Abstract:
1. Apparatus for generating gas by electrolysis of a liquid, comprising: a. an electrolysis cell; b. first chamber for storing the liquid for supply to the electrolysis cell, the first chamber having an outlet through which liquid is supplied from the first chamber to the electrolysis cell, c. 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 an outlet for controlled release of the first gaseous product, d. a third chamber for containing liquid which is a product of the electrolysis reaction and which is enriched with a second gaseous product of the electrolysis reaction, the third chamber having an outlet for controlled release of the second gaseous product, e. a first channel which connects the first and second chambers, f. a second channel which connects the second and third chambers, in which each of the first and second channels provides a trap for liquid which can provide a barrier to passage of gas between the chambers which are connected by it, irrespective of the level to which liquid in the first chamber falls during operation.
