Abstract

Die Anmeldung betrifft eine Sensoreinrichtung (1) zur Bestimmung zumindest einer Messgröße, beispielsweise der relativen Feuchte und/oder Temperatur, in der Gasphase eines Gasstroms (5), mit zumindest einem Messfühler (7), welcher in den Gasstrom (5) eintaucht bzw. mit diesem in Kontakt steht. Erfindungsgemäß ist der Messfühler (7) zum Schutz vor im Gasstrom (5) mitgeführten Aerosolpartikeln (6) von einem feinporigen, hydrophoben Schutzkörper (8) abgeschirmt. Die Anmeldung betrifft weiterhin ein Verfahren zur Überwachung eines Brennstoffzellensystems mit zumindest einer Niedertemperatur-Brennstoffzelle, vorzugsweise einer PEM-Brenstoffzelle, im Hinblick auf den Korrosionszustand der mit den Reaktanden der Brennstoffzelle in Kontakt stehenden Elektroden, vorzugsweise der kathodenseitigen Elektrode, wobei kathodenseitig ein O2-hältiges Gas und anodenseitig ein H2-hältiges Brennstoff gas zugeführt wird, dadurch gekennzeichnet, dass die O2-Konzentration im Anodenabgas des Brennstoffzellensystems gemessen wird, während die zumindest eine Brennstoffzelle mit den Reaktanden versorgt wird; dass ein der O2-Konzentration proportionales Sensorsignal gewonnen wird; sowie dass bei Überschreitung eines Schwellwertes des Sensorsignals Gegenmassnahmen zur Absenkung der O2-Konzentration eingeleitet werden.
