DEVICE FOR ELECTROCHEMICAL ANALYSIS OF TUBULAR FUEL CELLS, PREPARATION METHOD FOR ELECTROCHEMICAL ANALYSIS AND METHOD OF INVESTIGATION Russian patent published in 2020 - IPC G01N27/26 

FIELD: chemistry.

SUBSTANCE: invention can be used for investigation of electrochemical devices based on high-temperature tubular ceramic fuel cells, including microtubular solid oxide fuel cells (SOFC). Essence of the invention consists in that the device for electrochemical examination of high-temperature tubular fuel cells includes a protective reactor with flanges and a coaxially carrying tubular base with a sector cut-out and two gas supply tubes, wherein in both flanges there are holes for current-collecting wires, gas supply tubes and, respectively, for supply and discharge of oxygen-containing agent, and at least one flange is equipped with threaded retainer.

EFFECT: technical result is providing the possibility of creating a reliable supporting structure, in which possible mechanical stresses are minimized, the possibility of varying the geometric parameters of the analysed samples within a wide range is realized with preservation of their chemical stability under high temperatures.
