摘要：

With the aim of increasing the efficiency of an Fe/Cr redox flow battery, the behaviour of the Cr(III)/Cr(II) redox reactions and the hydrogen evolution on gold-graphite electrodes has been studied. Different metals with high hydrogen overvoltage have been used. An enhancement in the reversibility of the redox couple is produced with these types of gold-graphite electrodes, though the energetic efficiency of a monopolar Fe/Cr redox cell constructed with these electrodes is not improved due to the greater hydrogen evolution presented by the gold-graphite electrodes in relation with graphite electrodes.
