The polarization measuring instrument is for measuring the polarization resistance and the polarization curve of the surface of a metallic material in a solution or a coating applied to the surface of a metal in a solution.
A diagnostic method for an electrochemical fuel cell is described wherein a non-steady state polarization curve is obtained.
A polarization curve of voltage as a function of current may thus be obtained with the entire current sweep lasting less than 20 seconds.
where ΔE and Δi represent the voltage and current increments, respectively, in the linear portion of a polarization curve at i = 0.
A fuel cell equipped with the present electrode substrate will produce a polarization curve which is virtually the same as that produced by a fuel cell equipped with a conventional electrode substrate.
We were also happy to see that the polarization curve, which measures the electrolyzer’s electro-chemical characteristics, is also the same as it was at commissioning.
