| 英文摘要 | alkali-resistant ni/sio(2)-sil-1 and ni/al(2)o(3)-sil-1 core-shell catalysts were prepared for use in direct internal reforming molten carbonate fuel cell (dir-mcfc). a thin zeolite shell was grown on the surface of catalyst beads to create a diffusion barrier against alkali poisons in the vapors generated from the electrolyte during dir-mcfc operation. the synthesis of low defect zeolite shell was investigated and the effects of shell thickness on catalyst activity were examined. a mathematical model of the reaction and alkali-poisoning was developed and the optimum zeolite shell thickness was determined. the experimental and modeling results demonstrated that the core-shell catalyst is more resistant to alkali poisoning and a zeolite shell thickness of 3.5 mu m can protect the catalyst for at least 100 h following a failure of the anode barrier in dir-mcfc to give sufficient time for repair.
