ABSTRACT　In this article ,the elect rochemical performance of Pd - Ag alloy elect rode in KOH alka2 line solution was studied. The reaction mechanism of Pd( Pd - Ag) - H2 system was discussed and the quantitative relationship between sensor response and hydrogen content was acquired. Pd - Ag alloy elect rode is suitable for using as selective catalytic anode of hydrogen sensor. The elect rochemical hy2 drogen sensor based on Pd - Ag alloy anode exhibit s high sensitivity and good repetition.
