Abstract
A test device for an electrochemical cell is arranged inside the electrochemical cell in such a way that it is in electrical contact with two current-carrying electrodes of the electrochemical cell. The test device includes a switching device having at least one cathode and one anode partial electrode which are adjacently arranged, but with a space thereinbetween. In an initial state, the switching device is opened such that electrical current cannot flow between the partial electrodes. The switching device is closed in a short-circuit state by bridging the space between the partial electrodes such that an electrical current can flow between the current-carrying electrodes of the electrochemical cell and through the partial electrodes.
