WATER ELECTROLYSIS APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240240328 titled 'WATER ELECTROLYSIS APPARATUS

The abstract describes a water electrolysis stack that includes a water electrolysis cell, a water supply side path for supplying water to the stack, and a hydrogen side path for recovering hydrogen generated from the stack. The water supply side path consists of a pump, an ion exchanger, a bypass, a valve, and a controller.

  • The water electrolysis stack includes a water electrolysis cell laminated within it.
  • The water supply side path features a pump as the power source for supplying water to the stack.
  • An ion exchanger is arranged between the pump and the water electrolysis stack.
  • A bypass allows water to flow from the pump to the stack without passing through the ion exchanger.
  • A valve is included to adjust the amount of water flowing to the bypass.
  • A controller is present to regulate the valve.

Potential Applications: - Industrial hydrogen production - Renewable energy storage - Fuel cell technology

Problems Solved: - Efficient water electrolysis process - Controlled water flow in the system - Optimal hydrogen recovery

Benefits: - Increased hydrogen production efficiency - Enhanced control over water supply - Improved overall system performance

Commercial Applications: Title: "Advanced Water Electrolysis Stack for Industrial Hydrogen Production" This technology can be utilized in industries requiring large-scale hydrogen production, such as chemical manufacturing, energy production, and transportation sectors.

Questions about Water Electrolysis Stack: 1. How does the presence of an ion exchanger improve the water electrolysis process? The ion exchanger helps in maintaining the purity of the water supplied to the electrolysis cell, leading to more efficient hydrogen production.

2. What role does the controller play in the water supply side path? The controller adjusts the valve to regulate the flow of water to the bypass, ensuring optimal operation of the electrolysis stack.


Original Abstract Submitted

a water electrolysis stack in which a water electrolysis cell is laminated, a water supply side path for supplying water to the water electrolysis stack, and a hydrogen side path for recovering hydrogen generated from the water electrolysis stack are provided, and the water supply side path includes a pump which is a power source for supplying water to the water electrolysis stack, an ion exchanger arranged between the pump and the water electrolysis stack, a bypass which is a path for flowing water from the pump to the water electrolysis stack without passing through the ion exchanger, a valve for adjusting an amount of water flowing to the bypass, and a controller for adjusting a valve.
