PROBLEM TO BE SOLVED: To provide an electrochemical reactor cell which is hard to cause a trouble, such as a disconnection, short circuit, or a crack, in a current collecting part, and enables the achievement of a high reaction efficiency over a long period of time.SOLUTION: The present invention provides a tube type electrochemical reactor cell which comprises: a tube type anode 12; a solid electrolyte 14 laminated on the surface of the tube type anode; and a cathode 16 laminated thereon in turn. The solid electrolyte 14 and the cathode 16 are not provided on one end portion 13A of the cell in a longitudinal direction thereof and therefore, the anode 12 is exposed. The tube type electrochemical reactor cell further comprises a current collecting part 18 provided on the exposed portion of the anode 12. The current collecting part 18 includes a perovskite oxide expressed by the following general formula: (LaSr)(MFe)O(where M represents Ti and/or Al; 0.1<x≤0.7; 0<y≤0.9; and δ is a value determined to meet a charge neutral condition). |
