Abstract: The invention concerns a process for monitoring failure situations related to feed and/or purge flow in electrolyzer cells, stacks or systems, said monitoring process being combined with appropriate actions to be taken in case of such failure situations, wherein (a) the current and/or the voltage are monitored and controlled over a single cell, over all the cells or over one or more selected cells in a stack or a system of stacks, (b) in case the current, the voltage or the ratio between voltage and current crosses its pre-defined threshold value, a failure mode is detected and communicated to the control system, and c) the voltage levels of the system are adjusted to be within safe limits (safe-mode limits).
