Abstract

A fuel cell system may have at least one sensor including a pair of electrodes disposed on a substrate. The sensor may be configured to produce an output signal having a magnitude that is proportional to a relative humidity in a vicinity of the sensor and, if liquid water is on the sensor, proportional to an amount of the liquid water on the sensor.
