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: AN ELECTROCHEMICAL BATTERY HAS A PLURALITY OF INDIVIDUAL, FLUID-TIGHT FUEL-ELECTROLYTE CHAMBERS IN EACH OF WHICH AN ANODE AND A GAS DIFFUSION CATHODE MOUNTED THEREIN ARE CONNECTED ELECTRICALLY TO THE RESPECTIVE GAS DIFFUSION CATHODE AND ANODE OF ADJACENT CELLS. THE ELECTROLYTE CONTAINING DISSOLVED FUEL IN EACH CELL IS SEPARATED FROM ADJACENT CELLS THEREBY ELIMINATING LOAD PATHS ACROSS CELLS. SUCH A BATTERY PROVIDES A HIGH VOLTAGE OUTPUT FROM A CONPACT DEVICE.
