The BeBoP project, a new EU initiative, is dedicated to improving fuel cell systems for heavy commercial vehicles and various mobility sectors through the development of enhanced components. The project focuses on advancing supporting elements like air compressors, humidifiers, and DC/DC converters, collectively known as the 'balance of plant'. Led by SINTEF AS, the consortium comprises partners from Norway, Germany, France, Italy, and Switzerland, with funding from the European Union and other entities. Over a 42-month period, the project aims to create more efficient, compact, and reliable components that can monitor fuel cell conditions. Key objectives include establishing better system performance and longevity through innovations in the air compressor, humidifier, and DC/DC converter. By collaborating with component specialists and utilizing modeling expertise from DLR and SINTEF, the project strives to optimize operation, reduce power consumption, and minimize hydrogen usage in heavy-duty fuel cell systems. Ultimately, the BeBoP project aims to accelerate the deployment of fuel cell technology on a large scale by developing standardized, industrialized components.
