I've attached a picture that shows the relationship between temperature and the amount of saturated vapor for water content. It indicates that as the temperature increases, the amount of saturated vapor decreases.

For example, at room temperature, the saturated vapor is 14, while at 80 degrees, it is 10.

Since in a PEM fuel cell, the operating temperature is between 60 to 80 degrees, does this mean that to avoid liquid water formation, we should ensure the water content of the membrane stays below 10, or at least not higher than 10?
