Abstract
A method for improving the efficiency of a water electrolysis system and a system therefor are disclosed. The system includes a stack, a power source configured to supply a voltage to an anode and a cathode of the stack, and a contact electrification pipe connected to the anode such that a fluid circulates within the pipe. The fluid includes at least water. Electric power generated in the contact electrification pipe is supplied to the power source to improve power efficiency.
Claims20
A water electrolysis system comprising:
- a stack;
- a power source configured to supply a voltage to an anode and a cathode of the stack;
- and
- a contact electrification pipe connected to the anode such that a fluid circulates therein,
- wherein the fluid includes at least water, and electric power generated in the contact electrification pipe is supplied to the power source.
A method for improving an efficiency of a water electrolysis system, the method comprising:
- Continuously supplying a fluid comprising at least water to an anode of a stack through a first contact electrification pipe;
- applying a voltage to the anode and a cathode of the stack using a power source;
- recovering the fluid discharged from the anode through a second contact electrification pipe;
- and
- supplying electric power generated in the first contact electrification pipe and the second contact electrification pipe to the power source as additional electric power for the stack by using a triboelectric effect resulting from circulation of the fluid.
