摘要： The object is to suppress degradation of the durability of an electrolyte membrane caused by deformation by expansion and contraction of the electrolyte membrane. A controller 150 calculates a humidity P of an electrolyte membrane 112 based on a cell resistance value (step S11) and determines whether the humidity P of the electrolyte membrane 112 is less than a humidity threshold A (step S12). When the humidity P is less than the humidity threshold A, the controller 150 determines that a dimensional change rate of the electrolyte membrane is not greater than a predetermined value and performs a process of increasing the humidity of the electrolyte membrane 112 (step S13). The predetermined value is a dimensional change rate that is unlikely to have damage by drying stress. This enables the electrolyte membrane 112 to be humidified before the electrolyte membrane 112 is excessively dried and thereby suppresses tensile stress from being applied to the electrolyte membrane 112 by drying of the electrolyte membrane 112. Accordingly this suppresses cracking and thinning of the electrolyte membrane 112 and improves the durability of the electrolyte membrane 112.
摘要翻译：其目的在于抑制由电解质膜的膨胀和收缩引起的变形引起的电解质膜的耐久性的劣化。控制器150基于电池单元电阻值计算电解质膜112的湿度P（步骤S11），并确定电解质膜112的湿度P是否小于湿度阈值A（步骤S12）。当湿度P小于湿度阈值A时，控制器150确定电解质膜的尺寸变化率不大于预定值，并执行增加电解质膜112的湿度的处理（步骤S13）。规定值是不易因干燥应力而损伤的尺寸变化率。这使得电解质膜112在电解质膜112过度干燥之前能够被润湿，从而抑制了通过电解质膜112的干燥施加到电解质膜112上的拉应力。因此，这抑制了电解质膜112的裂纹和变薄，改善电解质膜112的耐久性。
