[0042] The present invention will be further described in conjunction with the following examples, but it is not a basis for limiting the present invention.
[0043] A method for simulating the electrolyte interface of SOFC rectangular electrode includes the following steps:
[0044] S01. Model assumptions;
[0045] S02. The geometric object setting of the model;
[0046] S03. By considering the transport equations of electrons, ions and gases in the anode / electrolyte / cathode unit and electrochemical reaction kinetics, use COMSOL software to establish a two-dimensional numerical model;
[0047] S04. Compare the performance and internal physical field distribution of rectangular anode / electrolyte interface batteries and planar interface batteries with different heights, analyze the results and draw simulation conclusions.
[0048] Further, in the step S02, the geometric object of the model is set as an anode-supported solid oxide fuel cell with an electrolyte thickness of 10 μm.
