Three-dimensional dynamic modeling and transport analysis of solid oxide fuel cells under electrical load change

[Display omitted] •SOFC operation at potentiodynamic conditions was temporally and spatially resolved.•Excessive response and relaxation time of electrical current was observed.•Electrochemical reaction zone reacts instantaneously to electrical load change.•Species transport in anode shows time-dela...
