    • The invention concerns ametallic element for a high tem- perature fuel cell stack, wherein each individual fuel cell comprises an anode, a cathode, an electrolyte and an elec- trochemically active area. The metallic element (1) com- prises a metallic sheet (2) having first and second planar surfaces (3,4) on opposite sides of the metallic sheet (2) and a first, second, third and fourth periphery (5,6,7,8), the first and third peripheries (5,7) and the second and fourth peripheries (6,8) forming opposing peripheries. The metallic sheet (1) is provided with inlet and outlet gas openings (99,100) extending completely through the metallic sheet from the first planar surface (3) to the second pla- nar surface (4) and positioned at first and third peripher- ies (5,7) only of the metallic sheet (2), at least one inlet gas opening (99) and at least one outlet gas (100) opening being partially open and extending into one or more micro channels (13) located on the first planar surface (3). Each micro channel (13) extends continuously or dis- continuously from the at least one inlet gas opening (99) or at least one outlet gas opening (100) adjacent to the electrochemically active area of the fuel cell. This metal- lic element ensures an improved flow distribution of gases taking part in electrochemical reactions within the fuel cell, and it is well suited for use as an interconnect in a solid oxide fuel cell (SOFC) or a solid oxide electrolysis cell (SOEC).
    • 本发明涉及用于高温燃料电池堆的非金属元素,其中每个单独的燃料电池包括阳极,阴极,电解质和电化学活性区域。 金属元件(1)包括在金属片(2)的相对侧上具有第一和第二平面(3,4)的金属片(2)和第一,第二,第三和第四外围(5,6 ,7,8),第一和第三外围(5,7)以及形成相对的外围的第二和第四周边(6,8)。 金属片(1)设置有从第一平面(3)到第二平面(4)完全延伸穿过金属片的入口和出口气体开口(99,100),并定位在第一和第三外围 (5,7),仅有金属片(2),至少一个入口气体开口(99)和至少一个出口气体(100)开口部分地开口并延伸到位于所述金属片材上的一个或多个微通道(13)中 第一平面(3)。 每个微通道(13)从邻近燃料电池的电化学活性区域的至少一个入口气体开口(99)或至少一个出口气体开口(100)连续地或不连续地延伸。 该金属元素确保了燃料电池中参与电化学反应的气体的改善的流量分布,并且非常适合用作固体氧化物燃料电池(SOFC)或固体氧化物电解池(SOEC)中的互连, 。
