Method for producing hydrogen used in fuel cell, by electrolysis of water, involves storing waste heat generated during electrolysis of water and converting heat energy into electrical energy by steam turbine process

摘要

The waste heat generated during the electrolysis of water (1) is stored, and the heat energy is converted into electrical energy by steam turbine process. The temperature level of the waste heat is raised by the heat pump process which is performed in two stages. The hydrogen (3) and/or oxygen (4) generated by the electrolysis is utilized in a fuel cell to produce electric current (18). An independent claim is included for production device of hydrogen by electrolysis of water.
