16. Functionalized mesoporous carbons as non-precious metal fuel cell catalysts
Sammanfattning : Fuel cells allow for clean and efficient chemical to electrical energy conversion. However, their high price significantly limits the market viability of the technology. This is to a large part due to the high cost of the precious metals used in most fuel cell catalysts. LÄS MER
17. On Hybrid Fuel Cell and Battery Systems for Maritime Applications
Sammanfattning : Hydrogen is seen as a key player in leading to a sustainable energy sector and decarbonizing the transport sector. Proton Exchange Membrane Fuel Cells (PEMFCs) consume hydrogen and oxygen to generate water, heat and electricity. LÄS MER
18. Design and characterization of direct electron transfer based biofuel cells including tests in cell cultures
Sammanfattning : Enzymatic fuel cells (EFCs) are bioelectronic devices based on redox enzymes, which convert chemical energy into electrical energy via biochemical reactions. A major difficulty to overcome is to successfully connect (using e.g., immobilization) the enzymes to the electrode surface. LÄS MER
19. Modelling of a proton exchange membrane fuel cell system for automotive applications
Sammanfattning : .... LÄS MER
20. Control and Optimization of Fuel Cell Based Powertrain for Automotive Applications
Sammanfattning : Fuel cell powered electric vehicles, with fast-refueling time, high energy density, and zero CO2 emissions, are becoming a promising solution for future fossil-free transportation. However, the relatively slow dynamic response and the inability of recovering the regenerative energy make vehicles solely powered by fuel cells not an immediately attractive solution. LÄS MER
