Abstract

Power is provided to an electrochemical cell. The electrochemical cell includes an anode side and a cathode side. A solution is flowed to the anode side. The solution includes hydrogen sulfide dissolved in water. Water is flowed to the cathode side. The water flowed to the cathode side can be in the form of steam. Providing power to the electrochemical cell facilitates production of sulfur dioxide on the anode side. Providing power to the electrochemical cell facilitates production of hydrogen on the cathode side. A membrane separating the anode side from the cathode side prevents flow of hydrogen sulfide, water, and sulfur dioxide from passing through the membrane while allowing hydrogen cations and oxygen anions to pass through the membrane. Sulfur dioxide is flowed out of the anode side. Hydrogen is flowed out of the cathode side.
