The purpose of the present application includes an electrolyte element 104 between a fuel flow guiding arrangement fuel solid oxide cell body, the cell is a fuel-side 100, the oxygen enriched side 102 and the fuel side and the oxygen-rich side, and wherein the arrangement body, said electrolyte element 104 into and from the oxygen-rich side of the means for guiding the gas, each of the cell flow field plate 121 so as to arrange the flow in the cell, the flow on the flow field plate 121, the distribution zone 120, , and a flow outlet region 131 on the flow field plate 121. The fuel flow guiding arrangement comprises means (123) for guiding the fuel supply flow to the flow distribution zone 120 from the sides 127 of the fuel cell, and the flow distribution on the arrangement electrolyte element 104 fuel supply flow and the at least one geometric shape of the means 125 for rotating the at least one fuel outlet flow of said fluid exit region 131, the fuel flow control structure of the flow distribution region 120 so as to equalize the the fuel supply flow and the fuel outlet fuel flow control structure having at least one geometric shape 124 for essentially uniformly adjusted in at least one of the flow across the electrolyte element 104 based on the functional effect of the flow of the It comprises 122.
