Abstract: PURPOSE: A direct interior-modified melt carbonate fuel cell is provided, which is provided with a carbonate blocking membrane to increase the lifetime and to improve the efficiency without the increase of internal resistance and the consumption of carbonate. CONSTITUTION: The melt carbonate fuel cell comprises a carbonate blocking membrane which is made of nickel or nickel-containing alloy and blocks the delivery of the hydroxide vapor converted from the carbonate vapor or the carbonates into a catalyst, between a fuel electrode and an interior-modified catalyst layer. Preferably the carbonate blocking membrane contains pores whose mean pore size is 0.01-10 micrometers, by the degree of 30-90 %, and has the thickness of 0.1-1 mm. The carbonate blocking membrane is prepared by coating nickel or nickel-containing alloy on the surface of porous inorganic carrier selected from the group consisting of Al2O3, SiO2, TiO2 and ZrO2.
