Its objectives are to enhance the Competitiveness and Industrial Development of companies in the Transport and Energy sectors and encourage the use of technology, design and manufacture of new products as well as the development of advanced programs for the improvement of the entire process industrial. They research and develop technologies for the production of clean hydrogen and its subsequent application in transport and building. They have experimental facilities, tools and theoretical models for research in hydrogen technologies.

The CIEMAT Fuel Cells and Systems Integration Unit focuses on the development and application of solid oxide (SOFC) and polymer electrolyte (PEMFC) fuel cells, through the study of basic aspects of electrocatalysis and electrochemical conversion of energy; the search for new materials for components, with special attention to the electrocatalyst; the design and construction of prototypes with incorporation of the developed components; and the integration of hydrogen and fuel cells in systems for energy conversion.
