Platinum electrode is used as an auxiliary electrode in electrochemical measurements.
It is designed to fit in our universal photoelectrochemical cell.

The bottom part of the electrode is flat, so the capacitance of the electrolyte-electrode layer is possibly large. That helps to separate that capacitance from other capacitances connected in series, like a capacitance of working electrode.

铂电极在电化学测量中用作辅助电极。
其设计适合我们的通用光电化学电池。

电极的底部是平的，因此电解质-电极层的电容可能很大。这有助于将该电容与其他串联电容（如工作电极电容）区分开来。
