The invention relates to high-temperature electrochemical devices with a solid oxide electrolyte, and can be used for manufacturing a high-temperature fuel cell and an electrochemical current generator based on same. A tubular high-temperature fuel cell including a bearing ceramic cathode, a sectional electrolyte, an interface layer positioned between the electrolyte and the ceramic cathode, anodes with anode current collectors, and cathode current collectors. A protective film is positioned on the outer surface of the ceramic cathode in gaps between neighboring sections of electrolyte, onto which protective film a metal film is applied. The cathode current collectors are connected to the metal film, with the formation of an electrical contact. The proposed design of the tubular high-temperature fuel cell displays high operational reliability and an extended service life, and allows for increasing the fuel utilization factor and for reducing Ohmic losses. |
