近年来，阳极气体循环（AGR）作为sofc的一种提高效率的方法备受关注。然而，由于实验的复杂性，sofc在AGR条件下的性能还没有得到充分的评估。本文通过实验研究了引入AGR对SOFCs的影响。为了方便实验，我们研制了一种既能方便地合成AGR条件下的重整气，又能合成无AGR条件下的重整气的装置。通过该装置，定量地阐明了引入AGR的效率增益，比较了在高燃料利用率条件下，有无AGR条件下SOFC的性能。此外，还研究了AGR SOFC性能与燃料利用率的关系。本文将详细介绍这些结果。
Recently, anode gas recycle (AGR) is spotlighted as one of the efficiency-enhancing methods on SOFCs. However, performance of SOFCs under AGR conditions has not been sufficiently evaluated, because of experimental complexity. In this work, an influence on SOFCs by introducing AGR is investigated experimentally. In order to facilitate experiment, we developed equipment which can easily synthesize reformate gases of both AGR and no AGR conditions with high accuracy. By using this equipment, an efficiency gain by introducing AGR is quantitatively elucidated, comparing SOFC performance between with and without AGR conditions under high fuel utilization. In addition, dependency of AGR SOFC performance on fuel utilization is also investigated. This paper will present details of these results.
