Abstract
A current-collecting composite plate for a fuel cell configured with unit cells according to the present invention, which comprises: 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 for a different one of the unit cells by sandwiching an electrolyte assembly therebetween. And, each conductor layer includes: 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; 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.
