A connecting structure of a flat fuel cell assembly. The assembly includes a plurality of fuel cells, each of which has a membrane electrode assembly with an anode, a proton exchange membrane and a cathode combined. Two conductive nets are attached to the surfaces of the anode and the cathode of each membrane electrode assembly by thermosetting adhesive and heat pressing to collect and transmit electrons.
