7. Platinum-Based Nanocatalysts for Proton Exchange Membrane Fuel Cells
Sammanfattning : Fuel cells have potential to become an integral technology in a future sustainable energy system. For transport applications, the proton exchange membrane fuel cell (PEMFC) is the most promising option, exhibiting light weight and high energy density. LÄS MER
8. Life cycle navigation through future energy carriers and propulsion options for the energy transition in shipping
Sammanfattning : The shipping industry's heavy reliance on fossil fuels has a detrimental effect on the global climate, human health, and the natural environment. The shipping sector now relies on the use of cheap and energy-dense heavy fuel oil and is perceived as ‘difficult-to-decarbonize’. LÄS MER
9. Applications for Molten Carbonate Fuel Cells
Sammanfattning : Molten Carbonate Fuel cells are high temperature fuel cells suitable for distributed generation and combined heat and power, and are today being installed on commercial basis in sizes from 100kW to several MW. Novel applications for MCFC which have attracted interest lately are MCFC used for CO2 separation from combustion flue gas, and high temperature electrolysis with reversible fuel cells. LÄS MER
10. Hydrogen Generation for Fuel Cells in Auxiliary Power Systems
Sammanfattning : Heavy-duty trucks are in idle operation during long periods of time, providing the vehicles with electricity via the alternator at standstill. Idling trucks contribute to large amounts of emissions and high fuel consumption as a result of the low efficiency from fuel to electricity. LÄS MER
