摘要

Abstract

Electrochemical impedance spectroscopy (EIS) is widely used in fuel cell impedance analysis. However

for ohmic resistance (

)

EIS has some disadvantages such as long test period and complex data analysis with equivalent circuits. Therefore

the current interruption method is explored to measure the value of

in direct methanol fuel cells (DMFC) at different temperatures and current densities. It is found that

decreases as temperature increase

and decreases initially and then increases as current density increases. These results are consistent with those measured by the EIS technique. In most cases

the ohmic resistances with current interruption (

) are larger than those with EIS (

EIS

)

but the difference is small

in the range from-0.848% to 5.337%. The errors of

at high current densities are less than those of

EIS

. Our results show that the

data are reliable and easy to obtain in the measurement of ohmic resistance in DMFC.
