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

Problems Solved: - Efficient water supply management in electrolysis process - Enhanced hydrogen recovery from electrolysis stack

Benefits: - Increased efficiency in hydrogen production - Reduced energy consumption - Improved control over water flow in electrolysis process

Commercial Applications: - Hydrogen production plants - Renewable energy facilities - Fuel cell technology companies

Prior Art: - Prior research on water electrolysis efficiency and hydrogen recovery methods

Frequently Updated Research: - Ongoing studies on water electrolysis stack optimization and performance improvements

Questions about Water Electrolysis Stack: 1. How does the integration of a pump and ion exchanger improve the efficiency of the water electrolysis process? 2. What are the potential environmental benefits of using a water electrolysis stack for hydrogen production?

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.
