熔融碳酸盐燃料电池 (MCFC)是一种通过氢或矿物燃料的氧化将化学能直接转化成电能的能源转化装置 .目前电池一般由含Cr量为 2 - 10 % (mass)的多孔Ni-Cr合金阳极、LiAlO2 电解质板及多孔NiO阴极组成 .单体电池间通过材质为Fe或Ni基合金的金属双极板串联连接 .目前MCFC已达MW级水平 ,但主要电池材料的腐蚀极大地阻碍了其商业化应用 .MCFC中的腐蚀主要表现为 2种形式 ,即NiO阴极的溶解和金属部件如双极板的腐蚀 .目前已有不少有关MCFC材料腐蚀的研究报道 ,但对其腐蚀机制仍未完全澄清 .本文综述这方面的研究进展 。
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.
