The present invention relates to high-temperature solid oxide fuel cells, in particular to rotationally symmetrical high-temperature solid oxide fuel cells. The inventive oxide-ceramic high-temperature fuel cell having one or more gas channel(s) open at at least one end. The fuel cell has a substrate surrounding the gas channel(s) at least sectionally, preferably completely. The gas channel(s) and/or the substrate surrounding the gas channel(s) has/have (a) changing cross-sections(s), preferably (a) conically tapering cross-section(s), seen in the direction of the longitudinal axis/axes of the gas channel(s).

Oxide-ceramic high-temperature fuel cell

The present invention relates to a fuel cell system, in particular solid oxide fuel cell system (SOFC-System), with several tubular fuel cells, whereby several of these fuel cells respectively have at least one inner electrode, an electrolyte surrounding this/these inner electrode(s) at least in sections and at least one outer electrode surrounding the electrolyte at least in sections, so that the electrolyte spatially separates the inner and the outer electrode(s) from each other, at least two of these fuel cells are located or fixated in or on an electrically conducting carrier and/or contact, which connects&#x2014;electrically conducting&#x2014;the inner electrode(s) and/or one/several electrical contact(s) of one/several inner electrode(s) of a first tubular fuel cell or a part of such with the outer electrode(s) and/or one/several electrical contact(s) of one/several outer electrode(s) of a second tubular fuel cell or a part of such, whereby the second tubular fuel cell is preferably located directly adjacent to the first tubular fuel cell or to the part of this fuel cell.

Fuel cell stack

Fuel cell system with at least one burner that is arranged directly at a fuel cell, shaped at/on it, or in which a burner () is a separate element of a fuel cell system with more than one fuel cell () and this burner possesses the structure of a fuel cell or of a sealing element () of a fuel cell.
