0506 アノードサポート固体酸化物形燃料電池システムの数値計算(S51-2 自然エネルギー,SOFC,S51 分散エネルギー技術)
詳細
A one dimensional simulation model of anode supported tubular solid oxide fuel cell is developed. Simulation result is compared with the experimental data of SOFC with different anode pore structures. Current voltage and AC impedance characteristics are compared with the experimental result The effects of pore structures on ohmic, activataion, and concentration overpotentials are investigated. The pore size and porosity affect anode resistance, gas diffusivity, reaction overpotentials. Addition of pore former increases ohmic overpotentials, which can be attributed to the decrease of the TPB length.
