AN ECPR MASTER ELECTRODE, AND A METHOD FOR PROVIDING SUCH MASTER ELECTRODE

摘要

An ECPR master electrode (30, 100, 200) is presented. The master electrode comprises a carrier element (31, 101, 201) having an electrically conducting electrode surface (33, 103, 203) on a back side and a topographical pattern on a front side (32, 102, 202) with an at least partly electrically insulating top, said topographical pattern is forming at least one electrochemical cell (34a-d, 104a-d, 204a-d) comprising a bottom and at least one side wall, said bottom having an electrically conducting surface being conductively connected to the electrically conducting electrode surface (33, 103, 203) on the back side through the carrier element (31, 101, 201), wherein said carrier element (31, 101, 201) further comprises an electrical current suppression or blocking structure (39, 120, 220) between said front side (32, 102, 202) and said back side.
