ABSTRACT:
The present invention relates to a flat fuel cell combining runner plates and a conducting layer. The flat fuel cell includes two runner plates and a conducting layer between the runner plates. There are conducting blocks embedded into the predefined locations on the assembly surfaces of two runner plates. A concave flow passage is shaped by the assembly surfaces of runner plates and the conducting blocks, thus providing a unique structure combining the runner plates and conducting layer. The conducting blocks are electrically connected through the contact of convex flanges on the conducting blocks. Thus, the flat fuel cells are developed thin, making it possible to greatly reduce manufacturing assembly costs without the need of electric wires and to achieve better economic efficiency and applicability.
