Abstract: METHODS ARE DESCRIBED FOR FORMING ELECTRODES BY METALLIC DEPOSITION FROM A SOLUTION CONTAINING PLATINUM, PALLADIUM AND SELECTED THIRD METAL ONTO A POROUS SUBSTRATE HAVING AT LEAST A NON-NOBLE METAL COATING. THE METALLIC DEPOSITION IS ACCOMPLISHED BY SUBSTRATE IMMERSION, SUBSTRATE DIPPING, OR SUBSTRATE IMMERSION IN WHICH THE SUBSTRATE IS CONNECTED TO THE POSITIVE TERMINAL OF A POWDER SUPPLY. SUCH ELECTRODES PROVIDE HIGH PERFORMANCE ANODES FOR ELECTROCHEMICAL CELLS.

Abstract: A miniature probe contains a multifunctional electrochemical sensor which measures both the hydrogen ion activity or pH of samples and the carbon dioxide activity of samples. The miniature probe includes a carbon dioxide sensor. When the potential of one electrode in the probe is measured with respect to that of an external reference electrode, a pH sensor is provided.

Abstract: An electrochemical cell has at least one positive wet-proofed gas diffusion electrode with its major portion within the casing covered with a fuel and oxidant impervious mask, and with its remaining portion within the casing covered with at least one water soluble polymeric thickening agent swellable in the aqueous alkaline electrolyte of a fuel-electrolyte solution and an alkali metal silicate dissolved in the solution. This cell eliminates or reduces substantially the conventional problems of carbonate crust formation, electrolyte leakage, drowning of the gas diffusion electrode, and loss of fuel.

Abstract: A sensor for the partial pressure of oxygen comprises an electrode which reduces oxygen and which itself corrodes or oxidizes to produce a potential that varies with the rate of oxygen reduction. A silver halide reference electrode is encapsulated in a common electrolyte with the aforesaid electrode and the electrolyte is surrounded by an oxygen permeable, ion impermeable membrane. The electrolyte includes a halide salt and a buffer.
