    Abstract: A fuel electrode for a molten carbonate fuel cell(MCFC), a method for preparing the fuel electrode, and a method for directly modifying the inside of an MCFC are provided to prevent the deterioration of the performance of MCFC when ethanol is used as fuel directly by modifying ethanol. A fuel electrode comprises 4-6 wt% of a catalyst layer supported by a metal oxide which is coated on a fuel electrode. Preferably the catalyst layer is nickel(Ni), cobalt(Co), iron(Fe), copper(Cu), platinum(Pt), palladium(Pd), ruthenium(Ru) or rhodium(Rh), is porous and has a thickness of 140-160 micrometers. The inside of a molten carbonate fuel cell is directly modified by injecting an ethanol solution and a carrier gas into the fuel cell. Preferably the carrier gas is N2, He or Ar; and the direct modification is carried out at a temperature of 600-700 deg.C.
