Abstract:
1. A current-collecting composite plate for a fuel cell configured with unit cells, comprising: an insulator layer; and a plurality of pairs of conductor layers, the conductor layers being bonded to the insulator layer to be spaced apart from each other by a predetermined distance, each pair being used for adjacently disposed anode and cathode electrodes of a different one of the unit cells by sandwiching an electrolyte assembly therebetween, each conductor layer including: a first conductor layer of a corrosion resistant metal treated with an electrically conductive surface treatment; a second conductor layer of a metal with low electrical resistivity laminated on the first conductor layer; a through-hole penetrating the first conductor layer and the insulator layer; and a connecting portion formed of the second conductor layer for connecting the unit cells.
