Quantifying Individual Potential Contributions Of The Hybrid Sulfur Electrolyzer, John A. Staser, Maximilian B. Gorensek, John W. Weidner

Faculty Publications

The hybrid sulfur cycle has been investigated as a means to produce clean hydrogen efficiently on a large scale by first decomposing H₂SO₄ to SO₂, O₂, and H₂O and then electrochemically oxidizing SO₂ back to H₂SO₄ with the cogeneration of H₂. Thus far, it has been determined that the total cell potential for the hybrid sulfur electrolyzer is controlled mainly by water transport in the cell. Water is required at the anode to participate in the oxidation of SO₂ to H₂SO_{4 …}
