A thermophilic anaerobic digester (AD) was combined with a microbial fuel cell (MFC) to evaluate whether either component had increased stability when operated in combination as a hybrid system, perturbed by the addition of acetic acid. The MFC and the anaerobic digester were able to operate effectively together. The MFC was more susceptible to high acetic acid load than the AD. The hybrid system did not have increased resilience compared to the solitary systems in the conditions tested. However, the low pH had a relatively delayed effect on the MFC compared to the AD, allowing the hybrid system to have a more stable energy output. Also, at very low pH, when operating as a hybrid, the AD component was able to recover pH to normal levels when the MFC component failed. These results demonstrate that there are synergies that can be gained from this hybrid system.
采用嗜热厌氧消化器（AD）与微生物燃料电池（MFC）相结合的方式，评估在受到添加乙酸的干扰时，作为混合系统运行时，任一组分的稳定性是否会增强。MFC 和厌氧消化器能够有效地一起运行。与 AD 相比，MFC 更容易受到高乙酸负荷的影响。与单独的系统相比，混合系统在测试条件下并没有增加弹性。然而，与 AD 相比，低 pH 对 MFC 的影响相对延迟，从而使混合系统能够输出更稳定的能量。此外，在非常低的 pH 值下，当作为混合系统运行时，当 MFC 组件失效时，AD 组件能够将 pH 恢复到正常水平。这些结果表明，从这种混合系统中可以获得协同效应。
