ABSTRACT:
A simple method of producing an oxygen concentration cell provided with durable electrodes having a high activity and a low internal resistance is disclosed. The method comprises applying a solution of a compound of platinum group metal to an oxygen ion conductive solid electrolyte, converting the compound into an insoluble or hardly soluble compound by a chemical reaction, and thermally decomposing the insoluble or hardly soluble compound into the platinum group metal to be used as the electrodes of the cell.
