Data acquisition system for electrochemical applications

Abstract

A low cost data acquisition system for electrochemical cells has been devised on the basis of the new microprocessor computer generation with IEC-BUS interface connections. This modular structure allows the application and extension of the proposed system to all IEC-BUS† compatible measuring apparatus. Our special interest was focused on the control of experiments with a large data flow like impedance spectroscopy as well as long time experiments like the temperature dependence of a cell e.m.f. Beside this, experiments like d.c.-conductivity, discharge characteristics and current-voltage curves can easily be carried out. The programs have been developed in a way which allows an application of the system in scientific laboratories as well as in the routine quality control of electrochemical device production.
