The sensor is used in the anode and cathode low pressure path of an automotive fuel cell PEM (Proton Exchange Membrane). For passenger car, light duty, truck, and off-road application.

Integrating inside the pumping system a pressure sensor can not only ensure a constant pressure when flow rate is The sensor detects deviations from the nominal operating pressure and allow to implement the monitoring functions.

The fuel cell PEM needs humidity to work properly.
Eltek FCEV sensors are freezing proof thanks to the experience on Ad-Blue pressure sensors (in production since 2007, more than 40 Million vehicles equipped with Eltek sensors) and keep on working properly even in case of frozen fluid partially covering the sensitive membrane.
Version with fast temperature response time and combo Pressure & Temperature sensor are available
