The invention discloses an elliptical wave-shaped runner structure of a solid oxide fuel cell and an optimization method of the elliptical wave-shaped runner structure, the runner structure comprises a cathode connecting piece, a single cell and an anode connecting piece which are sequentially arranged from top to bottom, the cathode connecting piece is connected with the single cell to form a cathode runner, and the anode connecting piece is connected with the single cell to form an anode runner; the anode connecting piece is connected with the single battery to form an anode flow channel; projections of the cathode flow channels and the anode flow channels on the surfaces of the single cells are rectangular; and the surfaces of one sides, far away from the single cells, of the cathode flow channels and the surfaces of one sides, far away from the single cells, of the anode flow channels are wavy concave-convex curved surfaces. The flow channel structure disclosed by the invention can reduce the pressure drop of the flow channel, improve the non-uniform distribution of gas in the flow channel, improve the mass transfer efficiency, promote heat exchange and improve the performance of the battery.

The present invention relates to the technical field of automobile structural design optimization methods, and specifically refers to a trunk lid bent tube hinge axis arrangement calculation optimization method. According to the rear modeling CAS surface, as well as known design parameters and set constraints, the trunk lid initial opening θ0 and the hinge axis initial coordinate f0 are set; a hinge optimization area is constructed, and within the hinge optimization area, the trunk lid initial opening θ0 and the hinge axis initial coordinate f0 are calculated based on the hinge span design requirements, human-machine goals, the safety gap of the hinge relative to the sealing strip movement, the safety gap requirements of the trunk lid and the rear windshield during the opening process, the assembly space distance between the hinge axis and the rear windshield, and the trunk lid closing force requirements to obtain the optimal solution for the hinge axis. The optimization method of the present invention is reasonably designed, with rich considerations, avoiding the risk of repeated modifications in the later stage, improving the efficiency of the hinge axis design and development, and has great promotion value.
