摘要： The operating condition is set so that a phosphoric acid concentration, at which an amount of reaction product water to lower a concentration of phosphoric acid and an amount of water evaporated from phosphoric acid are equilibrated, can be not less than a reference phosphoric acid concentration to maintain desired performance, when a phosphoric acid fuel cell is operated under a condition where the reaction product water exists as liquid water. Specifically, an equilibrium phosphoric acid concentration-setting system is used to control, if necessary, gas flow rate control systems, gas temperature control systems, and pressure control systems so as to effectively prevent the performance of the phosphoric acid fuel cell and its power generation from being worsened. Accordingly, it is possible to suitably operate the phosphoric acid fuel cell at a low temperature without additional equipments.
摘要翻译：操作条件设定为使磷酸浓度降低至磷酸浓度降低的反应产物水量和从磷酸蒸发的水量的磷酸浓度可以不小于参考磷酸浓度当磷酸燃料电池在作为液体水存在反应产物水的条件下操作时，保持期望的性能。具体而言，如果需要，使用平衡磷酸浓度设定系统来控制气体流量控制系统，气体温度控制系统和压力控制系统，以有效地防止磷酸燃料电池的性能及其发电从恶化。因此，可以在没有附加设备的情况下在低温下适当地操作磷酸燃料电池。
