(Photo-)electrochemical water splitting is a key process in storage and utilization of renewable energies in the upcoming energy scenario. While the technology readiness level of polymer electrolyte membrane water electrolysis (PEMWE) is high at it’s current stage photoelectrochemical water splitting has still a long way to go. Both technologies suffer hereby from the slow kinetics and and harsh oxidative conditions at the anode which lead to materials degradation.
My work revolves around the degradation mechanisms of (photo-)electrochemical anode materials. Using an electrochemical scanning flow cell (SFC) coupled to an inductively coupled plasma mass spectrometer (ICP-MS) I am able to detect dissolution products and connect degradation to electrochemical operation modes. Furthermore my work involves uncovering the differences of degradation in fundamental studies compared to degradation in operational systems.
