PURPOSE: To provide a current-transmitting structural element for transmitting a current between a stacked high-temperature fuel cell by forming an element of a porous or impermeable noble metal surface layer and a continuous layer, which is interposed between a support and the noble metal surface layer and which is made of the conductive Cr2 O3 and which works as an oxidization preventing layer and a diffusion barrier at the same time. CONSTITUTION: The element is formed as a collector by forming porous or impermeable noble metal surface layers 9, 12, which exist in the only contact surface and which is made of metal such as Au and Pt or the alloy thereof. A continuous layer 8, which is interposed between supports 7, 10 and the noble metal surface layers 9, 12 and which works as an oxidization preventing layer and a diffusion barrier at the same time and which is made of conductive Cr2 O3 , sequentially. With this structure, a new current-transmitting structural element for transmitting a current between a flat stacked ceramic fuel cell is obtained. |
