Abstract

The present disclosure relates to a backflow suppression system for an electrochemical device, the system comprising: an orifice plate arranged to be connected in an outlet pipeline of an electrochemical device, the orifice plate comprising a restricted orifice for restricting fluid flow through the pipeline; a valve arranged to be connected in the outlet pipeline between the electrochemical device and the orifice plate, the valve being operable to regulate fluid flow along the outlet pipeline; at least one sensor arranged to be connected along the outlet pipeline; and a controller arranged to receive information relating to readings of the sensor and to operate the valve in dependence on the information. The present disclosure also relates to a system comprising the backflow suppression system and at least one electrochemical device.
