摘要
A gas sensor in one form comprises a housing including a base and a top defining an interior space. The housing includes a gas entry hole and first and second electrical terminals. First and second electrodes in the housing interior space each comprise a membrane having a layer of platinum black catalyst on one side. The second electrode includes a lower amount of platinum black catalyst than the first electrode. A separator is placed between the first and second electrodes. Current collectors electrically connect the first and second electrodes to the respective first and second electrical terminals whereby sensor current represents concentration of gas while minimizing cross sensitivity.
