Abstract

An electrode is attached to a solid electrolyte material by: (1) mixing a metallic nickel component and 1 wt% to 10 wt% of yttria stabilized zirconia having particle diameters up to 3 micrometers with an organic binder solution to form a slurry, (2) applying the slurry to a solid zirconia electrolyte material, (3) heating the slurry to drive off the organic binder and form a porous layer of metallic nickel substantially surrounded and separated by the zirconia particles, and (4) electro-chemical vapor depositing a skeletal structure between and around the metallic nickel and the zirconia particles where the metallic nickel components do not substantially sinter to each other, yet the layer remains porous. 4 figs.

Fuel cell anode electrode, method of making the fuel cell anode electrode, and fuel cell containing the fuel cell anode electrode

Patent Perry, J.

A fuel cell anode electrode for use in fuel cells utilizing fuel electrolyte mixtures of methanol in potassium hydroxide electrolyte and ethylene glycol in potassium hydroxide electrolyte is made by pressing a paste mix of noble metal powder, graphite, and teflon onto a screen current collector, drying the electrode so formed, cathodically charging the electrode at a current density of about 2 1/2 to 10 mA/sq. cm for about 2 to about 6 minutes to deposit lead through electrolysis using a saturated solution of lead chloride, anodically charging the electrode for about 2 to about 12 minutes to oxidize themore »« less

Method of making composition suitable for use as inert electrode having good electrical conductivity and mechanical properties

Patent Ray, S.P.; Rapp, R.A.

An improved inert electrode composition is suitable for use as an inert electrode in the production of metals such as aluminum by the electrolytic reduction of metal oxide or metal salt dissolved in a molten salt bath. The composition comprises one or more metals or metal alloys and metal compounds which may include oxides of the metals comprising the alloy. The alloy and metal compounds are interwoven in a network which provides improved electrical conductivity and mechanical strength while preserving the level of chemical inertness necessary for such an electrode to function satisfactorily. 8 figs.
