Zusammenfassung: | The invention provides a bipolar plate of a high-temperature fuel cell, a fuel cell stack and a manufacturing method of the bipolar plate. The bipolar plate comprises a base body and a sealing ring, a plurality of groups of flow channel structures are arranged on the surface of the base body, each flow channel structure comprises a plurality of groups of fine semi-concentric-square-shaped flow channels, the upper semi-concentric-square-shaped flow channels and the lower semi-concentric-square-shaped flow channels are mutually symmetrical to form a concentric-square shape, each group of flow channels is provided with an air inlet and an air outlet, and the flow channels are parallel, are sequentially arranged from inside to outside and are uniformly distributed on the surface of the bipolar plate; the flow channels are communicated through the air inlet and the air outlet; by optimizing the flow channel structure, increasing the effective flow area, increasing the contact area with the carbon paper and reducin |
