Abstract
1,250,259. Electro-chemical cells. WESTINGHOUSE ELECTRIC CORP. Oct. 15, 1969 [Nov. 5, 1968], No. 50664/69. Heading GIN. An electro-chemical cell 1 comprises first and second electrodes 12, 14 disposed on opposed surfaces of a tubular, solid electrolyte member 10, a voltage source 24 and an ammeter 28. In use, a reference gas of known oxygen concentration is flowed through the tube while a sample gas is flowed along its external surface, a predetermined voltage being applied from the source so as to establish diffusion limited current operation when, it is stated, the current flowing between the electrodes is a function of the amount of oxygen present in the sample gas. To increase the ionic conductivity of the electrolyte an electrical heater is disposed about it and set to give an operating temperature in the range 600‹ C. to 1000‹C. The electrolyte is a solid solution of zirconium oxide and one or more of the oxides of borium, calcium lanthanum, scondium, strontium or yttrium. The electrodes are platinum and made porous to oxygen. In an alternative embodiment, Fig. 4 (not shown) separate gas chambers for the reference (52) and the sample (50) are joined by a solid zirconium oxide electrolyte (32) bearing, on opposite faces, platinum electrodes (34, 36), the former in the sample gas chamber and the latter in the reference gas chamber. A further modification dispenses with a separate reference gas, sample gas flowing between chambers (50) and (52) by way of passages (60).
