A three-dimensional numerical model was proposed for double cathode solid oxide fuel cells based on the thermo-electro-mechanical-chemical multi-physics coupling theory. A novel I-type cathode flow channel with an enhanced mass transfer capability was developed. The gas flow velocity, oxygen molar fraction, pressure loss, temperature, stress distribution, and electrochemical properties of the I-type cathode flow channel and the conventional Z-type cathode flow channel were investigated. The results show that compared to the conventional Z-type flow channel, the optimized cathode flow channel has more uniform distribution of oxygen and less pressure loss in the gas flow, and the loss of concentration polarization reduces with the decrease of working voltage.
