A device for cooling an electrolyser

A device comprising a cell including electrodes and an electrolyte, a chamber on one side of the cell such that the cell is mounted or embedded in a wall of the chamber and a valve through which gas generated in the chamber can be vented. The chamber is relatively large compared to the cell, with the chamber having an internal height that is at least twice the height of the cell. Preferably, the device comprises two chambers, one on each side of the cell such that the cell acts as a divider between the chambers with the chambers linked by a conduit that allows fluid transfer so that pressure difference between the cells is reduced. Ideally, the device is used for the electrolysis of water wherein the water fills the chambers so that the electrolytic cell can be considered to be immersed in the water. Heat is transferred from the electrolytic cell into the surrounding water.
