Electrolysis of Aluminum Solutions in a Magnetic Field

Wood, Charles E. 05 1900 (has links)
This investigation is an attempt to verify the original work done by George Antonoff and Anne Rowley, and to contribute specific data on the action of a magnetic field on aluminum cells. Experiments of the type they have described have been performed and an extensive set of data has been collected. It was thought that if the results of Antonoff and Rowley could be duplicated, further investigation would be warranted. However, the experiments have produced negative results. These results are described in detail in these chapters.

Electrolysis of Titanium in Heavy Water

Kopecek, Radovan 29 June 1995 (has links)
The purpose of these studies was to determine if results similar to those of Fleischmann and Pons could be obtained using a titanium cathode instead of palladium in an electrolysis in a heavy water cell. The electrolyte consists of D20 and H2S04• Two experiments have been performed to examine the features of this electrolysis. As titanium shows the same properties to attract hydrogen, it seemed possible that excess heat could be produced. Radiation was monitored, and the surface of the titanium cathode was examined before and after electrolysis for any changes in the morphology and composition, hoping to discover new elements that can be created only by fusion reactions in the cell, i.e. by transmutation. The heat and radiation effects have been evaluated in comparison to a control cell, using the same electrolyte and current. The only difference was the cathode, which was of platinum. It appears that excess heat is produced during electrolyses of heavy water with a titanium cathode. The amount of this excess heat was 750 cal in a one hour period, an energy gain of 44%. No significant emission of any of the products associated with a "classical" deuterium-deuterium fusion was observed during either experiment, i.e. heat but no radiation. Unexpected elements were found in both experiments, i.e. K. Cr, Fe, Ni and Zn. Remarkable is the fact that the new elements always occur very close in the periodic table to an impurity element, i.e. Cu and Zn.

Electrochemical Splitting of Sodium Sulfate

Davis, Samuel M. 22 May 2006 (has links)
Five cation exchange membranes and four anion exchange membranes were tested in a three-compartment, two-membrane, electrolysis salt-splitting cell for the recycle of sodium sulfate into sodium hydroxide and sulfuric acid. The cell is further examined using DuPont Nafion 324 cation exchange membrane and Sybron Ionac MA-7500 anion exchange membrane to determine the maximum concentration of sodium hydroxide that can be produced by electrolysis salt-splitting as well as to determine the chief source of inefficiency. The discussion includes recommendations for future electrolysis salt-splitting cells and a mathematical model of the cell is created to determine optimum operating conditions.

Hydrogen future

Whittaker, Alexander January 2015 (has links)
Hydrogen electrolysis has gone through a number of stages in research and applications. From what we can see from this report, there are several ways of producing hydrogen electrolysis, and several applications. The main purposes of this report however, is not to describe what hydrogen electrolysis is and its applications. Research and experiments has already proven that it is a functioning technology. The aim is to gather the necessary information, both theoretically and practically to be able, from a technical and business point of view analyze if this in fact is a realistic solution. To maintain a system of sustainable energy has always been an attractive market and there has existed a number of technologies that has had their share of the fame. However, most of these solutions have shown not to be viable, lucrative or technically scalable. Hence, the important issue to address is whether this is a solution worth investing in. The information gathered for the theory is based on technical reports, academic scripture and literature. All of which can be back tracked to its original source. The practical test is done by using a test kit made for universities and other institutes to better understand how hydrogen electrolysis works. The materials used are all scientifically acceptable according to the theories and technologies surrounding hydrogen electrolysis. Hence, the data gathered from the test kits are all accurate according to current research.
