WebSolid oxide fuel cells (SOFCs) are potential future energy conversion devices. Here, we report infrared vertical-cavity surface-emitting lasers (VCSELs) for the ultrafast fabrication of SOFCs. VCSELs eliminate the organic additives and densify the laminated multilayered SOFC NiO–YSZ NiO–ScCeSZ ScCeSZ GDC (where YSZ Journal of Materials Chemistry … Web10 jan. 2024 · On the surface, a fuel cell which uses hydrogen to create electricity is a commendably efficient way to go. Depending on the actual fuel cell, these devices are reckoned to be between 40 and 60 per cent efficient. That’s partly because hydrogen needs to be compressed into a liquid form that a fuel cell can use, and that costs about 15 per ...
Web21 okt. 2016 · Polymer electrolyte membrane fuel cells—also called proton exchange membrane fuel cells—need only hydrogen, oxygen from the air, and water to operate and do not require corrosive fluids like some fuel cells. This type of fuel cell runs at low temperatures, usually around 80°C, with electrical efficiencies of about 45%.
