Abstract
The present invention relates to an electrochemical gas sensor that includes a first planar substrate having at least one planar electrode formed thereon, thereby forming a first electrode assembly, and a housing defining a reservoir which, in use, contains liquid electrolyte for contacting the electrode(s). The housing has a first sealing face to which the first electrode assembly is sealed, the sealing face having conducting portions electrically isolated one from another. A portion of at least one electrode is in contact with a respective conducting portion so as to provide a means of external electrical connection to the electrode(s). The conductive portions and non-conductive portions of the housing are co-moulded. This sensor has a relatively small number of component parts and is relatively cheap and easy to manufacture. It also provides a cheap and reliable way of forming external electrical connections to the electrodes.
