METHOD FOR PRODUCING HYDROGEN AND SULFURIC ACID FROM SULFUR DIOXIDE USING ELECTROCHEMICAL PROCESS

摘要

The present invention relates to a method for generating hydrogen and sulfuric acid by injecting a raw ingredient gas into an anode of an electrochemical cell, which is provided with a polymer membrane having ion conductivity, and injecting water into a cathode of the electrochemical cell and performing an electrochemical reaction. The method for generating hydrogen and sulfuric acid from sulfur dioxide gas by using an electrochemical technique is characterized by injecting a sulfur dioxide gas as the raw ingredient gas that is supplied to the anode of the electrochemical cell, and a the mixed gas comprising a mixture of a diluted gas that is selected from oxygen, nitrogen, and air, thereby reducing sulfur dioxide crossover in the cathode of the electrochemical cell.
