26. Dynamic Solid Oxide Fuel Cell Modelling for Non-steady State Simulation of System Applications
Sammanfattning : Most of the world's energy generation is based on fossil fuels such as coal and oil, which already today but even more in the future, will cause various problems. One issue is their limited availability, which stands in conflict to the increasing global energy consumption. LÄS MER
27. Materials Reliability in PEM Fuel Cells
Sammanfattning : As part of the global work towards reducing CO2 emissions, all vehicles needs to be electrified, or fueled by green fuels. Batteries have already revolutionised the car market, but fuel cells are believed to be a key energy conversion system to be able to electrify also heavy duty vehicles. LÄS MER
28. Structure, interactions and functionality in novel electrolyte materials for fuel cell applications
Sammanfattning : It is today well known that fossil fuels will sooner or later be depleted, and the need to find alternative energy sources is now accepted. Among the diverse technologies developed to produce energy, considerable interest is currently directed to the hydrogen fuel cell, a device that converts chemical into electrical energy, is versatile and has a low environmental impact.

29. Analysis of PEM Fuel Cell Stacks and Systems with Water/Thermal Balances
Sammanfattning : The Proton Exchange Membrane (PEM) fuel cell has been investigated for a long time, and is regarded as a new energy source for various applications, such as portable, stationary and automotive ones. However, due to the shortage of the infrastructure in the society, the high cost, the difficulty of the water/thermal management, etc. LÄS MER
30. Durability evaluation of PEM fuel cell components
Sammanfattning : Proton exchange membrane fuel cells (PEMFCs) are used to convert hydrogen and oxygen to electricity, heat, and water. There are no greenhouse gas emissions, given that the hydrogen is produced from renewable sources, such as water electrolysis from wind, hydro or solar energy. LÄS MER
