ABSTRACT OF THE DISCLOSURE An oxygen conductive solid electrolyte plate has first and second opposite surfaces. First and second electrodes fixedly extend on the first and second surfaces of the electrolyte plate respectively. A spacing frame hermetically secured to the first surface of the electrolyte plate surrounds the first electrode. The spacing frame has an opening. A sealing plate hermetically secured to the spacing frame defines a chamber in conjunction with the electrolyte plate and the spacing frame. The chamber accommodates the first electrode and opens into an environment only via a window defined by the opening in the spacing frame. The window allows oxygen molecules to flow from the environment into the chamber by diffusion.
