FELICITAS Fuel-cell Powertrains and Clustering in Heavy-duty Transports

FELICITAS aims to develop fuel-cell systems that are capable of meeting the demands of heavy-duty transport for road, rail and marine applications. These systems will be highly efficient, power-dense, durable, robust and reliable. FELICITAS focuses on the development of fuel-cell drive trains capable of meeting the demands of heavy-duty transport for road, rail and marine applications. The main requirements include power levels above 200 kW, power density at about 200 kW/t, system efficiency at about 60%, fuelled by hydrogen and/or hydrocarbon, having robustness and longevity, improved environmental impact and price competitiveness to conventional IC engines. 

The scientific and technological approach in FELICITAS comprises clustering and hybridisation. FELICITAS will contribute by providing improved SOFC technology for marine applications, onboard diesel reforming technology for SOFC powertrains, and gas turbine technology for hybrid SOFC powertrains. In consequence of the so far predominantly stationary application of the SOFCs, significant improvements in performance and design are necessary to meet the requirements of heavy-duty transport. 

Onboard fuel reforming will be a critical issue too within the framework of FELICITAS, because operating on high-energy-density fuels, such as liquid fuels, is essential for long distance operation of heavy-duty vehicles or ships. Addressing the particular demands of marine applications is therefore the first logical step in the use of SOFC for mobile applications. 

FELICITAS will improve PEFC technology in a similar manner by developing PEFC clusters for heavy-duty road and light rail applications and hybrid PEFC clusters with extended durability, efficiency and increased power dynamics. PEFC technology is already well adapted for automotive applications, but the durability and power levels of PEFC remain a challenge: PEFC efficiency does not exceed 50% due to electrochemical restrictions. However, hybridisation and clustering of PEFC modules developed within FELICITAS should be a cost-efficient and practicable way to overcome this limitation
