PURPOSE:To secure a three-electrode solid-state electrolytic fuel cell making the evaluation of an electrode catalyzer easy, by inserting a metal wire of platinum, gold, etc., into a solid state electrolyte interposed between a fuel electrode and an oxidizer electrode as the third electrode. CONSTITUTION:A metal wire of platinum and gold or an alloy of these noble metals is inserted into a solid-state electrolyte 2 closely interposed between a fuel electrode 6 and an oxidizer electrode 7 as the third electrode 3 and in this way a three-electrode solid-state electrolytic fuel cell is made up. Each of H2 and O2 gases is poured into this cell via carbon tubes 4 and 5. According to this fuel cell, not only voltage of the cell as a whole can be measured but also the voltage between the fuel electrode 6 and the third electrode 3 as well as the voltage between the oxidizer electrode 7 and the third electrode 3 can be discriminated and measured simultaneously and thereby a wide variety of polarization can be separately evaluated. This fuel cell is widely applied to the development of an electrode catalyzer for a hydrogen-oxygen solid-state electrolytic fuel cell excellent in energy efficiency. |
