Research and Development for High Performance Electrode Materials and Lectrode Structures in Molten Carbonate Fuel Cells

从电化学角度对熔融Li/K碳酸盐的氢氧化和氧还原过程进行了研究。i)动力学参数和反应机理，ii)电极材料的影响，以及iii)多孔气体扩散结构的设计和制造。对金属的腐蚀研究也在无氢熔体中进行。重点介绍了一种新型多孔电极的研制。为制备高性能电极结构，提出了在大孔镍基上制备兰尼合金粉末的复合电解涂层。

Electrochemical stduies on hydrogen oxidation and oxygen reduction processes on molten Li/K carbonates have been carried out from the view points.of i) Kinetic parameters and reaction mechanism, ii)effects of electrode materials, and iii) design and fabrication of porous gas deffusion structures. Corrosion studies on metals were also conducted in the melt without hydrogen. Emphasis was placed on the development of a new type of porous electrode. Composit electrolytic coating of Raney alloy powder on nickel matrices with large pores was proposed for the fabrication of high perpormance electrode strucutures.
