A one-compartment HO photofuel cell (PFC) with a photoanode based on InGaN nanowires (NWs) is introduced for the first time. The electrocatalytic and photoelectrocatalytic properties of the InGaN NWs are studied in detail by cyclic voltammetry, current versus time measurements, photovoltage measurements, and electrochemical impedance spectroscopy. In parallel, IrO (OH) as the co-catalyst on the InGaN NWs is evaluated to boost the catalytic activity in the dark and light. For the PFC, Ag is the best as the cathode among Ag, Pt, and glassy carbon. The PFC operates in the dark as a conventional fuel cell (FC) and under illumination with 25% increased electrical power generation at room temperature. Such dual operation is unique, combining FC and PFC technologies for the most flexible use.
首次介绍了一种具有基于氮化铟镓纳米线（NWs）光阳极的单室光燃料电池（PFC）。通过循环伏安法、电流与时间测量、光电压测量和电化学阻抗谱详细研究了氮化铟镓纳米线的电催化和光电催化性能。同时，评估了作为氮化铟镓纳米线助催化剂的IrO(OH)，以提高其在黑暗和光照下的催化活性。对于该光燃料电池，在银、铂和玻璃碳中，银作为阴极效果最佳。该光燃料电池在黑暗中作为传统燃料电池（FC）运行，在室温下光照时发电功率提高25%。这种双重运行方式独具特色，将燃料电池和光燃料电池技术结合起来，实现了最灵活的应用。
