1. An electrolytic system comprising means for degassing a liquid-gas mixture, said means comprising:
an enclosed tank to contain a liquid, the liquid having a normal operating level at an intermediate height within the tank, the tank having:
one or more baffle(s) within the body of the tank, wherein:
at least one of the baffle(s) substantially defines a boundary of a first region and a second region, wherein:
the first region accommodates relatively turbulent conditions for the liquid, and
the second region accommodates relatively calm conditions for the liquid,
wherein there is provided:
a liquid transfer gap for the transfer of liquid from the first region to the second region, and
a gas transfer gap for the transfer of gas from the first region to the second region,
an inlet, the inlet being for the introduction of a liquid-gas mixture from an electrolyzer, and
an antechamber, wherein:
the inlet enters the antechamber, and
the antechamber has an outlet directed towards the first region, the antechamber outlet being above the normal operating level of the liquid, and
a first outlet, wherein:
the first outlet is adapted for the outflow of the substantially degassed liquid, and
the first outlet is situated in the lower half of the tank, substantially below the normal operating level of the liquid and
a second outlet, wherein:
the second outlet is adapted for the outflow of the gas purged from the liquid-gas mixture, and
the second outlet is situated in the upper half of the tank, substantially above the normal operating level of the liquid and
a refill inlet for maintaining the liquid at a desired liquid level, and
wherein a heating element or heat exchanger is provided in combination with a temperature sensor and a control unit for maintaining the temperature of the electrolytic system.

10. A method for degassing a liquid-gas mixture in an electrolytic system, said method comprising the following steps:
providing an enclosed tank for use in an electrolytic system requiring the degassing of a liquid-gas mixture, the tank being adapted to contain a liquid, the liquid having a normal operating level at an intermediate height within the tank, wherein:
one or more baffle(s) in the tank define a first region and a second region, wherein the first region accommodates relatively turbulent conditions for the liquid, and the second region accommodates relatively calm conditions for the liquid, and
a liquid transfer gap is present so liquid can transfer from the first region to the second region, and
a gas transfer gap is present to allow gas to transfer from the first region to the second region;
causing the liquid-gas mixture to flow from an electrolyzer to the tank through an inlet, the inlet being to an antechamber of the tank, and the antechamber having an outlet which is above the normal operating level of the liquid,
flowing the liquid-gas mixture through the antechamber outlet, the liquid-gas mixture then entering the first region, wherein:
the liquid-gas mixture cascades into the first region,
turbulence in the first region encourages the removal of gas dissolved in the liquid-gas mixture,
allowing the substantially degassed liquid to flow from the first region to the second region via the liquid transfer gap, and
causing the substantially degassed fluid to flow from the second region through a first outlet for use elsewhere in the electrolytic system, and
removing gas from the tank via a second outlet, and
providing a refill inlet for maintaining the liquid at a desired liquid level, and
wherein a heating element or heat exchanger is provided in combination with a temperature sensor and a control unit for maintaining the temperature of the electrolytic system.
