With increasing wind and solar energy production energy storage becomes increasingly important. Solid Oxide Cells (SOCs) can be used for energy storage since they offer efficient conversion of electricity to fuel and fuel to electricity. Today material costs and lifetime issues prevents a widespread deployment of the SOC technology. However, 3D printed SOCs can potentially result in significantly cheaper and more robust cells. The aim of the project is to construct an SOC electrolyte and electrode backbone using a PiXDRO 3D inkjet printer. First a printable suspension/ink must be created, which is compatible with the print head requirements in terms of viscosity, surface tension and particle size. When a proper ink is made, an electrolyte is printed and on top of this a porous backbone. This backbone can then be impregnated with an electrocatalyst after sintering to make a functional electrode.
