The double catalyst structure on two mieroheaters of a thermoelectric device was suggested to improve selectivity of the hydrogen for the mixed gas of H2 and CO. Thermoelectric hydrogen sensor (THS) burns and detects both of H2 and CO when these were mixed. Moreover, if we can eliminate the heat contribution of CO, only the H2 concentration can be estimated ever for these mixture gases. The noble structure of double catalysts, a CO seleetive Au/Co3O4 catalyst and a H 2 selective Pt/Al2O3 integrated on the two mieroheaters were fabricated and its gas sensing performance was investigated.
