The proposal is based on bringing together diverse backgrounds of the partners and creating a synergy between self-experiences to be applied to the development of novel PEMFC components. We believe that transnational cooperation of research units highly specialized in different aspects of the proposed work is the key to success. The consortium was built to go far because we are TOGETHER. In this way the consortium will provide solutions to our common problem: the clean energy transition and contribute to the goal of climate neutrality by 2050 and will generate critical mass and building structure for further cooperation and territorial cohesion.
