Abstract

The effect of ferric ions on cell performance of proton exchange membrane water electrolyzer (PEM WE)was studied by injecting Fe2(SO4)3 solution into DI water to prepare different Fe3+ concentrations contamination (1, 10, 100 parts per million (ppm, molar ratio)). Results showed that there was clear cell performance decay with increasing Fe3+ concentrations, and the cell stopped running at 100 ppm Fe3+ concentration in feed water. With increasing temperature, the cell performance increased for a short period. With low Fe3+ concentrations, cell performance decreased with increasing current density, but with 10 ppm Fe3+ concentration and higher current density of 2A/cm2 , cell performance was enhanced. Therefore, both temperature and current density can make positive contributions to improve cell performance under the condition of contaminated feed water.
