The transportation sector is undergoing a technology shift from internal combustion engines to electric motors powered by secondary Li-based batteries. However, the limited range and long charging times of Li-ion batteries still hinder widespread adoption. This aspect particularly true in case heavy freight long-range transportation, where solid oxide fuel cells (SOFCs) offer an attractive alternative as they can provide high-efficiency flexible choices. SOFC mainly used for stationary applications owing high operating temperature, low volumetric power density specific power, poor robustness towards thermal cycling mechanical vibrations conventional ceramic-based cells. Here, we present metal-based monolithic cell design overcome these issues. Cost-effective scalable manufacturing processes are employed fabrication, only single heat treatment required, opposed multiple treatments production. optimised through three-dimensional multiphysics modelling, nanoparticle infiltration, corrosion-mitigating treatments. stack shows 5.6 kW/L, thus, demonstrating potential transport applications.
