摘要： In a solid oxide fuel cell, air supplied from the outside through an air supply port Pain firstly flows through an air supply channel Hain in the downward direction to flow in air channels Sa. The air flowing into the air channels Sa flows through the air channels Sa in the lateral direction to flow out to an air discharge channel Haout. The air flowing out to the air discharge channel Haout flows through the air discharge channel Haout in the upward direction to be discharged to the outside from an air discharge port Paout. When a pressure loss ratio ΔPc/ΔPm, which is a ratio of a pressure loss ΔPc of air generated in the air channel Sa to the pressure loss ΔPm of air generated in the air supply channel Hain (or the air discharge channel Haout) during the operation of a fuel cell (at working temperature), is within 1 to 2500, the flow rate of the air flowing into each air channel can be equalized as much as possible, thereby being capable of preventing the reduction in the output.

摘要： On each of upper and lower surfaces of a flat-plate-like support substrate having a longitudinal direction and having fuel gas flow channels formed therein, a plurality of power-generating elements A connected electrically in series are disposed at predetermined intervals along the longitudinal direction. On each of the upper and lower surfaces of the support substrate, a plurality of recesses are formed at predetermined intervals along the longitudinal direction. Each of the recesses is a rectangular-parallelepiped-like depression defined by four side walls arranged in a circumferentially closed manner and a bottom wall. That is, in the support substrate, frames are formed to surround the respective recesses. Fuel electrodes of the power-generating elements A are embedded in the respective recesses, and inter connectors are embedded in respective recesses formed on the outer surfaces of the fuel electrodes.

摘要： A gripping jig for assembling whereby a force is applied to a molded body in a direction perpendicular to an assembling direction. When an assembling load is applied to the molded body, the force is adjustable with an adjustment screw such that the molded body is guided to move in the assembling direction. Since the force is applied from a direction different from the assembling direction, the molded body can move in the assembling direction, and since the force is adjustable, application of the assembling load to the molded body and the movement of the molded body can be adjusted. Since a plurality of the molded bodies are fixed and assembled respectively, when there are variations in size of the molded bodies, an excessive assembling load is is avoided with each molded body guided to move, so that a more uniform assembling load is applied to the plurality of molded bodies.
摘要翻译： 一种用于组装的夹持夹具，其中在垂直于组装方向的方向上将力施加到成型体。 当组装负载施加到成型体时，可以通过调节螺钉调节力，使得成型体被引导以沿组装方向移动。 由于从与组装方向不同的方向施加力，所以成型体能够在组装方向上移动，并且由于力是可调节的，所以可以调整组装载荷到模制体和模制体的运动 。 由于多个成型体分别被固定和组装，所以当成型体的尺寸发生变化时，避免了每个成型体被引导移动而产生过大的组装负荷，从而使更均匀的组装载荷施加到 多个成型体。
