PURPOSE:To simplify the construction, by installing a pair of electrodes of different catalystic functions on a member of a solid electrolytic board having oxygen ion conductive property. CONSTITUTION:On the surfaces of oblong solid electrolytic board 1, which is approximately 0.5mm thick composed of solid solutions of zirconium and ytterium, etc., a cathode 2, approximately 20mum thick, of electrode material of such strong catalystic property as Pt, etc., and an anode 3 approximately 20mum thick, of electrode material of such weak catalystic property as Au, etc. are installed respectively. Electromotive force generated between the electrodes 2, 3 can be derived out from output terminals 2a, 3a led out from the central area of the shorter side. Thus, simplification of the construction becomes available. |
