Apparatus for generating gas by electrolysis of a liquid comprises an electrolysis cell and a housing for the liquid. The housing comprises a first chamber for storing the liquid for supply to the electrolysis cell, the first chamber having an inlet for replenishing the liquid, and an outlet through which liquid is supplied from the first chamber to the electrolysis cell, and a second chamber for containing liquid which is a product of the electrolysis reaction and which is enriched with a first gaseous product of the electrolysis reaction, the second chamber having a gas outlet for controlled release of the first gaseous product. A first channel in the housing connects the first and second chambers. The channel provides a trap for liquid which can provide a barrier to passage of gas between the first and second chambers, irrespective of the level to which liquid in the first chamber falls during normal operation.
