| 摘要 |
The invention relates to an electricity generating electrochemical device of the solid-oxide fuel-cell stack type, which comprises: a planar assembly (10) consisting of at least one electrochemical cell (11) comprised between first and second gas diffusing plates (12, 13) made of ceramic of expansion coefficient comprised between 8×10-6 K-1 et 14×10-6 K-1 and drilled with equidistant holes (14, 15); first and second electrically conductive metal grilles (16, 17) each connected to a conductive wire (18, 19) allowing current to flow out of the device, said grilles being placed on either side of said at least one electrochemical cell (11) between this cell and each of the first and second gas diffusing plates; and clamping means (20, 21) mechanically holding this planar assembly (10) together. |
