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.

Fuel cell system with wetness sensor

A method of conserving energy during a heating event wherein a coolant is heated in a cooling system is disclosed. The method includes establishing a first set point temperature for a first point in the cooling system and establishing a second set point temperature lower than the first set point temperature for a second point in the cooling system. Normally, the coolant is maintained at the second set point temperature at the second set point in the cooling system. During the heating event, the second set point temperature is raised to substantially match the first set point temperature to reduce necessary heating of the coolant at the first point.

Switchable radiator bypass valve set point to improve energy efficiency

A fuel cell hydration system comprising a first reservoir is provided. The first reservoir is positioned between a cathode supply and a fuel cell stack. The first reservoir includes corrugated regions positioned axially along the first reservoir to accumulate water discharged from a first fluid stream. The first fluid stream absorbs the accumulated water when an amount of water within the first fluid stream is below a water level to hydrate the fuel cell stack.

System and method for hydrating a proton exchange membrane fuel cell

A flush and fill process is used to ready a fuel cell cooling circuit for initial use. An external flushing system releasably connected to the cooling circuit circulates flushing coolant through the cooling circuit to remove contaminants from the wetted surfaces of the cooling circuit before the fuel cell is put into use. The flushing system includes a pump for circulating the flushing coolant through the cooling circuit, filters for removing contaminants from the coolant and a heater for elevating the temperature of the coolant. Following the flushing process to remove contaminants, the flushing system is disconnected from the cooling circuit and the cooling circuit is filled with fresh coolant.
