ABSTRACT:
There is proposed a molten carbonate fuel cell of high performance and long life which is provided with an oxidizing gas side-collector plate having on its surface a non-stoichiometric composite oxide layer excellent in electric conductivity and corrosion resistance, and hardly attracting electrolyte. This molter carbonate fuel cell comprises a unit cell comprising an electrolyte body formed of a porous body impregnated therein with a carbonate, a cathode disposed on one main surface of the electrolyte body, and an anode disposed on the other main surface of the electrolyte body, corrugated collector plates, disposed alternatively on a surface of the anode and on a surface of the cathode, and interconnectors, each being disposed on a surface of each of the collector plates, wherein the collector plate disposed on the cathode comprises a main body made of austenitic stainless steel, an Fe-Cr-Ni alloy layer covering a surface of the main body and consisting of 23 to 45 wt % of Fe, 12 to 27 wt % of Cr, the balance of Ni and not more than 1 wt % of unavoidable impurities, and a nickel-ferrite-based non-stoichiometric composite oxide layer formed on a surface of the Fe-Cr-Ni alloy layer.
