首次展示了一种聚合物电解质膜水电解槽（PEMWE），它采用由印刷电路板（PCB）制成的分段集电器，并具有光学通道进入通道。该电池可以实时研究局部电流密度、流动状态和气泡形成动力学。观察到从通道起始处的离散气泡流向通道末端的长子弹形气泡的转变，与局部电流密度的显着增加相关。 (C) 2014 Elsevier B.V. 保留所有权利。
A polymer electrolyte membrane water electrolyser (PEMWE) employing a segmented current collector made from a printed circuit board (PCB) with optical access to the channel has been demonstrated for the first time. The cell allows the local current density, flow regime and bubble formation dynamics to be studied in real time. Transition is observed from a flow of discrete bubbles at the start of the channel to long bullet shaped bubbles towards the end of the channel associated with a significant increase in local current density.
