TY - JOUR TI - Optimization of a fractal electrode-level charge transport model AU - Liu Xian-Yong AU - Liu Yan-Ping AU - Wu Zeng-Wen JN - Thermal Science PY - 2021 VL - 25 IS - 3 SP - 2213 EP - 2220 PT - Article AB - A fractal electrode-level charge transport model is established to study the effect the porous electrodes on the properties of solid oxide fuel cells. A fractal variational principle is used to obtain an approximate solution of the overpotential distribution throughout electrode thickness. Optimal design of the electrode is discussed.
