Instrumentation for recording accelerated Tafel plots with x-y recorder

Abstract

An instrument for recoding accelerated Tafel plots with an X-Y recorder is described. The novel feature of this instrument is an analogue time expansion circuit that peemits the potential-time transient, resulting from the impositions of exponentially decaying current on to the electrochemical cell, to be recorded on an X-Y plotter which has a rather long response time.
