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.

Abstract: A system includes a vacuum chamber configured to enclose the material sample within, an infrared camera, a power supply, a heating stage, and a temperature controller. The infrared camera is configured to measure a temperature within the vacuum chamber and generate an output temperature value. The heating stage is coupled with a pair of electrodes, and the pair of electrodes are configured to apply a power signal to the heating stage from the power supply to affect the temperature within the vacuum chamber. The temperature controller is configured to receive the output temperature value and selectively adjust the temperature within the vacuum chamber to thereby maintain the temperature within the vacuum chamber within a desired temperature range.

Abstract: A method includes providing steam to the solid oxide fuel cell stack, splitting exhaust gas from the cell stack into two portions, a first portion directed to a superheater and a second portion directed to an ejector and to a hydrogen separator. At least part of the first portion of the exhaust gas that is directed to the superheater is subsequently boiled in a boiler and then returned to the superheater. After being returned to the superheater, this part is directed to the ejector as high pressure steam so as to drive the ejector.
