Additionally, the in situ generation of Ni(IV) facilitates the structural reorganization of PDA in the photoelectrochemical system, further enhancing the stability of the PDA matrix. The findings of PDA photodegradation, its autonomous metal ion capture within photoelectrochemical systems, and the rapid deactivation of BPNi photoanodes caused by vanadium (V) ions have all provided significant guidance for the enhancement of PDA.

Nevertheless, solid oxide fuel cells presently rely on significant use of several critical raw materials to enable optimized electrode reaction kinetics. This challenge can be addressed by using thin-film electrode materials; however, this is typically accompanied by complex device fabrication procedures as well as poor mechanical/chemical stability. In this work, we conduct a systematic study of a range of promising thin-film electrode materials based on vertically aligned nanocomposite (VAN) thin films. We demonstrate low area specific resistance (ASR) values of 0.44 cm<sup>2</sup> at 650 °C can be achieved using (La<sub>0.60</sub>Sr<sub>0.40</sub>)<sub>0.95</sub>Co<sub>0.20</sub>Fe<sub>0.80</sub>O<sub>3</sub>-(Sm<sub>2</sub>O<sub>3</sub>)<sub>0.20</sub>(CeO<sub>2</sub>)<sub>0.80</sub> (LSCF-SDC) thin films, which are also characterized by a low degradation rate, approximately half that of planar LSCF thin films.

By demonstrating such competitive performance using thin-film cathode functional layers, this work also paves the way for further cost reductions in solid oxide fuel cells, which could be achieved by likewise applying thin-film architectures to the anode functional layer and/or current collecting layers, which typically account for the greatest materials cost in solid oxide fuel cell stacks.
