摘要: Abstract A small amount of cerium added to Ni Cr anode electrode in a molten carbonate fuel cell (MCFC) and its effects on sintering creep resistance were then investigated by comparing it with Ce-free electrodes. The Ce anodes was better than that between 500 600 °C. However, they exhibited slightly weaker Cr-free at higher temperatures effect addition electrodes observed strain porosity change after the test. exactly proportional Ce. This believed be result making more ductile, which lead an enhancement deformation caused simultaneous application both high pressure temperatures. Therefore, present study presents possibility rare-earth metals (Ce) can materials MCFC improve resistance.
