We report an Ir complex as an anode catalyst capable of switching between a hydrogenase-type fuel-cell mode and a photosystem II-type solar-cell mode. This catalyst is connected to carbon-black-supported platinum as a cathode catalyst, which reduces dioxygen in a manner analogous to cytochrome c oxidase. Together, they make a system capable of switching between the two modes.
