Even small traces of carbon monoxide in the fuel gas lead to a degradation of performance in low temperature polymer electrolyte membrane (PEM) fuel cell systems. Therefore a sensor which is capable of detecting CO in a ppm range in a hydrogen rich atmosphere is a great advantage. In this talk a new gas sensitive layer to be used as suspended gate in an existing CCFET based sensor system is presented. The new gate material...
