摘要： Excellent gas sealing properties were difficult to achieve with a structure that uses a meal material to control material cost and does not increase the number of components. A cell is configured by using a metal separator having at least one protruding structure between a manifold and an electrode channel, and having a communicating channel structure that forms a fluid circulating space by being folded back at the side containing a connection so that the tip of the protruding structure is in contact with a surface of the separator. Accordingly, a gas channel from the manifold to an electrode surface can be easily formed integrally. This can be applied to a metal material easily. Further, the present invention can provide excellent gas sealing properties.

摘要： There is provided a mold component which makes it possible to mold a substrate for an optical recording medium which enables a functional layer having a uniform thickness to be formed thereon without using a resin-coating assisting member. A stamper holder holds a stamper thereon, and has a generally hollow cylindrical shape. An insertion hole formed through a central portion of the stamper has a diameter which is larger than an outer diameter of a cavity-side end of the stamper holder at a higher temperature of the holder than a normal temperature, and is slightly smaller than the outer diameter at the normal temperature of the holder. The cavity-side end inserted into the insertion hole at the higher temperature of the stamper is grasped by a rim of the insertion hole which is reduced in diameter at the normal temperature of the stamper.
