摘要

•EIS measurements under different DC biases in fuel-cell and electrolysis modes were conducted.•The performance and degradation mechanisms of the two modes were investigated by EIS analysis.•Ni non-percolating, Ni coarsening and change of pore morphology in the fuel electrode were revealed by post-mortem analysis.•The dominant performance evolution mechanism in different stages was proposed.
