Abstract

A porous electrode structure for a gas sensor, as well as a sensor arrangement, is provided for detecting hydrocarbons in a measured gas. The porous structure guarantees, in addition to a low impedance, a high temporal stability and reproducibility of the measurement signal. The porous electrode structure has a conductive gold framework, which contains oxide components, in particular gallium oxide.
