A hydrogen sensor assembly is disclosed. The hydrogen sensor assembly includes a sensing element within a sensor housing. The sensor housing includes an opening to facilitate a fluid communication between the sensing element and an exhaust stream of a fuel cell. A substantially water-vapor-impermeable membrane is disposed within the opening between the sensing element and the exhaust stream to militate against water vapor from the exhaust stream entering the sensor housing. The sensor housing may include a second opening to facilitate a fluid communication between the sensing element and an external environment to evacuate water vapor generated by the sensing element.
