Konstruktion av elektrolytisk ozongenerator

Marcus, Malmström, David, Moretti January 2015 (has links)
The work has been carried out in cooperation with the company Zenit Design in Malmö. The project's goal was to restore, improve and produce an ozone generator. During the project, the authors sought relevant literature in databases, been in contact with US suppliers of fuel cell membranes, Asian suppliers for the processing of Teflon and Titanium parts in mechanical engineering and Swedish suppliers of various standard components. The authors had access to a temporary lab at Zenit and electron microscope at Halmstad University where material tests were performed. The authors have also had access to measurement equipment to measure amounts of ozone. During the work, the authors have mapped how an existing ozone generator works and then have their own development. Difficulties with the project have included lead times from suppliers and expensive prototypes that lead to authors only had one chance to succeed. The results from the prototype test showed that the self-made ozone generator is not generating ozone as it should due to the membranes, Zenit will further investigate these.
