Abstract (en)
[origin: US2009045073A1] Electrolysis cell and method of using the same in hydrogen generation. According to one embodiment, the electrolysis cell includes a frame having an interior. A proton exchange membrane (PEM) is disposed within the frame to divide the interior into two chambers. An anode in the form of a gas diffusion electrode is disposed within the interior of the frame and is spaced apart from the PEM, the space between the anode and the PEM being filled with an aqueous sulfuric acid. A cathode is disposed within the interior of the frame and is ionically coupled to the PEM. In use, gaseous sulfur dioxide is delivered to the side of the anode facing away from the sulfuric acid solution, and a current is supplied to the electrolysis cell. Consequently, sulfur dioxide is oxidized at the anode, and molecular hydrogen is generated at the cathode.
