CORROSION AND PROTECTION FOR MOLTEN CARBONATE FUEL C ELL
熔融碳酸盐燃料电池材料的腐蚀与防护

Molten carbonate fuel cell (MCFC) is an energy conversion device that converts chemical energy into electricity by oxidation of hydrogen or fossil fuels. The state-of-the-art MCFC consists of a porous anode made of nickel with 2 to 10%Cr chromium, a matrix tile of LiAlO 2 and a porous in situ oxidized and lithiated nickel oxide cathode. The cells are connected in series by metal bipolar plates usually made of Fe or Ni-based alloys. The development of the MCFC has reached the MW-scale pilot plant stage, but the corrosion problems of major materials greatly inhibit the commercial applications of the MCFC. Corrosion in the MCFC takes two principal forms, i.e. the dissolution of NiO cathode and the corrosion of hardware such as separator plates. Despite the relatively many papers, the corrosion mechanism in the MCFC still continues to be not fully understood. Present paper reviewed the research progresses in corrosion and protection of the anode, cathode and bipolar plates of the MCFC. Some problems yet to be elucidated were suggested.
