抄録	High-performance attractive SOFC anode material Ni-GDC-nanocube core-shell composites were successfully fabricated in a solution by chemical reduction method.

In situ fabrication of Ni-Ni necking framework was achieved by crystal growth of Ni spheres during generation tests even at 500℃ operating. The non-sintered Ni-GDC-nanocube core-shell anode showed a higher power density compared with conventional Ni-GDC-anodes sintered at 1300℃.The designated macro-and microstructure of Ni-GDC core-shell anodes were maintained after generation testd even at 700℃ operating.
