cell employing a fuel containing carbon monoxide, such as reformer gas, an acid electrolyte, and under various operating conditions.
