Solid oxide fuel cells (SOFCs) exhibit potential to become a key technology for future clean energy systems. The metal-supported SOFC exhibits decisive strengths like fast start-up capability, mechanical robustness, and acceptable cost, making it the concept of choice mobile applications. As promising example, SOFC-powered range extenders electric vehicles offer refueling significantly increased driving range, while lowering size, weight, cost vehicle's battery. Here, we report development...

Molybdenum manufactured with laser powder bed fusion (LPBF) has an undesirable coarse-grained, columnar microstructure interspersed intergranular cracks, high porosity, and poor mechanical strength. These defects result from a combination of the harsh LPBF process conditions disadvantageous properties molybdenum, such as its brittle-ductile transition temperature low tolerance for oxygen impurities. In order to suppress these defect-forming mechanisms improve suitability LPBF, alloy-side...
Recently, the standard manufacturing route for solid oxide fuel cells has been changed from warm pressing of anode substrate Coat Mix® powders towards tape casting a mixture yttria stabilized zirconia and nickel to substrate. Due different shrinkage behavior, especially heat treatment steps several coating parameters had be adjusted new type. In this contribution, influence processing during on performance single is discussed.
The implementation of thin‐film technologies in energy‐related applications, such as special fuel cells and gas separation membranes for low‐emission power plants, is essential terms enhancing the functionality, reducing operating temperatures, increasing lifetime. Introducing thin electrolyte layers into solid oxide ( SOFC s) decreases internal cell resistance thus drastically enhances density. This supports goal operation temperature from ~800°C to temperatures below 700°C. As lowered,...

Pure suffer from coarse-grained, columnar, cracked microstructure. Material...
The demand for clean and green energy has raised the consumption of hydrogen continuously during last years. Hydrogen is most economically produced in large scale systems by methane steam reforming followed pressure swing adsorption (PSA). However, with a rising small-scale production hydrogen, as down-scaling to smaller PSA-systems ( < 500 Nm3/h H2) not economic, substantial generation using palladium membranes emerged.Porous tubes made an oxide dispersion strengthened powder metallurgy...
