What will you be doing?

Electrolysis of water to generate hydrogen fuel is an attractive renewable energy storage technology. Commercially available water electrolyzers generally operate on high purity water feeds that are achieved by incorporating costly water purification/desalination systems into the overall electrolyzer design which further entail regular maintenance/repair costs. The ability of operate the electrolyzer for hydrogen production directly with sea-water, allows for the removal of the desalinization and purification step which might result in a decrease of the overall process cost. You will be provide support in the fabrication and testing of a novel electrolyzer concept developed at TNO. In addition, you will learn about electrode preparation and characterization employing electrochemical methods such as EIS and CV.
