Bipolar plate, backing pattern for a bipolar plate, system as well as methods for making and testing a bipolar plate

摘要

The invention concerns a bipolar plate (2) for an electrochemical system (1),comprising two interconnected separator plates (2a, 2b),where at least one of the separator plates (2a, 2b) has a plate body (21) and at least one plate body (21) formed at one point with the plate body, over a point of entry (33) of the plate body (21) has a plate body detachable (30, 31, 32, 39). In addition, the invention concerns a back-up model for a bipolar plate or circuit board, a circuit board, a system as well as procedures for the production and testing of a bipolar or circuit board.
