Hydrogen Generator Capable of Selectively Adjusting Gas Flow Direction

A hydrogen generator capable of selectively adjusting gas flow direction, comprising:

• an electrolytic module configured to electrolyze water to generate gas comprising hydrogen;
• a water tank configured to accommodate the water and fluidly coupled to the electrolytic module for receiving the gas comprising hydrogen from the electrolytic module;
• a condenser stacked fluidly coupled to the water tank for receiving and condensing the gas comprising hydrogen;
• a humidification cup fluidly coupled to the condenser and configured to accommodate a supplementary water and humidify the gas comprising hydrogen;
• an integrated passageway device stacked above the water tank, comprising a plurality of channels, a gas inlet passageway, and a gas outlet passageway, wherein the gas inlet passageway is configured to receive the gas comprising hydrogen, and the gas outlet passageway is configured to output the gas comprising hydrogen;
• and
• a valve assembly configured to selectively make the gas comprising hydrogen from the water tank to flow into the condenser and the humidification cup, and also to selectively make the supplementary water to flow from the humidification cup into the condenser and the water tank;
• wherein, the integrated passageway device comprises a space for accommodating the condenser;
• the condenser and the humidification cup are directly coupled to the integrated passageway device.
