The present invention relates to an oxygen generator integrated with an ozone removal filter such that an ozone removal filter is provided in an oxygen discharge opening communicating with an oxygen discharge hole of a water electrolytic cell constituting an apparatus for producing oxygen by using mineral water among generally used water, for filtering ozone generated with oxygen during electrolysis of water and ozone compounds, in which ozone is combined with various organic and inorganic materials contained in mineral water, such as calcium (Ca), magnesium (Mg) and silicon (Si), and thus the oxygen generator allows only high purity oxygen to pass through and to be discharged through the oxygen discharge hole.

A method for the operation of an SOEC stack reactor ( Solid Oxide Electrolyser Cell), according to which, in the absence of electricity, synthesis gas H.sub.2+CO or a mixture H.sub.2+CO.sub.2 is injected at the cathode inlet of the reactor in such a way as to produce methane inside the reactor. Since the catalytic methanation reaction is exothermic, the stack reactor can therefore be held at temperature, without loss of fuel. The fuel used for the methanation (synthesis gas or hydrogen) can advantageously be that which has been previously produced during the operating phases with available electricity.

An HHO gas second fuel is produced in a pressure-resistant container and distributed at a low volumetric rate at multiple locations about the internal combustion engine.

The present invention provides a gas generator and comprises an electrolytic device, a condensing filter device, and a cooling device. The electrolytic device is configured for electrolyzing electrolyzed water to generate hydrogen. The condensing filter device is coupled to the electrolytic device for receiving and filtering the hydrogen generated by the electrolytic device. The cooling device comprises a cooling sheet and a cooling fan, wherein the cooling sheet is configured on the condensing filter device, and the cooling fan is configured for driving air to flow through the cooling sheet to cool the condensing filter device. The present invention uses the condensing filter device and the cooling device for cooling the generated gas and the component that gas passes through, so that a stable operating temperature is maintaining. Therefore, the possibility of the component damage by high temperature and humidity is reduced.
