A bipolar electrode is quite unconventional as it behaves simultaneously as an anode and a cathode in contrast to a classic electrochemical setup where the electron transfer reactions are promoted on two different electrodes. The driving force is the polarization potential established between the solution and the bipolar electrode, that allows a wireless electrochemical addressing. In the past decade or so, bipolar electrochemistry has encountered a remarkable renewal of interest with extraordinary potentialities ranging from materials science to analytical chemistry. For practical reasons, bipolar electrochemistry experiments are very often performed in handmade electrochemical cells comprising tubes or capillaries. This review is focused on specific applications based on such types of experimental setups, from the macroscale where the tube acts only as an ordinary container down to the microscale where specific properties of the capillary come also into play.
双极电极相当独特，因为与传统电化学装置不同，在传统装置中电子转移反应在两个不同电极上进行，而双极电极同时充当阳极和阴极。驱动力是溶液与双极电极之间建立的极化电位，这使得能够进行无线电化学寻址。在过去十年左右的时间里，双极电化学重新引发了人们极大的兴趣，具有从材料科学到分析化学等非凡的潜力。出于实际原因，双极电化学实验通常在由管子或毛细管组成的手工制作的电化学池中进行。本综述聚焦于基于此类实验装置的特定应用，从管子仅作为普通容器的宏观尺度，到毛细管的特殊性质也发挥作用的微观尺度。
