| 英文摘要 | a methanol concentration sensor based on twin nation membrane electrode assemblies (meas) was constructed and characterized by electrochemical methods. pulsed amperometric detection (pad) method, using a low frequency (67 mhz) potential waveform of e(red) (cathodic activation potential)= -0.2 v, e(pre-oxd) (anodic pre-oxidation potential) = +0.60 v and e(det) (detection potential) = +0.80 v versus dhe with the same pulse width of 5 s was applied to the sensor to enhance its performance. the response in pulsed mode had better linearity over a wider concentration range than that in potentiostatic mode. furthermore, using this pad method, the stability of the sensor was enhanced significantly with a slightly linear degradation rate of 2.9 ma h(-1) during long-time test. the performances of the sensor in terms of linearity, low anodic saturation and high stability show its potential application for direct methanol fuel cells.
