A sensor to detect gases and vapors, particularly carbon monoxide and water vapor, at relatively low concentrations includes a substrate having a layer on a face of the substrate. The layer comprises a semi conductor metallic oxide (such as stannic oxide), a catalyst (such as platinum black), and a

โฆ Synopsis
Thin-film electrocatalyst layers with varying PTFE and Nafion contents for unitized regenerative PEM fuel cells (URFCs) made using the paste method were examined as URFC electrodes. Adding Ir catalyst to the oxygen electrode layer significantly improved performance. Catalyst loadings can be reduced to <1/3 using this method.
