Structure, and can be abutted against the fuel cell board on both sides. [Prior art] It is known that the flow channel plate of the fuel cell is only provided with a flow field structure on one side thereof, such as a channel. Therefore, the membrane electrode group of the fuel cell can only be affixed on this single side. The combination of the flow channel plate and the fuel cell, for a flat and large-area fuel cell, the area of the flow channel plate must be at least close to the area of the fuel cell, so that each membrane electrode group of the fuel cell can With the supply of fuel, the structure of the conventional flow plate is obviously not suitable for a miniaturized fuel cell device. In view of the lack of a known runner plate, the creator of this creation is eager to improve and create a double-sided runner plate structure. [New content] The main purpose of this creation is to provide a double-sided flow channel plate structure, which forms the flow field structure of fuel on the upper and lower surfaces of the flow channel plate, respectively. Another purpose of this creation is to provide a double-sided flow channel plate structure that can greatly reduce the overall volume of a fuel cell. In order to achieve the above-mentioned purpose of the cost creation, this creation provides a double-sided runner plate structure including: a plate body; an upper groove body and a lower groove body respectively forming the upper surface and the lower surface of the plate body, each of which Setting position of the lower tank
