Abstract:
1. A sensor for determining a concentration of carbon monoxide in a reducing gas stream as a function of a measured electrical property, said sensor comprising: a. a substrate, said substrate having at least a first side and a second side, said substrate being non-conductive; b. a first electrode, said first electrode deposited on said first side of said substrate, said first electrode adapted to conduct electricity; c. a second electrode, said second electrode deposited on said first side of said substrate so as to not contact said first electrode, said second electrode adapted to conduct electricity; and d. a sensing material, said sensing material in electrical contact with said first electrode and said second electrode, said sensing material comprising a majority of cuprous chloride (CuCl), said sensing material capable of selectively adsorbing carbon monoxide from said reducing gas stream, said sensing material having an electrical property that varies in relation to said adsorbed carbon monoxide on said sensing material.
