Meaning of BIPOLAR ELECTRODE in English

BIPOLAR ELECTRODE

"An electrode that is shared by two series-coupled electrochemical cells in such a way that one side of the (usually planar) electrode acts as an anode in one cell and the other side acts as a cathode in the other cell. In storage batteries and fuel cell stacks many cells are usually connected internally, and it is a very efficient design feature to use a single planar structure for electrodes in two neighboring cells and also as the electrical interconnection between them.
