本研究的目的是通过实验和模拟来定量地阐明阳极废气再循环（AGR）对以甲烷为燃料的固体氧化物燃料电池（SOFC）性能的改善程度。在实验中，使用能够高精度地模拟AGR条件下的阳极原料气体的装置，测定AGR条件下的市售圆盘型SOFC的发电特性。由于实验是使用无密封结构的电池进行的，因此周围空气可能扩散到阳极中对电池性能产生负面影响。这种可能出现在实验数据中的空气渗透的影响，通过数值模拟进行评估，并考虑。作为实验和模拟的结果，通过进行AGR来评估电池电压的改善，并且定量地讨论了性能改善的因素。
The purpose of this research is to elucidate quantitatively the degree of performance improvement in solid oxide fuel cells (SOFCs) which use methane as a fuel by introducing anode off-gas recycle (AGR) through experiments and simulation. In the experiments, power generation characteristics of a commercially available disc-type SOFC under AGR conditions were measured using an apparatus that can simulate an anode feed gas for AGR conditions with high accuracy. Because the experiments are conducted using the cells with seal-less structure, the possible diffusion of surrounding air into anode negatively affects the cell performance. This effect of air penetration which may appear in experimental data was evaluated by numerical simulation and taken into consideration. As a result of the experiment and the simulation, an improvement of the cell voltage by conducting AGR was evaluated and factors of the performance improvement were quantitatively discussed.
