Photo-rechargeable fuel cell using photo-hydrogenation reactions of quinone molecules

Abstract

We demonstrated new concept photo-rechargeable fuel cell using protonation and de-protonation reactions of quinone molecules. It was found that disodium 9,10-anthraquinone-2,7-disulfonate (AQDS) can work as active quinone molecules of the proposed cell. Photo-induced protonation reaction of AQDS which was confirmed by UV-Vis measurements corresponds to the charge process of the proposed photo-rechargeable cell and the protonated AQDS electrode can work just like a fuel electrode of conventional fuel cell. It was revealed by full-cell experiments that photo-rechargeable fuel cell works practically.
