Participation in the establishment of spin‐off company I was one of the key founders of ADVENT Technologies SA. The company was founded in November 2004 and was co‐financed within the framework of the PRAXE program from the Greek Ministry of Development, with a shared cost action of 700,000 €. ADVENT Technologies SA was established in Patras Greece in November 2004 and I used to chair the company from 2005‐2010. In 2010 ADVENT expanded its activities to connecticat in the USA. The activities of the company focus on the optimization and commercialization of high temperature polymer electrolyte fuel cell technology, based on materials and processes that were developed at FORTH/ICE‐HT and the Department of Chemistry of the University of Patras. The company is currently specialized in the development of high temperature PEM fuel cell stacks based on its proprietary technology.
