ABSTRACT:
A molten carbonate fuel cell of high performance and long life, which is capable of preventing the corrosion at the contacting portion between collector plates (in particular, an oxidizing gas-side collector plate) and the interconnector so as to suppress an increase of contact resistance. This molten carbonate fuel cell comprises, a unit cell comprising an electrolyte body formed of a porous body impregnated therein with a mixed carbonate containing two or more kinds of carbonate mixed in a desired mixing ratio, 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, each disposed on a surface of the anode and on a surface of the cathode, and interconnectors, each disposed on a surface of each of the collector plates, wherein a substance which is capable of reacting with the mixed carbonate at an operation temperature of the fuel cell thereby to change a composition ratio of the mixed carbonate is deposited on a surface of at least one member selected from the collector plate and the interconnector.
