Thermochemical processes are being developed to provide global-scale quantities of hydrogen. A variant on sulfur-based thermochemical cycles is the hybrid sulfur (HyS) process which uses a sulfur dioxide-depolarized electrolyzer (SDE) to produce the hydrogen. Testing examined the activity and stability of platinum and palladium as the electrocatalyst for the SDE in highly concentrated sulfuric acid solutions. Cyclic and linear sweep voltammetry revealed that platinum provided better catalytic activity with much lower potentials and higher currents than palladium. Testing also showed that the catalyst activity is strongly influenced by the concentration of the sulfuric acid electrolyte.}, issn = {1388-2481}, doi = {10.1016/j.elecom.2007.08.015}, url = {http://www.sciencedirect.com/science/article/pii/S1388248107003451}, author = {H{\'e}ctor R.
