제목 | Enhancement using hydrogen for pre-treatment on nano Aluminum reinforced α-LiAlO2 for MCFC |
초록 | Molten Carbonate Fuel cell (MCFC) entered the stage of commercialization. The important things for the commercialization are long term operation and cost reduction. During long term operations, Cracks which are main problems to lead low performances occurs. To prohibit from occurring Cracks, enhancements of Mechanical strength are significant issues. In this study, we used Aluminum nano powder (100nm) for reinforced-matrix that can cover LiAlO2 Powers. We also added Li2CO3 to prevent consumption of lithium ion.We changed the pretreatment schedule that we put hydrogen Instead of putting air during pretreatment. Hydrogen makes nano aluminum particles to form neck formation easier, and to be sintered.Reinforced-α-LiAlO2(0.631Kgf/mm2) increased mechanical strength dramatically, which is three times compared with using pure α-LiAlO2 (0.214Kgf/mm2). As a result, performances and analyses will be presented in single cell test with hydrogen pretreatment and nano Aluminumreinforced α-LiAlO2 added Li2CO3. |
