Platinum: A key element in electrode composition for reversible chloralkaline electrochemical cells

In this work, the performance of a reversible electrochemical cell using three different electrodes (Ti/Ru0.5Ir0.5O2, Ti/Ru0.3Ti0.7O2, and Ti/Ru0.3Ti0.6O2Pt0.1) is evaluated and compared for the oxidation of chlorides and reduction of chlorine. Results indicate that this technology is successful and...

Results indicate that this technology is successful and that its efficiency depends significantly on the composition of the electrode in charge of the chlorine electrochemistry.

The best performance is shown by the Ti/Ru0.3Ti0.6O2Pt0.1 electrode resulting from its roughest morphology and the presence of Pt. In shifting from electrolyzer to fuel cell mode, the current produced is rapidly stabilized for Ti/Ru0.3Ti0.6O2Pt0.1 and Ti/Ru0.5Ir0.5O2 electrodes.

Los resultados indican que esta tecnología es exitosa y que su eficiencia depende significativamente de la composición del electrodo a cargo de la electroquímica del cloro . Operando a 0,5 V nos permite obtener cerca de 7 mA cm −2y eficiencias energéticas de alrededor de 120 Wh mmol- 1 de hidrógeno suministrado. En modo electrolítico se pueden obtener eficiencias en torno a 4 mol Cl 2 mWh− 1 . El electrodo Ti/Ru 0.3 Ti 0.6 O 2 Pt 0.1 presenta el mejor comportamiento debido a su morfología más rugosa ya la presencia de Pt. Al pasar del modo electrolizador al modo de pila de combustible, la corriente producida se estabiliza rápidamente para los electrodos Ti/Ru 0,3 Ti 0,6 O 2 Pt 0,1 y Ti/Ru 0,5 Ir 0,5 O 2 . Sin embargo, el electrodo Ti/Ru0.5 Ir 0.5 O 2 mostró un cambio progresivo, lo que sugiere un cambio en su composición que afecta negativamente al sistema.Elsevier202220222021info:eu-repo/semantics/articleapplication/pdfapplication/pdfhttps://hdl.handle.net/10578/30057reponame:RUIdeRA.
