A gas sensor includes a housing () having disposed therein a membrane electrode assembly comprising a sensing electrode (), a counter electrode (), and a solid polymer electrolyte () disposed between the sensing electrode and the counter electrode. The sensing electrode comprises a first catalyst comprising noble metal nanoparticles (). The counter electrode comprises a second catalyst comprising noble metal nanoparticles (), which can be of the same composition or a different composition as the first catalyst. The sensor housing also includes an opening () in fluid communication with the sensing electrode for test gas to contact the sensing electrode. The sensor also includes an electrical circuit () connecting the sensing electrode and the counter electrode.
