NOVELTY - The current-collecting composite plate for fabricating a fuel cell configured with unit cells, comprises an insulator layer (2), and pairs of conductor layers, which are useful for adjacently disposed anode and cathode electrodes of a different one of the unit cells by sandwiching an electrolyte assembly between the electrodes. The conductor layers are bonded to the insulator layer to be spaced apart from each other by a predetermined distance. Each conductor layer includes a first conductor layer (5a) of a corrosion resistant metal treated with an electrically conductive surface treatment.    USE - The current-collecting composite plate is useful for fabricating a fuel cell configured with unit cells (claimed), where the fuel cell includes a direct methanol fuel cell, phosphoric acid fuel cell, molten carbonate fuel cell, solid oxide fuel cell and polymer electrolyte fuel cell, which is useful as power sources for automobiles, homes, mobile devices and un-interruptible power supply systems.    ADVANTAGE - The current-collecting composite plate is capable of economically and effectively fabricating a thin and compact fuel cell with excellent corrosion resistance, excellent durability, low internal resistance and high power generation efficiency by preventing a degradation of the fuel cell due to dissolution of metallic ions.    DETAILED DESCRIPTION - The current-collecting composite plate for fabricating a fuel cell configured with unit cells, comprises an insulator layer (2), and pairs of conductor layers, which are useful for adjacently disposed anode and cathode electrodes of a different one of the unit cells by sandwiching an electrolyte assembly between the electrodes. The conductor layers are bonded to the insulator layer to be spaced apart from each other by a predetermined distance. Each conductor layer includes a first conductor layer (5a) of a corrosion resistant metal treated with an electrically conductive surface treatment, a second conductor layer (5b) of a metal with low electrical resistivity laminated on the first conductor layer, a through-hole (4) penetrating the first conductor layer and the insulator layer, and a connecting portion (7) formed of the second conductor layer for connecting the unit cells. The conductor layer for the anode electrode of a first unit cell is connected to the conductor layer for the cathode electrode of a second unit cell by the connecting portion. The second conductor layer is formed in a mesh pattern. An INDEPENDENT CLAIM is included for a fuel cell fabricated using the current-collecting composite plate.
