摘要： The invention provides a solid oxide fuel cell stack, which comprises an upper current collector plate (1), a lower current collector plate (2) and a stack structure (3) accommodated between the upper current collector plate (1) and the lower current collector plate (2), wherein the stack structure (3) includes at least two connectors (11) and a cell plate (12) disposed between the two adjacent connectors (11) which have an anode side and a cathode side. An oxidant gas seal member (13) is provided at the anode side of the connector (11), and a fuel gas seal member (14) is provided at the cathode side of the connector (11). A hermetic oxidant gas supply passage, a hermetic fuel gas supply passage, a hermetic fuel gas discharge passage and open oxidant gas discharge passages are set in the stack structure (3). Compared with the prior art, the inner gas pressure difference is smaller, and the flow is smoother due to the open oxidant gas passages, thereby effectively solving the problem of the mutual leakage between fuel and oxidant gas, increasing the seal reliability of the stack, and improving the stack manufacturing yield and the stability of operation performance.
